Add MCP server support (#1137)

* add a generic MCP client and a config for connecting MCP servers

* Add MCP docs and CLI polish: docs page, startup connect summary, --mcp-config flag, compact tool output

* Add MCP connection notes and per-run selection; clean up on cancel and dedupe names

* Show errored MCP tool calls as failed in the TUI

* Sanitize namespaced tool names so model APIs accept them

* Show MCP tool calls distinctly in the terminal and the run viewer

* Say what MCP servers are worth connecting for

* Correct the notes docstring to match how notes reach the agent

* keep the mcp tests from reading your shell's STRIX_MCP_* vars

+# Strix — Agent Guide
+
+Strix is an open-source autonomous AI pentesting tool. This file is for AI coding agents that want to **use** Strix (run security scans) or **contribute** to it.
+
+## Using Strix from an agent
+
+Install the agent skills for step-by-step workflows:
+
+```bash
+npx skills add usestrix/strix
+```
+
+- `penetration-testing-with-strix` — run a headless pentest against code, URLs, domains, or IPs and read results (covers both run modes below)
+- `managed-pentesting-with-strix` — drive the managed app.strix.ai platform via REST (no local Docker/LLM needed)
+- `fix-security-vulnerabilities-with-strix` — remediate findings and re-run Strix to verify
+- `ci-security-scanning-with-strix` — add PR scanning to CI/CD (self-hosted CLI or managed app)
+
+Target-specific workflows built on the same engine:
+
+- `application-security-testing` — whole-product AppSec review: pick the right test per asset, then rank the results
+- `web-app-penetration-testing` — black-box pentest of a live web app or staging site
+- `api-security-testing` — REST/GraphQL APIs and the OWASP API Security Top 10 (BOLA/IDOR, authz)
+- `owasp-top-10-testing` — systematic OWASP Top 10 assessment with honest per-category coverage
+- `find-security-vulnerabilities-in-code` — white-box review of a repo or working tree
+
+**Two ways to run, same engine — pick per situation:**
+
+- **Open-source CLI (self-hosted):** free, fully local, BYO LLM key, needs Docker. Best for local dev loops, air-gapped/offline, and full control.
+  ```bash
+  curl -sSL https://strix.ai/install | bash        # install
+  export STRIX_LLM="openai/gpt-5.4"                 # any LiteLLM model id
+  export LLM_API_KEY="<key>"
+  strix -n -t ./ --scan-mode quick --max-budget 10  # headless scan; always use -n
+  ```
+  - Requires Docker running. Scans take minutes (`quick`) to hours (`deep`) — run in the background.
+  - Exit codes (headless): `0` clean, `1` fatal error, `2` vulnerabilities found. A `0` only covers what was analyzed — check `run.json` (`status`, `llm_usage.cost` vs the budget) before calling a run clean.
+  - Artifacts in `strix_runs/<run-name>/`: `penetration_test_report.md`, `vulnerabilities/*.md`, `vulnerabilities.json`, `findings.sarif` (SARIF 2.1.0), `run.json`.
+
+- **Managed cloud (app.strix.ai):** no Docker, no LLM key, no local install; adds team dashboards, scheduling, PR reviews, and downloadable PDF/DOCX reports (Enterprise plan). Best in sandboxed/CI environments and for teams. Use it when local infra isn't available.
+  ```bash
+  # token from Settings → API Access; register the target as an asset, then:
+  curl -sS https://app.strix.ai/api/v1/scans -H "Authorization: Bearer $STRIX_API_TOKEN" \
+    -H "Content-Type: application/json" -d '{"engagement_type":"live_test","domain_ids":["<uuid>"]}'
+  ```
+  - API docs: https://docs.app.strix.ai (OpenAPI: https://docs.app.strix.ai/openapi.json).
+
+- CLI docs index for LLMs: https://docs.strix.ai/llms.txt (full: https://docs.strix.ai/llms-full.txt).
+- Only scan targets the user is authorized to test.
+
+## Contributing to this repo
+
+- Python 3.12+, managed with `uv`. Install dev deps: `make dev-install`.
+- Lint/format/type-check/security, all in one: `make check-all` (ruff, mypy, bandit).
+- Tests: `uv run pytest`.
+- Run from source: `uv run strix --target <target>`.
+- Layout: `strix/agents` (agent graph + prompts), `strix/tools` (proxy, browser, terminal, scanners), `strix/runtime` (Docker sandbox), `strix/report` (findings, SARIF), `strix/skills` (internal knowledge packs the pentest agents load — different from the consumer skills in `skills/`), `strix/interface` (CLI/TUI), `containers/` (sandbox image).
+- Pre-commit hooks: `make pre-commit` (or `uv run pre-commit install`).

 `strix view` starts a lightweight local server (bound to `127.0.0.1` on a random port) and opens your browser to a private, tokened link. Nothing leaves your machine: the dashboard reads the run's files straight off disk, with no cloud account or upload required. The UI ships prebuilt with Strix, so there is no extra install and no JS build step.
 
+Use `--host 0.0.0.0` to make the viewer reachable from other machines. Replace `0.0.0.0` in the printed URL with the server's reachable IP or hostname. The token in that URL grants access to the selected run's scan data, history, and steering, so only share it with trusted users and restrict the port with your firewall. Requests without the token-derived session cannot read run data.

+#### Connect your own MCP servers
+
+Strix can connect to Model Context Protocol (MCP) servers you list and expose their tools to the agent during a run. Create `~/.strix/mcp-servers.json` with a JSON list of servers. Each entry is either a local `stdio` server that Strix launches as a subprocess, or a remote `http` server:
+
+```json
+[
+  {
+    "name": "local_fs",
+    "transport": "stdio",
+    "command": "npx",
+    "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/project"]
+  },
+  {
+    "name": "github",

+    "auth": { "kind": "bearer", "token": "your-token" },
+    "allowed_tools": ["list_issues"]
+  }
+]
+```
+
+Each server's tools are namespaced by `name` (for example `local_fs_read_file`). Omit `allowed_tools` to expose every tool the server offers, or set it to a list to restrict which tools the agent can call. The file is optional, and a server that fails to connect is skipped without failing the run. You can point Strix at a different file with `STRIX_MCP_CONFIG`.

+```

+| `owasp-top-10-testing` | Systematic OWASP Top 10 assessment with honest per-category coverage |
+| `find-security-vulnerabilities-in-code` | White-box security review of a repo or working tree, with exploits to confirm findings |
+
+Install a single skill with `npx skills add usestrix/strix --skill penetration-testing-with-strix`, or use one without installing:
+
+```bash
+npx skills use usestrix/strix@penetration-testing-with-strix | claude
+```
+
+## Two ways to run — self-hosted or managed
+
+Both use the same engine and produce the same validated findings and SARIF, so agents can pick per situation or combine them:
+
+- **Open-source CLI (self-hosted)** — runs locally in a Docker sandbox with your own LLM key. Free, fully local, air-gap capable. Best for local dev loops and full control.
+- **Managed cloud** — runs on Strix's infrastructure via the [app.strix.ai REST API](https://docs.app.strix.ai). No Docker, no LLM key, no local install; adds team dashboards, scheduling, PR reviews, and downloadable PDF/DOCX reports (Enterprise plan). Best in sandboxed/CI environments and for teams. Create an API token under **Settings → API Access**; the `managed-pentesting-with-strix` skill has the full flow.
+
+## Agent-Friendly Interfaces
+
+Everything an agent needs is machine-readable:
+
+- **Headless CLI** — `strix -n` runs without the TUI and exits with `0` (clean), `1` (error), or `2` (vulnerabilities found).
+- **REST API** — the managed platform exposes a documented [OpenAPI](https://docs.app.strix.ai/openapi.json) at `https://app.strix.ai/api/v1` (scans, vulnerabilities, assets, PR reviews, schedules, webhooks) with bearer tokens and scopes.
+- **Structured results** — every run writes `vulnerabilities.json`, `vulnerabilities.csv`, `findings.sarif` (SARIF 2.1.0), and per-finding Markdown under `strix_runs/<run-name>/`; the cloud exposes the same as JSON plus SARIF export.
+- **Budget controls** — `--max-budget` and `--max-turns` give agents hard cost/time caps.
+- **`AGENTS.md`** — the [repository's agent guide](https://github.com/usestrix/strix/blob/main/AGENTS.md) with a quick reference.
+- **`llms.txt`** — this documentation is indexed at [docs.strix.ai/llms.txt](https://docs.strix.ai/llms.txt) and fully exported at [docs.strix.ai/llms-full.txt](https://docs.strix.ai/llms-full.txt); every page is also available as Markdown by appending `.md` to its URL.
+
+## Example Prompts
+
+Once the skills are installed, prompts like these just work:
+
+```text
+Pentest this repo with Strix (quick mode, $10 budget) and summarize the findings.
+```
+
+```text
+Fix all critical and high findings from the last Strix run, then re-scan to verify.
+```
+
+```text
+Add Strix security scanning to our GitHub Actions so every PR gets tested.

+title: "MCP Servers"
+description: "Connect your own MCP servers and expose their tools to the agent"
+---
+
+Strix can connect to [Model Context Protocol (MCP)](https://modelcontextprotocol.io) servers you list and expose their tools to the agent during a run. Use this to let the agent read how your system is actually built instead of inferring it from the outside.
+
+A few things it pays off for:
+
+- **A database server.** The agent can read the schema and access policies and see tables left readable without them, rather than guessing from responses.
+- **A hosting or infrastructure server.** Deployments, domains and environment variable names tell it what is really running, so it tests what exists instead of what it discovered by crawling.
+- **An issue tracker.** Known and accepted risks stop the agent re-reporting findings you already triaged.
+- **A logging server.** Reading logs lets it confirm an exploit attempt actually landed instead of inferring it from a status code.
+
+## Setup
+
+Create the file `~/.strix/mcp-servers.json`. It holds a JSON list of the servers you want the agent to reach. Each entry is either a local `stdio` server that Strix launches as a subprocess, or a remote `http` server.
+
+Create the directory if it does not exist, then write the file:
+
+```bash
+mkdir -p ~/.strix
+```
+
+Paste the servers you want into `~/.strix/mcp-servers.json`. The example below shows one of each transport: a local filesystem server over `stdio` and a remote GitHub server over `http` with a bearer token:
+
+```json
+[
+  {
+    "name": "local_fs",
+    "transport": "stdio",
+    "command": "npx",
+    "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/project"]
+  },
+  {
+    "name": "github",
+    "transport": "http",
+    "url": "https://api.githubcopilot.com/mcp/",
+    "auth": { "kind": "bearer", "token": "your-token" },
+    "allowed_tools": ["list_issues"]
+  }
+]
+```
+
+Strix reads this file at the start of each run. There is no default file, so no MCP tools are loaded until you create it. Edit `command`, `args`, `url`, and `token` to match your own servers.
+
+## Fields
+
+<ParamField path="name" type="string" required>
+  A short label for the connection. Each server's tools are namespaced by
+  `name` (for example `local_fs_read_file`), so two servers can offer the same
+  tool name without colliding.
+</ParamField>
+
+<ParamField path="transport" type="string">
+  `stdio` for a local subprocess server, or `http` for a remote server.
+</ParamField>
+
+<ParamField path="command" type="string">
+  For `stdio` servers: the executable Strix launches (for example `npx`).
+</ParamField>
+
+<ParamField path="args" type="array">
+  For `stdio` servers: the arguments passed to `command`.

+  `{ "kind": "bearer", "token": "your-token" }`.
+</ParamField>
+
+<ParamField path="allowed_tools" type="array">
+  Restrict which tools the agent can call. Omit it to expose every tool the
+  server offers, or set it to a list of tool names to allow only those. Strix
+  does not decide for you which of a server's tools only read and which change
+  things, so run the server in its own read-only mode if it has one.
+</ParamField>
+
+<ParamField path="notes" type="string">
+  Free-text notes for the agent about what this connection is and how you want
+  it used, for example "Staging analytics database, read-only, prefer aggregate
+  queries." When set, the notes are given to the agent at the start of the run
+  as a description of the connection.
+</ParamField>
+
+## Choosing connections per run
+
+By default every connection in the file is used on each run. To narrow it for a
+single run without editing the file, use either flag (both repeatable):
+
+```bash
+strix --mcp-server github -t ...        # use only the named connection(s)
+strix --mcp-exclude staging-db -t ...   # use everything except the named one(s)
+```
+
+`--mcp-server` keeps only the connections you name; `--mcp-exclude` drops the
+ones you name. Connection names must be unique in the file; if two entries share
+a name, the first is kept and the rest are ignored.
+
+## Pointing at a different file
+
+To read the config from another path instead of `~/.strix/mcp-servers.json`, either pass `--mcp-config <path>` on the command line:
+
+```bash
+strix --mcp-config ./mcp-servers.json -t ...
+```
+
+or set the `STRIX_MCP_CONFIG` environment variable to that path. The flag takes precedence when both are given.
+
+## Startup confirmation
+
+When servers are configured, Strix prints a one-line summary at scan startup, for example `MCP: connected 1 server (14 tools): local_fs`, so you can confirm your servers connected.
+
+## Seeing the calls
+
+Each call the agent makes to one of your servers is shown with its own icon and
+labelled with the connection it went out to, in the terminal and in the run
+viewer (`strix view`), so a call that left Strix for a server you connected is
+easy to pick out of a transcript. The terminal shows the call and its arguments;
+results can be large and arbitrary, so read them in the viewer, which shows a
+preview you can expand.
+
+## Behavior
+
+- The config file is optional. Without it, a run simply gets no MCP tools.
+- A server that fails to connect is skipped and logged, and the run continues without it.
+- A single malformed entry is skipped without blocking the valid ones.

+## Workspace files
+
+Instructions become part of the prompt. To give Strix a file to work with, such
+as a wordlist, an API specification, or notes, use `--workspace-file`. Strix
+places the file into the sandbox workspace before the scan starts.
+
+```bash
+strix --target https://app.com --workspace-file ./wordlist.txt
+```
+
+The file lands at `/workspace/<file name>`. To choose the destination, write
+`PATH:DEST`. `DEST` is a path inside `/workspace`.
+
+```bash
+strix --target https://app.com \
+  --workspace-file ./openapi.yaml:specs/openapi.yaml \
+  --workspace-file ./notes.md
+```
+
+Repeat the option for every file you want to place. Strix lists the files in the
+agent task, so the agent knows where to read them.
+
+Rules that apply to every workspace file:
+
+- The file is read-only inside the sandbox.
+- The destination must stay inside `/workspace`.
+- The destination must not fall inside a target directory, because target files
+  come from the target itself. Strix skips such a file and logs a warning.
+- Two files cannot claim the same destination.
+
+<Note>
+A workspace file is data for the agent to use. It is not a scan target, and its
+contents do not change the instructions.
+</Note>
+
+<Warning>
+Do not place secrets in a workspace file. The sandbox runs untrusted target
+code, so treat anything you place there as readable by the target.
+</Warning>

+description: Security-test a REST, GraphQL, or gRPC API with Strix — autonomous agents that enumerate endpoints from an OpenAPI/GraphQL schema (or by crawling), then actually exploit the API-specific vulnerability classes in the OWASP API Security Top 10 (2023) — broken object-level authorization (BOLA/IDOR), broken object property level authorization (excessive data exposure and mass assignment), broken function-level authorization, unrestricted resource consumption, SSRF, injection, and auth/token flaws. Every finding comes with a working proof-of-concept request. Use when the user asks to pentest, security-test, audit, or find vulnerabilities in an API, endpoint, or backend service.

+
+# Security-test an API
+
+APIs fail differently from web UIs: there is no rendered surface to crawl, the interesting bugs are authorization-shaped rather than injection-shaped, and the same endpoint behaves differently per token. This workflow targets those specifics with Strix's autonomous agents, using the current [OWASP API Security Top 10 (2023)](https://owasp.org/API-Security/editions/2023/en/0x11-t10/) as the coverage checklist. For the web-app equivalent, the current edition is the OWASP Top 10:2025 — see **owasp-top-10-testing**.
+
+Install, LLM setup, full CLI flags, and the managed-cloud path are in the **penetration-testing-with-strix** skill. Read it if `strix --version` fails or the target is not an API.
+
+## 1. Gather what the agents need
+
+APIs are near-impossible to test blind, so collect first:
+
+| Input | Why it matters |
+|---|---|
+| **Schema** — OpenAPI/Swagger file, Postman collection, GraphQL endpoint (introspection), or a gRPC `.proto` | Turns guesswork into full endpoint enumeration. Biggest single win in coverage. An OpenAPI/Swagger or Postman spec (`.json`/`.yaml`/`.yml`) is a target Strix takes directly; a `.proto` is not, so pass it with `--workspace-file`. |
+| **Two sets of credentials/tokens**, ideally in different tenants | BOLA/IDOR — API1:2023, still the #1 API risk — can only be *proven* by accessing tenant A's objects with tenant B's token. |
+| **A low-privilege and a high-privilege token** | Required to prove broken function-level authorization (API5:2023 — a `user` calling admin-only routes). |
+| **Example object IDs** | Lets agents test ID tampering immediately instead of hunting for valid identifiers. |
+| **Out-of-scope routes** | Payments, mass notification, destructive admin endpoints. |
+| **Rate limits / WAF** in front of the API | Avoids agents burning budget on throttled requests; mention them so testing adapts. |
+
+Ask the user for anything missing — do not fabricate tokens or scan an API they do not own.
+
+## 2. Run the scan
+
+Pass the spec as a **target**, not as prose in the instruction — Strix parses OpenAPI/Swagger (`.json`/`.yaml`) and Postman collection exports directly, so the agents start from the real endpoint list:
+
+```bash
+strix -n -t ./openapi.yaml -t https://api.staging.example.com --max-budget 20 \
+  --instruction "Tenant A token: <tokenA> (org 1111, user id 11, order id 501).
+Tenant B token: <tokenB> (org 2222, user id 22).
+Admin token: <tokenAdmin>.
+Focus: BOLA across orgs (API1), function-level authz on /admin/* (API5), object property level authz on PATCH /users/{id} — both mass assignment and over-exposed fields in list responses (API3), unrestricted resource consumption (API4).
+Out of scope: POST /billing/*, POST /notifications/broadcast."
+```
+
+- **Postman instead of OpenAPI:** a collection export works as a target (`-t ./collection.postman_collection.json`), or pull one live with `-t postman://<collection-uuid>` (optionally `"postman://<collection-uuid>?env=<environment-uuid>"`), which needs `POSTMAN_API_KEY` in the environment.
+- **Many services at once:** put one target per line in a file and pass `--target-list ./targets.txt`, repeatable and combinable with `-t`.
+- **Add the backend source for depth:** `-t ./services/api -t https://api.staging.example.com`. With code access the agents can reason about authorization checks and object ownership rather than inferring them from responses.
+- **gRPC:** target the endpoint and pass the definition as a workspace file, `-t https://grpc.staging.example.com --workspace-file ./service.proto`. Only `.json`, `.yaml`, and `.yml` specs are recognized as targets, so `-t ./service.proto` fails with "Path exists but is not a directory".
+- **GraphQL:** point at the GraphQL endpoint and say whether introspection is enabled; call out that you want batching/aliasing abuse, depth/complexity limits, and per-field authorization tested.
+- **Internal/private APIs** unreachable from your machine: use the managed platform's network connector — see **managed-pentesting-with-strix**.
+- Use `--instruction-file` when the credential/context block gets long, and keep tokens out of shell history and out of committed files.
+- **Supporting files** the agents should read but not test, such as an endpoint wordlist or handwritten notes about the tenancy model: pass `--workspace-file ./notes.md`. The file lands read-only in `/workspace`. Add `:DEST` to choose the path, for example `--workspace-file ./wordlist.txt:lists/wordlist.txt`.
+
+## 3. Verify findings
+
+`strix_runs/<run>/penetration_test_report.md` first, then `vulnerabilities/*.md` — each contains the exact request that proved the issue. Replay it (for example, with `curl`) before reporting; for authorization findings, confirm the response really contains the other tenant's data rather than an empty 200.
+
+`findings.sarif` uploads to GitHub code scanning; `vulnerabilities.json` is the structured index for ticketing.
+
+## 4. Fix, re-test, and keep it tested
+
+Remediate with **fix-security-vulnerabilities-with-strix** (fix the authorization check, not the single endpoint), then re-run against the same target to prove the exploit is dead. Wire it into pull-request CI with **ci-security-scanning-with-strix** so new endpoints get tested as they ship.

+# Application security testing
+
+Entry point for "make my application secure" requests, where the target is not yet a single URL or repo. The job here is to pick the right test per asset, run it, and produce one ranked plan — not to run everything at maximum depth.
+
+Install, LLM setup, all CLI flags, and the managed-cloud path live in the **penetration-testing-with-strix** skill. Read it first if `strix --version` fails.
+
+Only test assets the user owns or is authorized to test. Confirm authorization before the first run, and prefer staging over production, because the agents send real exploit payloads and can change data.
+
+## 1. Map the assets
+
+Ask (or read from the repo) and write the answers down before scanning:
+
+- **Source** — one repo, a monorepo, several services? Which languages/frameworks?
+- **Running environments** — is there a staging deployment? A public production site? A local dev server only?
+- **APIs** — REST, GraphQL, gRPC? Is there an OpenAPI/GraphQL schema?
+- **Authentication** — can you get two test accounts in different tenants? Most high-impact bugs need them.
+- **Constraints** — out-of-scope paths, whether production may be touched, budget and wall-clock limits.
+
+If there is no staging environment and production is off limits, say so early. A code-only review is still valuable, but it cannot prove exploitability against a live app.
+
+## 2. Pick the right test per asset
+
+| Asset | Skill to use |
+| --- | --- |
+| Repository or working tree | **find-security-vulnerabilities-in-code** |
+| Live web app or staging site | **web-app-penetration-testing** |
+| REST/GraphQL/gRPC API | **api-security-testing** |
+| Assessment mapped to OWASP categories | **owasp-top-10-testing** |
+| Every pull request, continuously | **ci-security-scanning-with-strix** |
+| No Docker, no LLM key, or a report an auditor will accept | **managed-pentesting-with-strix** |
+
+Those skills carry the flags, credential handling, and result-reading details. Do not duplicate their instructions here.
+
+Sequence for a first assessment:
+
+1. Review the code. It is the cheapest run and it maps the authorization model.
+2. Pentest staging with credentials, and pass the repo as a second target so the agents keep source context.
+3. Add CI scanning, so later regressions are caught without another manual pass.
+
+Run one asset at a time and read each report before starting the next. Findings from the code review make the live run sharper.
+
+## 3. Consolidate into one plan
+
+Findings arrive per run in `strix_runs/<run>/`. Merge them into a single list and rank by **proven impact**, not by scanner severity:
+
+1. Validated exploits reachable without authentication.
+2. Validated cross-tenant or privilege-escalation issues.
+3. Validated issues needing an authenticated account.
+4. Unproven observations (configuration, dependency, and hardening notes) — flag as such, and never present them as confirmed vulnerabilities.
+
+Deduplicate: the same root cause often surfaces in both the code review and the live pentest.
+
+## 4. Be honest about coverage
+
+State plainly what was *not* tested — assets with no staging environment, categories a black-box run cannot reach (logging and alerting, supply-chain integrity, insecure design), and any run that hit its budget or turn cap before finishing. Check `run.json` status and cost against `--max-budget` for each run. An empty result set from a truncated scan is not a clean bill of health.
+
+Then remediate with **fix-security-vulnerabilities-with-strix**, which re-runs Strix against each fix to prove the exploit no longer works.

+# Set up Strix in CI/CD
+
+You can gate PRs two ways — pick based on the environment, or combine them:
+
+- **Managed platform (recommended for most teams)** — connect the GitHub/GitLab/Bitbucket app once and Strix reviews every PR with **no workflow file, no runner, no Docker, and no LLM key**. Results post as PR comments and land in the team dashboard. Best when you want zero CI maintenance, central tracking, or your runners lack Docker. See "Managed platform" below and the **managed-pentesting-with-strix** skill.
+- **Self-hosted OSS CLI in your runner** — run a diff-scoped scan as a pipeline step. Fully in your infra, free (BYO LLM key), no external account. Requires Docker on the runner. Best for air-gapped/self-hosted CI or when you do not want scans leaving your environment.
+
+Both fail the build on validated findings and both emit SARIF 2.1.0, so you can start with one and add the other later.
+
+---
+
+# Option A — Self-hosted OSS CLI in the runner
+
+Run a diff-scoped Strix scan on every PR: only changed files are tested, `quick` mode keeps it fast, and exit code `2` fails the build when validated vulnerabilities are found.
+
+## GitHub Actions
+
+Create `.github/workflows/security.yml`:
+
+```yaml
+name: Security Scan
+
+on:
+  pull_request:
+
+jobs:
+  strix-scan:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+        with:
+          fetch-depth: 0   # required for diff-scope resolution
+
+      - name: Install Strix
+        run: curl -sSL https://strix.ai/install | bash
+
+      - name: Run Security Scan
+        env:
+          STRIX_LLM: ${{ secrets.STRIX_LLM }}
+          LLM_API_KEY: ${{ secrets.LLM_API_KEY }}
+        run: strix -n -t ./ --scan-mode quick --max-budget 10
+
+      # Don't fail open: a run that hits the hard budget stop exits 0 but leaves
+      # run.json status "stopped", not "completed". Enforce completion explicitly.
+      # This does not catch an agent that wrapped up early on a budget *warning*
+      # (it still calls finish_scan and records "completed"), so size the budget.
+      - name: Fail unless the scan completed
+        run: |
+          run_json=$(ls -t strix_runs/*/run.json | head -1)
+          status=$(jq -r .status "$run_json")
+          if [ "$status" != "completed" ]; then
+            echo "Strix run status is '$status' — the scan did not complete (likely budget exhausted). Raise --max-budget." >&2
+            exit 1
+          fi
+```
+
+Then tell the user to add two repository secrets: `STRIX_LLM` (model id, for example `openai/gpt-5.4`) and `LLM_API_KEY` (the provider key). Do not create these values yourself.
+
+Notes:
+- In CI/headless runs Strix automatically scopes to the PR's changed files (`--scope-mode auto`). If diff resolution fails, keep `fetch-depth: 0` or set `--diff-base` to the PR's actual base branch — use `origin/${{ github.base_ref }}` in GitHub Actions rather than a hard-coded `origin/main`, since repos use different default branches.
+- Exit codes: `0` pass, `2` vulnerabilities found (fails the job), `1` setup error.
+- The runner needs Docker (default GitHub-hosted Ubuntu runners have it).
+- **Size the budget so the scan completes — do not let it fail open.** A `0` exit means "no validated vulnerabilities in what was analyzed"; if `--max-budget` is hit before the diff is fully covered, the scan wraps up early and can still exit `0`. The "Fail unless the scan completed" step above narrows the gap: `strix_runs/<run>/run.json` is `"stopped"` when the scan was cut off at the hard budget limit without a final report. It is not a complete guard — the agents get graduated wrap-up warnings before that limit, and a run that wraps up on a warning still calls `finish_scan` and records `"completed"` with partial coverage. So keep that step in any pipeline that gates merges **and** give the scan real headroom (compare `run.json`'s `llm_usage.cost` against `--max-budget`; if it ran right up to the cap, raise it). For a `quick` diff-scoped PR scan `--max-budget 10` is usually ample, raise it for large diffs.
+
+### Optional: upload findings to GitHub code scanning
+
+Strix writes SARIF 2.1.0 to `strix_runs/<run>/findings.sarif`:
+
+```yaml
+      - name: Upload SARIF
+        if: always()
+        uses: github/codeql-action/upload-sarif@v3
+        with:
+          sarif_file: strix_runs
+```
+
+## Other CI systems
+
+Any pipeline works the same way — install, set the two env vars, run headless:
+
+```bash
+curl -sSL https://strix.ai/install | bash
+# Resolve the PR's base branch robustly (use your CI's base-branch variable if it
+# has one, for example GitHub Actions: origin/${{ github.base_ref }}). Avoid piping the
+# git lookup into another command — a failed lookup would otherwise be masked.
+BASE_BRANCH="${CI_MERGE_REQUEST_TARGET_BRANCH_NAME:-}"   # GitLab MR target
+if [ -z "$BASE_BRANCH" ]; then
+  BASE_BRANCH=$(git symbolic-ref --quiet --short refs/remotes/origin/HEAD 2>/dev/null)
+  BASE_BRANCH="${BASE_BRANCH#origin/}"
+fi
+DIFF_BASE="origin/${BASE_BRANCH:-main}"
+# Fail loudly rather than silently narrowing scope (for example, to HEAD~1, which on a
+# multi-commit branch would scan only the last commit and let earlier ones pass).
+if ! git rev-parse --verify --quiet "$DIFF_BASE" >/dev/null; then
+  echo "Cannot resolve diff base '$DIFF_BASE'. Fetch the base branch (git fetch origin <base>) or set --diff-base explicitly." >&2
+  exit 1
+fi
+strix -n -t ./ --scan-mode quick --scope-mode diff --diff-base "$DIFF_BASE" --max-budget 10
+```
+
+Gate the pipeline on the exit code (see the budget/fail-open caveat above — give the scan enough budget to finish). Schedule `standard` scans nightly and `deep` scans for release candidates.
+
+---
+
+# Option B — Managed platform (no runner infra)
+
+No workflow file, no Docker, no LLM key. Two ways to use it:
+
+1. **PR-review app (zero code):** the user installs the Strix GitHub/GitLab/Bitbucket app and enables PR reviews for the repo in the app.strix.ai dashboard. Every PR is then reviewed automatically, with findings posted as PR comments. Nothing to add to the repo. This is the lowest-effort path — recommend it first when the user just wants PR gating.
+
+2. **API-triggered from any pipeline:** if you want to trigger from an existing pipeline (or a system without the SCM app), call the API with a token that has `pr_reviews:write` (or `scans:write`). Store the token as a CI secret; ask the user to create it at **Settings → API Access**. Example GitHub Actions step:
+
+   ```yaml
+   - name: Strix PR review (managed)
+     if: github.event_name == 'pull_request'
+     env:
+       STRIX_API_TOKEN: ${{ secrets.STRIX_API_TOKEN }}
+     run: |
+       curl -sS --fail https://app.strix.ai/api/v1/pr-reviews/start \
+         -H "Authorization: Bearer $STRIX_API_TOKEN" \
+         -H "Content-Type: application/json" \
+         -d "{\"repository_full_name\":\"${{ github.repository }}\",\"pr_number\":${{ github.event.pull_request.number }}}"
+   ```
+
+   To gate the build on results, poll the PR review / scan status and fail on unresolved criticals/highs. Full endpoints (PR reviews, scans, SARIF export, schedules for scheduled deep scans) are in the **managed-pentesting-with-strix** skill.
+
+Recommend Option B for most teams (no maintenance, central dashboard); use Option A when scans must stay entirely within your own infrastructure.

+# Find security vulnerabilities in code
+
+White-box security review with Strix: the agents read the source to build a model of routes, sinks, and authorization checks, then attempt real exploitation. Findings come with a proof-of-concept, so the output is a short list of proven issues rather than the hundreds of "potential" hits a pattern-matching scanner produces.
+
+Install, LLM setup, all flags, and the managed-cloud path are in the **penetration-testing-with-strix** skill.
+
+## Run it
+
+```bash
+# Local working tree
+strix -n -t ./ --scan-mode standard --max-budget 15
+
+# A GitHub repo directly
+strix -n -t https://github.com/org/app --max-budget 15
+
+# Monorepo: point at the service that matters, not the whole tree
+strix -n -t ./services/checkout --max-budget 20
+
+# Only what a branch changed (whole-repo review is wasteful on a large repo)
+strix -n -t ./ --scope-mode diff --diff-base origin/main --max-budget 10
+```
+
+A local path is mounted into the sandbox **writable**, so the agents can modify it. Run against a clean checkout.
+
+Two things sharply improve results:
+
+1. **Add a running instance of the app.** `-t ./ -t http://host.docker.internal:3000` lets the agents confirm exploitability against live behavior instead of reasoning about it statically — this is the difference between "this looks unsafe" and a validated finding. If nothing is running, static-only findings should be described as unconfirmed.
+2. **Scope the review.** Point at the risky subtree and say what matters:
+   ```bash
+   strix -n -t ./services/api --max-budget 15 \
+     --instruction "Focus on the authorization layer in src/auth and every route under src/routes/admin. Multi-tenant app: tenant id comes from the JWT. Flag any query that filters by object id without also filtering by tenant."
+   ```
+   Tenancy model, trust boundaries, and which inputs are attacker-controlled are things the agents cannot infer reliably — tell them.
+
+## Reviewing a pull request instead of the whole repo
+
+For diff-scoped review of a branch or PR (and blocking merges on findings), use **ci-security-scanning-with-strix** — it covers diff scoping, PR comments, and SARIF upload to GitHub code scanning. The managed platform can also review PRs directly via API (**managed-pentesting-with-strix**).
+
+## Read the results
+
+In `strix_runs/<run>/`: `penetration_test_report.md` (start here), `vulnerabilities/*.md` (one per finding, with PoC and remediation), `vulnerabilities.json` / `.csv`, `findings.sarif` (upload to code scanning), `run.json`.
+
+Before reporting to the user, open each finding and check the PoC actually demonstrates impact. Report file and line alongside the exploit so the fix is obvious.
+
+Exit `0` means nothing exploitable was proven in what was analyzed — not that the codebase is clean. Check `run.json` status and cost against `--max-budget`, and note which paths went unreviewed if the run was capped.
+
+## Complementary tooling
+
+This is exploit-validated review, not an exhaustive inventory. Keep a dependency scanner (SCA) and secret scanning in place for complete coverage of known-CVE dependencies and committed credentials; use this for the logic, authorization, and injection bugs those tools structurally cannot find.
+
+## Fix and verify
+
+Hand results to **fix-security-vulnerabilities-with-strix**: patch the root cause (the shared authorization helper, not the one route), then re-run Strix to prove the exploit no longer works.

+
+# Fix Strix findings and verify
+
+Turn validated Strix findings into minimal, correct fixes — and prove they work by re-scanning.
+
+## 1. Triage
+
+Get the findings from wherever the scan ran:
+
+- **OSS CLI** — artifacts in `strix_runs/<run-name>/`:
+  - `vulnerabilities/*.md` — one finding per file: description, severity, PoC steps or script, affected code locations, remediation guidance.
+  - `vulnerabilities.json` — the same findings as JSON (ids, severity, CWE/CVE, `code_locations` with `fix_before`/`fix_after` suggestions when available).
+- **Cloud (app.strix.ai)** — fetch the scan's `vulnerabilities[]` via `GET /api/v1/scans/{scanId}` (or `GET /api/v1/vulnerabilities` org-wide). Each carries `severity, cwe, endpoint, method, impact, technical_analysis, poc_description, poc_script_code` and, for code findings, `code_file`/`code_diff`/`code_before`/`code_after`. See the **managed-pentesting-with-strix** skill for auth.
+
+Order work by severity: critical → high → medium → low. Every Strix finding was validated with a working proof-of-concept, so do not dismiss findings as false positives without re-testing the PoC yourself.
+
+## 2. Fix
+
+For each finding:
+
+1. Reproduce it with the PoC from the finding file when feasible.
+2. Fix the root cause, not the specific payload (parameterize every query instead of blocking one string, and enforce authorization in the handler instead of hiding the endpoint).
+3. Prefer the framework's built-in defense (ORM parameterization, template auto-escaping, CSRF middleware, centralized authz) over ad-hoc sanitization.
+4. Keep the diff minimal and apply the repo's existing patterns. Finding files often include `fix_before`/`fix_after` snippets — use them as a starting point, not verbatim.
+
+Common finding classes and expected fixes: injection → parameterization/escaping at the sink; IDOR/broken access control → object-level authorization checks; SSRF → allowlist + block internal ranges; XSS → context-aware output encoding + CSP; secrets exposure → rotate the secret AND remove it from code/history; auth issues → fix the server-side check (never client-side).
+
+## 3. Verify by re-running Strix
+
+After fixing, re-scan scoped to the fixed area and confirm the finding is gone. Verify in whichever environment you scanned (or both):
+
+**OSS CLI:**
+```bash
+# Re-test just the changed files (fast). Resolve the repo's real default
+# branch instead of assuming origin/main (many repos use master/develop).
+# Avoid the current branch's own upstream as the base — its merge base with
+# HEAD would be HEAD, giving an empty diff and a falsely clean result.
+DIFF_BASE=$(git symbolic-ref --quiet --short refs/remotes/origin/HEAD 2>/dev/null)
+# origin/HEAD can be a dangling symbolic ref — keep it only if its target exists.
+git rev-parse --verify --quiet "$DIFF_BASE" >/dev/null 2>&1 || DIFF_BASE=""
+if [ -z "$DIFF_BASE" ]; then
+  for b in origin/main origin/master origin/develop; do
+    git rev-parse --verify --quiet "$b" >/dev/null && DIFF_BASE="$b" && break
+  done
+fi
+# No silent fallback: a guess like HEAD~1 would cover only the last commit of a
+# multi-commit fix branch. If no base resolves, ask the user for the base branch
+# (or use the focused --instruction verification below, which needs no diff base).
+[ -n "$DIFF_BASE" ] || { echo "Set DIFF_BASE to the branch your fix will merge into." >&2; exit 1; }
+strix -n -t ./ --scan-mode quick --scope-mode diff --diff-base "$DIFF_BASE" --max-budget 5
+
+# Or re-test with the original finding as focus (no diff base needed)
+strix -n -t ./ --instruction "Verify the SQL injection in app/api/search.py is fixed. Original PoC: <poc>" --max-budget 5
+```
+Exit codes: `2` = findings remain (read the new `strix_runs/<run>/vulnerabilities/` and iterate); `0` = clean **for what was analyzed**. Before trusting a `0`, confirm the run wasn't cut short — check `run.json` for a completed status and compare its `llm_usage.cost` with `--max-budget`: a hard budget stop leaves `status: "stopped"`, but a run that wrapped up on a budget warning records `"completed"` with partial coverage. Give verification enough budget to finish, and prefer re-running the specific PoC as the ground-truth signal.
+
+**Cloud:** rerun with the same config and re-poll, then confirm the finding no longer appears:
+```bash
+new_id=$(curl -sS "$BASE/scans/$scan_id/rerun" "${auth[@]}" -X POST | jq -r .scan_id)
+# poll GET /scans/$new_id until completed, then check its vulnerabilities[]
+```
+Or, if the cloud scan came from a repo/PR, trigger a fresh PR review on the fix branch (`POST /pr-reviews/start`). The platform also retests a single finding directly: `POST /api/v1/vulnerabilities/{vulnerabilityId}/retest`.
+
+- Also re-run the PoC manually when it is a simple request/script — fastest signal.
+- Run the project's own test suite to make sure the fix does not break behavior.
+
+## 4. Report
+
+Summarize per finding: severity, root cause, fix applied (file:line), verification result (re-scan clean / PoC no longer reproduces). Never include live secrets in the report; if a secret leaked, state that rotation is required.

+# Strix Cloud API (managed, no local infra)
+
+Use this when you want Strix's autonomous pentesting **without running Docker or an LLM yourself** — the scan runs on Strix's infrastructure and results are tracked in a team dashboard. This is the right choice in sandboxed/hosted agent and CI environments, for teams, and for scheduled/continuous testing (downloadable PDF/DOCX reports are an Enterprise-plan feature). For fully local, free, air-gapped, or BYO-LLM runs, use the open-source CLI in the **penetration-testing-with-strix** skill instead — both share the same engine and SARIF output, so you can mix them.
+
+Full reference: **[docs.app.strix.ai](https://docs.app.strix.ai)** · OpenAPI: `https://docs.app.strix.ai/openapi.json`
+
+## Setup
+
+- **Base URL:** `https://app.strix.ai/api/v1`
+- **Auth:** every request sends `Authorization: Bearer <token>`. Tokens are **org-scoped**.
+- **Get a token:** the user creates one in the dashboard at **Settings → API Access** (app.strix.ai). Ask them for it; never hardcode, log, or commit it. Store it in an env var or the CI secret store.
+- **Scopes (least-privilege):** assign only what the integration needs and rotate regularly:
+
+  | Scope | Grants |
+  |---|---|
+  | `scans:read` / `scans:write` | list/read/report scans · create/rerun/cancel scans |
+  | `vulnerabilities:read` / `:write` | read findings · update status & notes |
+  | `assets:read` / `:write` | read domains/repos · register/update them |
+  | `schedules:read` / `:write` | read schedules · create/trigger recurring scans |
+  | `pr_reviews:write` | trigger PR security reviews |
+  | `webhooks:read` / `:write` | manage webhook subscriptions |
+  | `tokens:write` | create/revoke API tokens |
+
+```bash
+export STRIX_API_TOKEN="<token>"
+BASE=https://app.strix.ai/api/v1
+auth=(-H "Authorization: Bearer $STRIX_API_TOKEN")
+```
+
+All examples use `jq` to parse JSON. Handle HTTP errors: `401` bad/expired token, `402` out of credits, `403` scope/plan-tier limit, `422` validation error.
+
+## 1. Register the target as an asset
+
+Scans run against **registered assets**, not raw URLs. Register once, then reuse the returned UUID.
+
+```bash
+# Domain (black-box / live target). Requires domain verification before external scanning.
+# asset_type must be one of: web_app | api | attack_surface.
+curl -sS "$BASE/domains" "${auth[@]}" -H "Content-Type: application/json" \
+  -d '{"domain":"staging.example.com","asset_type":"web_app"}' | jq '{id:.domain.id, status, reachable, verification}'
+
+# Repository (white-box / code review). `full_name` is "owner/name".
+# Send one repository object, or a bare JSON array for several — not an object
+# wrapping a "repositories" key (that is rejected with 400).
+curl -sS "$BASE/repositories" "${auth[@]}" -H "Content-Type: application/json" \
+  -d '[{"full_name":"org/app","provider":"github"}]' | jq '.repositories[] | {id, full_name}'
+```
+
+Look up existing assets instead of re-adding: `GET /domains`, `GET /repositories` (both `assets:read`, paginated with `?page=&limit=`).
+
+## 2. Launch a scan
+
+`POST /scans` (`scans:write`). Provide at least one target via `domain_ids`, `repository_ids`, or `internal_targets` (internal infra needs a network connector — see docs).
+
+```bash
+scan_id=$(curl -sS "$BASE/scans" "${auth[@]}" -H "Content-Type: application/json" -d '{
+  "engagement_type": "live_test",
+  "domain_ids": ["<domain-uuid>"],
+  "focus": "IDOR, auth bypass, SSRF",
+  "context": "Staging. Test account creds are configured as a test user.",
+  "notify_on_completion": true
+}' | jq -r .scan_id)
+echo "$scan_id"
+```
+
+Useful `CreateScanRequest` fields:
+
+| Field | Purpose |
+|---|---|
+| `engagement_type` | `live_test` (default), `code_review`, `internal_infra`, `compliance_pentest` |
+| `domain_ids` / `repository_ids` / `internal_targets` | targets (at least one) |
+| `domain_paths` / `repository_branches` | narrow to specific paths / branches |
+| `credentials` | authenticated scanning, incl. `mfa_method` (`totp`/`email_otp`/…) + `totp_secret` |
+| `headers` | extra HTTP headers (API keys, for example) for the target |
+| `focus` / `concerns` / `context` | steer the agents |
+| `upload_ids` | attach uploaded source/docs archives for white-box context |
+| `notify_on_completion` / `notification_emails` | email when done |
+
+Response is `{ scan_id, title, status }` with `status` = `pending`.
+
+## 3. Poll to completion
+
+`GET /scans/{scanId}` (`scans:read`). Status flow: `pending → running → completed` (or `failed` / `cancelled`). Poll on an interval — scans take minutes to hours. Do not block.
+
+```bash
+while :; do
+  s=$(curl -sS "$BASE/scans/$scan_id" "${auth[@]}" | jq -r .status)
+  echo "status=$s"; [[ "$s" =~ ^(completed|failed|cancelled)$ ]] && break
+  sleep 60
+done
+```
+
+## 4. Read findings
+
+The scan-detail response includes `executive_summary`, `methodology`, `recommendations`, a `findings` severity roll-up, and a `vulnerabilities[]` array. Each vulnerability carries `title, severity, status, cvss, cwe, endpoint, method, impact, technical_analysis, poc_description, poc_script_code`, and (for code findings) `code_file`/`code_diff`/`code_before`/`code_after`.
+
+```bash
+curl -sS "$BASE/scans/$scan_id" "${auth[@]}" \
+  | jq '["critical","high","medium","low","info"] as $order
+       | .vulnerabilities
+       | sort_by(.severity as $s | $order | index($s))
+       | .[] | {title, severity, endpoint, cwe}'
+```
+
+Cloud severities are `critical | high | medium | low` and statuses are `open | in_progress | fixed | ignored`. Sort by an explicit severity order rather than `sort_by(.severity)`, which sorts alphabetically (critical, high, low, medium).
+
+Org-wide triage across scans: `GET /vulnerabilities` (`vulnerabilities:read`; filter by severity/status). Update triage state with the vulnerabilities `:write` endpoints. To remediate, hand off to the **fix-security-vulnerabilities-with-strix** skill.
+
+## 5. Export & report
+
+```bash
+# SARIF 2.1.0 for GitHub code scanning / ASPM ingestion
+curl -sS "$BASE/scans/$scan_id/sarif" "${auth[@]}" -o findings.sarif
+
+# Report. The format and file type are query params (`Accept` is ignored):
+#   format=technical (default) | retest | attestation | executive_summary
+#   type=pdf (default) | docx
+# Any report download requires the Enterprise plan; formats beyond `technical`,
+# DOCX, and white-label branding are Enterprise-only too. Scan must be completed.
+curl -sS "$BASE/scans/$scan_id/report?format=technical&type=pdf" "${auth[@]}" -o strix-report.pdf
+```
+
+## 6. PR reviews
+
+Trigger an automated security review of a pull request (`pr_reviews:write`); results appear as PR comments and in the dashboard:
+
+```bash
+curl -sS "$BASE/pr-reviews/start" "${auth[@]}" -H "Content-Type: application/json" \
+  -d '{"repository_full_name":"org/app","pr_number":123}'
+```
+
+List/inspect via `GET /pr-reviews` and `GET /pr-reviews/{id}`. Repo-level PR-review behavior is configured with the repository-settings endpoint.
+
+## 7. Continuous testing (schedules & webhooks)
+
+- **Schedules** (`schedules:write`, Pro plan): create recurring scans and trigger them on demand — the managed equivalent of a cron-driven CLI loop.
+- **Webhooks** (`webhooks:write`): subscribe to pentest/vulnerability lifecycle events such as `scan.completed` and `vulnerability.created` to push results into Slack, ticketing, or your own pipeline instead of polling.
+
+See the schedules and webhooks sections at [docs.app.strix.ai](https://docs.app.strix.ai) for payloads.
+
+## Safety
+
+Only scan assets the user's organization owns or is authorized to test. External domain scans require verification (DNS/file/meta-tag) enforced by the platform — do not try to bypass it.

+# Test against the OWASP Top 10
+
+The OWASP Top 10 is a taxonomy of risk categories, not a test suite — "OWASP Top 10 testing" means exercising each category against the real application and reporting what's actually exploitable. Strix's agents do the exploitation; this skill covers running it category-by-category and reporting coverage honestly.
+
+**Use the current edition: [OWASP Top 10:2025](https://owasp.org/Top10/)** (8th installment, superseding 2021). Ask the user before targeting an older edition — some compliance checklists still reference 2021, and a report labelled with the wrong edition is misleading. Key differences from 2021: **SSRF is folded into A01**, **A03 Software Supply Chain Failures** expands the old "Vulnerable and Outdated Components", and **A10 Mishandling of Exceptional Conditions** is new; A02 Security Misconfiguration moved 5→2.
+
+Install, LLM setup, and the managed-cloud alternative: **penetration-testing-with-strix**.
+
+## What is and is not testable by an agent
+
+Be straight with the user about this — claiming a clean sweep of all ten is misleading.
+
+| Category (2025) | Coverage |
+|---|---|
+| A01 Broken Access Control (incl. SSRF) | **Strong** — cross-user/tenant access, privilege escalation, IDOR, and SSRF (including blind, via out-of-band callbacks) are all exploit-validated. Needs two accounts plus a privileged one to prove the authorization half. |
+| A02 Security Misconfiguration | **Strong** — debug endpoints, verbose errors, permissive CORS, missing hardening, default credentials, exposed admin surfaces. |
+| A03 Software Supply Chain Failures | **Partial** — version fingerprinting, and vulnerable/outdated dependency review when source is supplied. Build-system and distribution-infrastructure compromise (the broader half of this category) is out of scope for a runtime scan — pair with SCA plus build-provenance controls. |
+| A04 Cryptographic Failures | **Partial** — transport config, unencrypted data in transit, secrets and tokens leaked in responses. At-rest crypto and key management need source or infra review. |
+| A05 Injection | **Strong** — SQL/NoSQL/command/template injection and XSS, exploit-validated. |
+| A06 Insecure Design | **Partial** — business-logic abuse (price/quantity tampering, workflow skipping, race conditions) is found where reachable; design intent still needs human review and threat modelling. |
+| A07 Authentication Failures | **Strong** — auth bypass, weak session/token handling, password-reset and MFA flaws. |
+| A08 Software or Data Integrity Failures | **Partial** — insecure deserialization and unsigned-update paths where reachable; CI/CD trust boundaries are not runtime-testable. |
+| A09 Security Logging & Alerting Failures | **Not testable from outside** — requires reviewing the logging and alerting pipeline. State this rather than reporting it as passed. |
+| A10 Mishandling of Exceptional Conditions | **Partial** — agents actively probe error handling and fail-open behavior (malformed input, forced errors, race and timeout conditions) and report what leaks or bypasses a control; exhaustive coverage of internal error paths needs source review. |
+
+For APIs, run the same exercise against the **OWASP API Security Top 10 (2023)** — API1 BOLA, API3 Broken Object Property Level Authorization (2019's excessive data exposure + mass assignment merged), API5 broken function-level authorization — using the **api-security-testing** skill.
+
+## Run it
+
+Maximum category coverage comes from giving the agents both the source and a running instance, plus credentials at two privilege levels:
+
+```bash
+strix -n \
+  -t https://github.com/org/app \
+  -t https://staging.example.com \
+  --scan-mode deep --max-budget 30 \
+  --instruction "OWASP Top 10:2025 assessment. Cover every category systematically and map each finding to its 2025 category id.
+Accounts: userA@example.com/<pw> (org 1), userB@example.com/<pw> (org 2), admin@example.com/<pw>.
+Prioritise A01 (cross-org access, privilege escalation, SSRF), A02, A05, A07, A10.
+Out of scope: /billing/*, outbound email."
+```
+
+- `--scan-mode deep` matters here: systematically walking ten categories is not a quick scan.
+- Without a second account, A01 results are structurally incomplete — say so in the report rather than leaving it implied.
+- Need an auditor-facing PDF? Run it through the managed platform and pull the technical report (**managed-pentesting-with-strix**).
+
+## Report honestly
+
+From `strix_runs/<run>/`, group `vulnerabilities/*.md` by category and state, per category: what was attempted, what was proven, and what could not be assessed (A09 always; A03/A04/A06/A08/A10 partially). Label the report with the edition used. Verify each PoC yourself before it goes in front of the user.
+
+A `0` exit code means nothing exploitable was proven **in what was analyzed** — check `run.json` status and cost against `--max-budget`; a budget-capped run is not a completed assessment.
+
+## Then fix and re-test
+
+Remediate with **fix-security-vulnerabilities-with-strix** and re-run to prove each exploit is closed. For ongoing coverage as the app changes, gate pull requests using **ci-security-scanning-with-strix**.

+# Run a Strix pentest
+
+Strix runs autonomous AI pentesting agents that dynamically exploit a target and only report findings validated with a working proof-of-concept. There are **two ways to run it, built on the same engine and producing the same findings** — pick per situation, and mix them freely:
+
+- **Open-source CLI** (self-hosted) — runs on your machine in a Docker sandbox with your own LLM key. Free, fully local, BYO-LLM, air-gap capable. Docs: [docs.strix.ai](https://docs.strix.ai).
+- **Cloud API** (managed) — runs on Strix's infrastructure via `https://app.strix.ai/api/v1`. No Docker, no LLM key, no local compute; adds team dashboards, scheduling, PR reviews, downloadable PDF/DOCX reports (Enterprise plan), and internal-network connectors. Docs: [docs.app.strix.ai](https://docs.app.strix.ai). Full workflow in the **managed-pentesting-with-strix** skill.
+
+## Which one? (decide, do not default)
+
+Choose honestly based on the situation — neither is "better":
+
+| Situation | Prefer |
+|---|---|
+| No Docker available, or a sandboxed/hosted agent/CI environment | **Cloud** |
+| User has no LLM key / does not want to pay per-token or manage models | **Cloud** |
+| Team visibility, shareable dashboard, scheduled/continuous scans, PR reviews, downloadable PDF/DOCX report (Enterprise) | **Cloud** |
+| Scanning internal/private infrastructure not reachable from your machine | **Cloud** (network connector) |
+| Source must never leave local infra (privacy/air-gap), or fully offline | **OSS CLI** |
+| Free / one-off / local dev-loop scan, Docker already present | **OSS CLI** |
+| BYO or self-hosted LLM, or a specific model not offered by the platform | **OSS CLI** |
+| CI: runner already has Docker and you want a self-contained gate | **OSS CLI** |
+| CI: no Docker, or you want results tracked centrally | **Cloud** |
+
+**Mix them:** use the OSS CLI for the fast local dev-loop while writing/fixing code, and the Cloud for the authoritative, team-visible scan + report + tracking; or gate PRs with the OSS CLI in CI while the Cloud runs scheduled deep scans and PR reviews across the org. Both emit the same SARIF 2.1.0, so findings line up across environments.
+
+If unsure and the user has (or will create) an app.strix.ai account, prefer **Cloud** — it avoids all local-infra friction. If they want zero signup / full local control, use the **OSS CLI**.
+
+---
+
+# Option A — Open-source CLI (self-hosted)
+
+## Prerequisites
+
+1. **Docker running** — check with `docker info`. The first scan pulls the sandbox image automatically.
+2. **Strix installed** — check with `strix --version`. Install if missing:
+   ```bash
+   curl -sSL https://strix.ai/install | bash   # or: pipx install strix-agent
+   ```
+3. **LLM configured** — two environment variables:
+   ```bash
+   export STRIX_LLM="openai/gpt-5.4"      # any LiteLLM model id (openai/..., anthropic/..., openrouter/...)
+   export LLM_API_KEY="<provider api key>"
+   ```
+   Ask the user for these if unset. Never hardcode or commit keys.
+
+## Running a scan
+
+Always use `-n` (non-interactive/headless) — the default TUI blocks agents. Always set `--max-budget` unless the user says otherwise.
+
+```bash
+# Local code (white-box)
+strix -n -t ./ --scan-mode standard --max-budget 10
+
+# Deployed app / API (black-box)
+strix -n -t https://staging.example.com --max-budget 20
+
+# Repo + deployed app together (best coverage)
+strix -n -t https://github.com/org/app -t https://staging.example.com
+
+# Focused testing with credentials or scope hints
+strix -n -t https://app.example.com \
+  --instruction "Use credentials user@example.com:pass123. Focus on IDOR and auth bypass."
+
+# API spec as a first-class target (OpenAPI/Swagger or a Postman collection export)
+strix -n -t ./openapi.yaml -t https://api.staging.example.com
+
+# Many targets from a file, one per line
+strix -n --target-list ./targets.txt --max-budget 30
+
+# Give the agents a file to work with (wordlist, spec, notes) without making it a target
+strix -n -t https://staging.example.com --workspace-file ./wordlist.txt --max-budget 20
+```
+
+A local path passed with `-t` is mounted into the sandbox **writable** — the agents can read and modify it, so point at a clean checkout, not uncommitted work you care about.
+
+Key flags:
+

+|---|---|
+| `-t, --target` | URL, repo URL, local path, domain, IP, OpenAPI/Postman spec, or `postman://<uuid>`. Repeatable. |
+| `--target-list PATH` | File of targets, one per line (`#` comments allowed). Repeatable, combines with `-t`. |
+| `-n, --non-interactive` | Headless, exits on completion. Required for agents. |
+| `-m, --scan-mode` | `quick` (minutes) / `standard` (~30 min) / `deep` (hours, default). |
+| `--instruction` / `--instruction-file` | Credentials, focus areas, scope rules. |
+| `--workspace-file PATH[:DEST]` | Place a file from this machine into `/workspace` read-only before the scan, for a wordlist, a spec, or notes. Repeatable. |
+| `--max-budget USD` | Hard LLM spend cap; scan wraps up cleanly at the limit. |
+| `--max-turns N` | Per-agent turn cap (default 500). |
+| `--resume RUN_NAME` | Resume a prior run from `strix_runs/`, with its agent history and targets. Cannot be combined with `-t`. |
+| `--scope-mode` | For code targets: `auto` (diff-scope in CI/headless), `diff` (force changed files only), `full` (whole tree). |
+| `--diff-base REF` | Branch or commit that `diff` scope compares against. Defaults to the repo's default branch. |
+
+Scans take minutes (`quick`) to hours (`deep`). Run them in the background and poll for completion rather than blocking.
+
+### Exit codes (headless)
+
+- `0` — finished with no validated vulnerabilities **in what was analyzed**
+- `1` — fatal error (missing env vars, Docker down, bad config)
+- `2` — vulnerabilities found
+
+A `0` is not proof of full coverage: if `--max-budget`/`--max-turns` is reached before the scan completes, it wraps up early and still exits `0`. When you need assurance the scan finished, give it enough budget and check `strix_runs/<run>/run.json`: a hard budget stop leaves `status: "stopped"`, but an agent that wrapped up early on a budget *warning* still calls `finish_scan` and records `"completed"` — so also sanity-check the run's cost against `--max-budget` and the report's stated coverage before treating a clean result as full coverage.
+
+### Reading results
+
+Artifacts land in `strix_runs/<run-name>/`:

+# Option B — Cloud API (managed, no local infra)
+
+Full details, asset registration, polling, reports, PR reviews, schedules, and webhooks are in the **managed-pentesting-with-strix** skill. Minimal launch-and-poll:
+
+```bash
+export STRIX_API_TOKEN="<token>"   # org-scoped bearer, from Settings → API Access at app.strix.ai
+BASE=https://app.strix.ai/api/v1
+
+# 1. Launch a scan against an already-registered domain/repo asset
+scan_id=$(curl -sS "$BASE/scans" \
+  -H "Authorization: Bearer $STRIX_API_TOKEN" -H "Content-Type: application/json" \
+  -d '{"engagement_type":"live_test","domain_ids":["<domain-uuid>"]}' | jq -r .scan_id)
+
+# 2. Poll until terminal (pending → running → completed/failed/cancelled)
+curl -sS "$BASE/scans/$scan_id" -H "Authorization: Bearer $STRIX_API_TOKEN" | jq '.status'
+
+# 3. Read validated findings from the scan detail's `vulnerabilities[]`, or export SARIF
+curl -sS "$BASE/scans/$scan_id/sarif" -H "Authorization: Bearer $STRIX_API_TOKEN" -o findings.sarif
+```
+
+Ask the user to create the token (and register the target as a domain/repository asset) if they have not. If Docker/local prerequisites are not already satisfied, use this path instead of trying to install infra.
+
+---
+
+## Reporting & next steps
+
+Summarize findings by severity (critical/high/medium/low/info) and include the PoC evidence. To remediate and verify fixes (via either path), use the **fix-security-vulnerabilities-with-strix** skill. To wire scanning into CI/CD, use the **ci-security-scanning-with-strix** skill.
+
+## Safety
+
+Only scan targets the user owns or is authorized to test. The Cloud platform enforces domain verification before external scans; for the OSS CLI, confirm authorization yourself if the target looks like third-party infrastructure.

+description: Pentest a web app or website end to end — black-box testing of a live URL, staging environment, or local dev server that finds and exploits real vulnerabilities (auth bypass, broken access control, IDOR, injection, XSS, SSRF, business logic) and proves each one with a working proof-of-concept instead of a signature match. Runs with Strix, either the self-hosted open-source CLI or the managed app.strix.ai cloud. Use when the user asks to pentest, hack, security-test, or audit their web app, website, web application, or staging site.

+
+# Pentest a web application
+
+Black-box (and optionally source-assisted) penetration testing of a running web app with Strix's autonomous agents. Every reported finding is validated with a working exploit, so there are no signature-based false positives to triage.
+
+Install, LLM setup, all CLI flags, and the managed-cloud alternative are covered in the **penetration-testing-with-strix** skill — read it if the target is not a running web app, or if `strix --version` fails. This skill is the web-app-specific workflow.
+
+## 1. Confirm authorization and scope
+
+Before running anything, establish:
+
+- **The target is the user's** (or they are explicitly authorized to test it). Never pentest a third-party site on a hunch.
+- **Which environment.** Prefer staging over production; agents send real exploit payloads and will create/modify data.
+- **Out-of-scope paths** — payment flows, mass-email endpoints, admin destructive actions, third-party SSO providers.
+- **Credentials.** Most real vulnerabilities live behind login. Without a test account, the agents only ever see the marketing surface.
+
+Ask for anything missing rather than guessing.
+
+## 2. Run the scan
+
+```bash
+strix -n -t https://staging.example.com --max-budget 20 \
+  --instruction "Test account: qa@example.com / <password>. In scope: /app/*, /api/*. Do not touch /billing or send email. Focus on access control between the two seeded orgs."
+```
+
+Notes that matter for web apps specifically:
+
+- **Give it credentials via `--instruction`** (or `--instruction-file` for anything long), including how to log in if the flow is unusual (magic link, SSO, MFA-exempt test user).
+- **Two accounts beat one.** Multi-tenant IDOR and broken-access-control bugs — consistently the highest-impact class in web apps — can only be proven when the agent can attempt cross-account access.
+- **Add the repo for white-box depth** when you have the source: `-t https://github.com/org/app -t https://staging.example.com` (or a local path). Source access materially improves coverage of business-logic and authorization flaws.
+- **Localhost works.** Point at `http://host.docker.internal:3000` (Docker Desktop) so the sandbox can reach a dev server on the host.
+- `--scan-mode quick` for a fast dev-loop pass, `standard` (~30 min) for a normal review, `deep` for pre-release assurance. Always set `--max-budget`.
+
+For a hosted run with no Docker/LLM key, or when the user wants a shareable dashboard and an auditor-ready PDF, use the cloud path in **managed-pentesting-with-strix** instead — same engine, same findings.
+
+## 3. Review results
+
+Read `strix_runs/<run>/penetration_test_report.md` first, then per-finding files in `vulnerabilities/`. Each contains the PoC — re-run it yourself to confirm before reporting to the user.
+
+Exit codes: `0` no validated vulns in what was analyzed, `2` vulnerabilities found, `1` fatal error. A `0` is not proof of full coverage — if the budget or turn cap was hit the scan wraps up early, so check `run.json` status and cost against `--max-budget` before calling the app clean.
+
+## 4. Fix and verify
+
+Hand findings to the **fix-security-vulnerabilities-with-strix** skill: patch the root cause, then re-run Strix against the same target to prove the exploit no longer works. Re-testing is the only reliable confirmation a fix landed.
+
+To keep the app tested on every change rather than once, wire Strix into CI with **ci-security-scanning-with-strix**.

 - Answering a user question: put the answer in respond_to_user's message. Do not write the answer as plain text and then fall silent — that does not reach a stopping point, it just triggers a continuation nudge.
+- If all you want to do is reply and stop, that whole turn is ONE respond_to_user call carrying the answer. Do not write the answer as text and then call respond_to_user as well: the user reads it twice.
+- If you do end a turn on plain text and the nudge arrives, your words already reached the user. Do not restate them: call respond_to_user with NO message to simply wait, or with only whatever you still need to add.
 - You may include brief explanatory text before a tool call, and you can narrate while you work — plain text is shown to the user as you go. Narrating is free; respond_to_user is specifically the act of WAITING for the user, so do not call it just to give a status update.
 - Respond naturally when the user asks questions or gives instructions.
 - While actively working on a task, every turn should carry exactly one tool call — use think to plan, the appropriate tool to act, and respond_to_user only when you genuinely need the user.

 - Independent verification through subagent
 - Document complete attack chain
 - Keep going until you find something that matters
+- CLOSURE DISCIPLINE: every candidate you open ends in exactly one explicit state — `confirmed` (working PoC, or a complete source→control→sink→impact trace that is reachable), `ruled_out` (you can name the SPECIFIC control, at a location, that runs on every attacker-reachable path before the sink), or `open_proof_gap` (plausible, unconfirmed, and you could NOT name such a control). "I moved on" is not a closure state. Silently dropping an uncertain candidate is mislabelling an `open_proof_gap` as `ruled_out` and is how real bugs get missed.
+- Missing information is NOT proof of safety: no caller found, can't tell if deployed/exposed, couldn't stand up the service, build failed — each is an `open_proof_gap`, never a reason to mark a candidate clean. Difficulty is a reason to defer, not to suppress.
+- COVERAGE: record every surface you assess with `record_coverage` (surface + risk area + outcome + evidence), including the ones that came back clean — a report that only lists findings cannot say what was reviewed and cleared. Use the `needs_follow_up` outcome for anything left in an `open_proof_gap` state, and carry the same items up in `agent_finish(open_items=[...])`. The ledger is shared and mutable: when you resolve a surface another agent left open — or find that a closed one is not — move that entry with `update_coverage` instead of recording a second one for the same surface. The root agent reconciles all of it via `list_coverage` before `finish_scan`.
+- THREAT MODEL: before you start testing, call `get_threat_model` on the target you were pointed at — it is the scan's shared answer to who the attacker is, where the trust boundaries sit, and what counts as critical here, and it is cached per target rather than per scan. Read it instead of re-deriving trust boundaries yourself; where your testing disproves it — a boundary it calls trusted turns out to be attacker-reachable, a role it did not know about, a host or endpoint it never listed — record that with `amend_threat_model` so the agents after you inherit the correction. Amending is not optional politeness: a model nobody corrects turns the first agent's guesses into everyone's assumptions.
+- Before filing any report, run the counterevidence pass: argue the strongest case AGAINST the finding, record what you found in the `counterevidence` field, set `confidence` honestly (a static-only trace you couldn't execute is at best `medium`), and state what evidence would change the severity. See the counterevidence and severity-calibration knowledge above.
 - A vulnerability is ONLY considered reported when a reporting agent uses create_vulnerability_report (or create_dependency_report for known-CVE dependency/supply-chain findings) with full details. Mentions in agent_finish, finish_scan, or generic messages are NOT sufficient
 - Reporting and fixing are ONE step, not two: when source is available, the reporting agent derives the concrete fix and files it INLINE via create_vulnerability_report (`code_locations` with `fix_before`/`fix_after` + `fix_pr_body`) — the report is not complete without it. Do NOT report first and then spawn a separate downstream agent to re-derive and re-apply the same patch; that just re-does the analysis and wastes tokens. (Do not silently patch a finding WITHOUT filing a report — the report, with its embedded fix, is the deliverable.)
 - DEDUPLICATION: The create_vulnerability_report tool uses LLM-based deduplication. If it rejects your report as a duplicate, DO NOT attempt to re-submit the same vulnerability. Accept the rejection and move on to testing other areas. The vulnerability has already been reported by another agent
 - REVIEWING FILED FINDINGS (orchestrator/root agent): use list_reports to see every vulnerability filed so far in this scan (by any agent, root or child) — metadata-first with per-severity counts — and get_report to read one finding in full by its id. These are read-only orchestration tools: the root agent uses them to track coverage, avoid dispatching work on already-covered ground, assemble the finish_scan executive summary, and reason about attack-chaining across confirmed findings. Leaf/specialist agents should NOT call them — just do your assigned testing and file findings. Each entry shows which agent filed it (agent_name), and your own entries are flagged by_you. list_notes/get_note do the same for notes.
+
+STATE & COORDINATION TOOLS (when and how):
+Every one of these tools writes to state the rest of the scan reads. Reaching for the tool is not optional bookkeeping — the agent after you sees your state, not your reasoning, so state you never wrote is context the scan permanently loses.
+- PLAN — `think`: use before any non-trivial or multi-step move to reason through approach, uncertainty, or what to do next. NOT for acknowledgements, summaries, or as filler before a final answer.
+- SKILLS — `load_skill`: the skills matching your task are already inlined below under `<specialized_knowledge>`; `<available_skills>` lists the rest by name. When you are about to test a vuln class, protocol, tool, or framework whose skill is not already inlined, `load_skill` it FIRST and follow it, rather than guessing payloads or tool syntax from memory.
+- TODOS — `create_todo` / `list_todos` / `update_todo` / `mark_todo_done` / `mark_todo_pending` / `delete_todo`: your own working checklist for a multi-step task. Create todos when your task has several distinct steps so nothing is dropped across a long run; mark them done as you finish. This is private working memory — use `notes` for anything another agent needs.
+- NOTES — `create_note` / `list_notes` / `get_note` / `update_note` / `delete_note`: the scan's shared scratchpad, visible to every agent. Write a note for a durable cross-agent fact that is not a finding and not coverage — a working credential set, a discovered endpoint inventory, an enumerated tenant list, a rate-limit quirk the next agent needs. `update_note` to keep a living inventory current; `delete_note` only for something now wrong or superseded. Check `list_notes`/`get_note` before recon work so you build on what is already mapped instead of redoing it.
+- THREAT MODEL — `get_threat_model` / `amend_threat_model` / `save_threat_model`: covered above. `save_threat_model` REPLACES the whole document and clears amendments, so it is for establishing the baseline or folding amendments in (normally root) — to correct part of an existing model, `amend_threat_model` instead.
+- COVERAGE — `record_coverage` / `update_coverage` / `list_coverage`: covered above. One row per surface+risk; correct an existing row with `update_coverage`, never a second `record_coverage`.
+- RESEARCH — `web_search`: pull fresh, target-specific external knowledge — latest bypasses, WAF evasions, DB-/framework-specific syntax, CVE and advisory detail — before falling back to memorized payloads, and refresh payload corpora mid-spray.
+- SPAWN WORK — `create_agent`: delegate a focused subtask to a specialist child (see the multi-agent rules below for when to spawn and how to scope it). Give it the target to model against and what is already known.
+- TRACK CHILDREN — `view_agent_graph`: your live map of every agent and its status. Call it before spawning (to confirm no existing agent already covers the scope) and before finishing (to confirm no child is still running).
+- STEER CHILDREN — `send_message_to_agent`: send a running child new information, a course correction, or a request to wrap up, without killing it. Use it to answer a child's question or narrow its scope mid-run.
+- BLOCK ON CHILDREN — `wait_for_agents`: block until named children report back when your next move genuinely depends on their results. If you can keep making progress in parallel, keep working instead of waiting.
+- CANCEL CHILDREN — `stop_agent`: gracefully cancel a child whose work is redundant, misdirected, or no longer needed. Prefer `send_message_to_agent` to redirect a child that is merely off-track; reserve `stop_agent` for work that should not continue at all.
+- FINISH — subagents call `agent_finish` (with `open_items=[...]` for anything left unresolved); the root agent calls `finish_scan` exactly once, only after every child is wrapped up and coverage is reconciled. `agent_finish`/`finish_scan` are handoffs, not reporting channels — a vulnerability is reported only via `create_vulnerability_report`/`create_dependency_report`.

+description: Closure discipline for security findings — what counts as proof of safety, what does not, and how to record an unresolved candidate instead of silently dropping it
+---
+
+# Counterevidence and Closure Discipline
+
+Proving a bug is real is only half the job. The other half is proving a
+candidate is *not* real — and that half is where both false positives and
+false negatives come from.
+
+This skill governs how you close a candidate. It applies to every
+candidate you open, whether it came from a scanner, a code read, a crawl,
+or a hunch.
+
+## Three Closure States
+
+Every candidate you open ends in exactly one of these. There is no fourth
+state, and "I moved on" is not one of them.
+
+**1. `confirmed`** — you have a working PoC or, in white-box, a complete
+source → control → sink → impact trace plus evidence the path is
+reachable. File it with `create_vulnerability_report`.
+
+**2. `ruled_out`** — you can name the **specific control** that makes the
+code safe, at a specific location, and you have checked that the control
+actually runs on the attacker's path. "Named control" means you can
+complete this sentence with concrete detail: *"This is safe because
+`<control>` at `<file:line or observed behavior>` `<does what>` before
+`<sink>`, on every path an attacker can reach."* If you cannot complete
+that sentence, you are not in `ruled_out`.
+
+**3. `open_proof_gap`** — the candidate is plausible, you could not
+confirm it, and you also could not name a control that rules it out. This
+is a legitimate, expected outcome. Record it with
+`record_coverage(outcome="needs_follow_up")`, carry it up in
+`agent_finish(open_items=[...])`, and reflect it in `counterevidence` /
+`confidence_rationale` if you file a related report. Do **not** convert
+it to `ruled_out` to tidy up your worklist.
+
+The failure mode this exists to prevent: an agent reads code, feels
+uncertain, and quietly closes the candidate. That is an
+`open_proof_gap` being mislabelled as `ruled_out`, and it is how real
+vulnerabilities get missed.
+
+## What Does NOT Rule Out a Candidate
+
+Each of these is a common, plausible-sounding reason to drop a candidate.
+None of them is sufficient on its own.
+
+**Generic trust in a library or helper.** "It uses a well-known
+sanitizer / the framework escapes this / the ORM handles it" is not
+counterevidence. You must confirm *that* call, with *those* arguments, in
+*that* context. Escaping helpers are context-specific: an HTML escaper
+does nothing in a JS or attribute context, a SQL identifier quoter is not
+a value quoter, and a path joiner is not a containment check.
+
+**A control that runs on a different path.** Middleware, a decorator, or
+a guard that protects the common route does not protect a sibling route,
+an internal caller, a batch/async job, or an admin alias that reaches the
+same sink. Check the specific path.
+
+**A control that runs at the wrong time.** Validation *before* a
+redirect, canonicalization *after* a path is already materialized, a
+containment check *after* extraction, or an ownership check *after* the
+object was already fetched and returned — these are ordering bugs, not
+controls. Establish that the control runs before the dangerous effect.
+
+**A control that can fail open.** Hardening flags set inside a
+`try`/`except` that swallows failures, a parser feature that a caller can
+override, a factory or config object supplied by the caller, or a
+allow-list that is empty by default — all leave the candidate alive.
+
+**A safe sibling.** If one call site is correctly guarded, that says
+nothing about the other call sites of the same helper. Never let a safe
+instance close a vulnerable one, and never collapse multiple instances
+into one candidate just because they share a root cause — each reachable
+instance stands or falls on its own.
+
+**Missing information.** "I could not find a caller", "I could not tell
+if this is deployed", "I could not determine whether this route is
+exposed", "I could not stand up the service" — every one of these is an
+`open_proof_gap`, not proof of safety. Missing evidence is missing
+evidence; it is not evidence of absence.
+
+**Difficulty.** "The build failed", "it needs credentials I don't have",
+"the service mesh isn't available" are reasons to record a proof gap and
+move on to the next candidate — not reasons to mark it clean. Do not let
+one hard environment setup consume the budget you need for sibling
+candidates.
+
+**Operator configurability.** "An operator *could* configure a filter",
+"this is a documented feature", "it's off by default" are not controls.
+What ships and what is reachable is what matters.
+
+**Being internal.** Internal-only, admin-only, or authenticated-only
+reduces severity — it does not make the finding unreal. Downgrade it;
+do not delete it.
+
+## Recording Closure
+
+Closure is only useful if it is written down. Every surface you assess
+gets a `record_coverage` entry:
+
+- `confirmed` → outcome `reported`, once the report is filed.
+- `ruled_out` → outcome `ruled_out`, with the named control in
+  `evidence`. If you cannot name it, this is not `ruled_out`.
+- `open_proof_gap` → outcome `needs_follow_up`, with the specific gap in
+  `evidence`.
+- Tested thoroughly with nothing to show for it → `no_issue_found`.
+- The risk cannot apply to this surface at all → `not_applicable`, with
+  the reason.
+
+A scan that records only findings cannot tell the reader what was
+reviewed and cleared, which makes every clean area indistinguishable
+from an unvisited one.
+
+Closure is not permanent. The ledger is shared across every agent, and
+a surface someone left at `needs_follow_up` is an invitation: if you
+had the credentials, the running service, or the reachability proof
+they lacked, move their entry with `update_coverage` rather than
+recording a parallel one. This runs both ways — a `ruled_out` whose
+named control does not cover the path you just found goes back to
+`reported` or `needs_follow_up`, with what changed in `evidence`. The
+previous state is kept as history, so correcting the record costs
+nothing and leaving it wrong costs a finding.
+
+## What DOES Rule Out a Candidate
+
+- You executed the attack and it demonstrably failed, and you understand
+  *why* it failed (not just that the response was a 403).
+- You can point at the control, at a location, and show it runs on every
+  attacker-reachable path to the sink, before the effect, without a
+  fail-open branch.
+- The sink is not actually dangerous in this context, and you can say
+  what makes it inert.
+- The input is not actually attacker-controlled, and you traced it to a
+  trusted origin rather than assuming it.
+
+Negative controls make a `ruled_out` much stronger: send the payload that
+*should* work if the bug were real, and show it is blocked, while a
+benign variant succeeds. That distinguishes "the control works" from "the
+endpoint is broken/unreachable for unrelated reasons".
+
+## Before You File a Report
+
+Run this pass on every finding before calling
+`create_vulnerability_report`:
+
+1. **Argue the other side.** Spend real effort building the strongest
+   case that this is *not* exploitable, or not as severe as you think.
+   Look for the guard you might have missed, the deployment context that
+   constrains it, the precondition you assumed.
+2. **Record what you found** in `counterevidence`. If you found a real
+   constraint, say what it is and why it does not neutralize the finding.
+   If you genuinely found nothing, say what you checked — "no input
+   validation, WAF, or authorization check was found on this path; tested
+   both authenticated and unauthenticated" — not just "none".
+3. **Set `confidence` honestly.** A working PoC against a live target is
+   `high`. A complete static trace you could not execute is at best
+   `medium`, and `confidence_rationale` must name the gap. Do not inflate
+   confidence to make a finding look better; an accurate `medium` is far
+   more useful to the reader than a `high` that does not survive triage.
+4. **State what would move the severity** in `severity_change_conditions`
+   — the one concrete piece of evidence that would raise or lower it
+   (e.g. "confirmation that this route is exposed to unauthenticated
+   internet traffic would raise this to critical").
+
+## Reporting an Unconfirmed Candidate
+
+Dynamic proof is the standard. But when you have a complete
+source → control → sink → impact trace and runtime reproduction is
+genuinely out of reach (no credentials, unavailable internal services, a
+build that cannot run in the sandbox), a static-only finding is still
+reportable — at `confidence: medium` or `low`, with the missing runtime
+proof named explicitly in `confidence_rationale`.
+
+What is **not** acceptable is a scanner hit with no trace, a "this
+pattern is usually dangerous" claim, or a finding where you never
+identified the attacker-controlled input. Those are not proof gaps, they
+are non-findings.
+
+If you are unsure whether a candidate clears this bar: it clears it if
+you can name the input, the path, the missing or broken control, and the
+effect. It does not if any one of those is a guess.

+description: How to verify a proposed code fix before shipping it — the ordered gates, what disqualifies a fix, and when to withhold the suggestion instead
+---
+
+# Fix Verification
+
+When you attach `fix_before` / `fix_after` to a code location, you are not
+writing advice. You are writing a suggestion block that a reviewer can
+apply with one click, straight into their codebase. An unverified fix is
+worse than no fix: it converts your uncertainty into their merged commit.
+
+This skill covers what you must establish before that happens.
+
+## Judge in This Order
+
+1. The current state is correctly classified — vulnerable, already safe,
+   or unproven.
+2. The fix completely closes the broken security boundary.
+3. Legitimate behavior and compatibility are preserved.
+4. The relevant repository checks pass.
+5. The change follows the repository's own conventions.
+6. The patch contains only what properties 1–5 require.
+
+**Never trade an earlier property for a later one.** A smaller, tidier,
+more idiomatic patch that leaves the boundary open is a failure. Minimal
+means *the smallest repository-native change that satisfies everything
+above it* — not the fewest lines.
+
+## Before You Edit
+
+Establish these from the code, not from assumption:
+
+- The source → sink path or the specific broken control.
+- The attacker-controlled input and the preconditions it needs.
+- **The security invariant** — state it in one sentence. "Only the owning
+  tenant may read this record." "The extracted path must stay inside the
+  destination directory." If you cannot state the invariant, you cannot
+  tell whether your patch enforces it.
+- The narrowest place that invariant can be enforced.
+- The legitimate behavior, public APIs, and error semantics that must
+  survive the change.
+- The repository's existing helpers and precedents for this kind of
+  control. Reach for the codebase's own validator before inventing one.
+
+## The Verification Gates
+
+Run these **in order**. A failure at any gate disqualifies the fix —
+revise the patch or withhold it. Do not compensate for a failed gate by
+making the diff smaller or the write-up longer.
+
+**1. Applicability.** Read the final diff. Confirm it contains nothing
+unrelated, that `fix_before` still matches the file character-for-
+character, and that `start_line`/`end_line` still cover exactly those
+lines. Run the narrowest syntax / import / type check available.
+
+**2. Security closure.** Re-run the original PoC against the patched
+code. If you cannot execute it, re-trace source → control → sink through
+the *patched* source and state precisely which step now fails and why.
+"The fix adds validation" is not closure; "the fix rejects `../` before
+the path reaches `open()`, and `open()` is the only sink on this path" is.
+
+**3. Bypass review.** Re-read the finding and the diff *without* leaning
+on the reasoning that produced the patch — you are looking for what that
+reasoning missed. Trace the changed branches from their direct callers.
+Check equivalent sinks and sibling call sites of the same helper. Try at
+least one alternate malicious input class: different encoding, different
+content type, a null byte, a unicode homoglyph, a nested/doubled
+payload, a different HTTP verb. A control that catches your one payload
+and nothing else has not closed the boundary.
+
+**4. Preserved behavior.** Exercise the legitimate case through the same
+boundary. Confirm the APIs, error semantics, and compatibility
+constraints you recorded still hold. A fix that breaks the feature will
+be reverted, which means the vulnerability comes back.
+
+**5. Repository checks.** Run the focused tests covering the changed
+lines, then the owning package's tests, then the applicable formatter,
+linter, and type checker. Use the repository's own commands.
+
+Where practical, confirm the check would **fail if the security change
+were removed**. A test that passes both with and without the patch is
+proving nothing.
+
+## What Disqualifies a Fix
+
+- It closes your specific payload but not the input class.
+- It sanitizes at the wrong layer — after the value was already used, or
+  in a helper that other callers bypass.
+- It relies on a caller passing the right flag, or on a config the
+  operator has to set.
+- It fails open: the new check sits inside a `try`/`except` that swallows
+  the failure, or returns "allowed" on error.
+- It weakens authentication, authorization, tenant isolation, input
+  validation, sandboxing, or logging to make something else pass. Never
+  do this.
+- It silently accepts, truncates, or reinterprets unsafe state instead of
+  rejecting it.
+- It drags in unrelated refactors, sibling findings, or architectural
+  redesign.
+
+## Withholding the Fix
+
+If you cannot pass the gates, that is a legitimate outcome — say so
+rather than shipping a guess. Drop `fix_after` from the location, leave
+it informational, and put the remediation in prose in
+`remediation_steps` instead. State in `fix_verification` exactly which
+gate you could not clear and what was missing: the command that failed,
+the service you could not start, the decision that needs a human.
+
+Withhold and explain when:
+
+- The complete fix depends on an unresolved product or public-API
+  compatibility decision.
+- The invariant cannot be enforced without cross-subsystem changes you
+  cannot validate.
+- You could not establish that the vulnerable path is real in the
+  current checkout. Do not patch an adjacent weakness as a consolation
+  prize, and do not add speculative defense-in-depth to a path you never
+  proved was reachable.
+
+## Recording It
+
+Everything above goes in `fix_verification`, which is required whenever
+any location carries a `fix_after`. Write the actual commands and their
+results, grouped by gate, and mark every gate you could only reason
+about — rather than execute — as an explicit gap. Do not hide proof
+gaps; a reviewer who knows gate 5 was skipped can run it themselves, but
+one who was told it passed cannot.

+description: Qualitative rubric for what actually deserves high/critical severity, and an acceptance checklist to apply before rating a finding
+---
+
+# Severity Calibration
+
+CVSS gives you a number once you have chosen the metrics. This skill is
+about choosing them honestly — deciding what class of issue genuinely
+belongs at each severity before you fill in the vector.
+
+Calibrate severity **after** you have established reachability and run
+the counterevidence pass, never before. Severity is a conclusion, not an
+opening position.
+
+## The Test That Matters
+
+Before rating anything high or critical, ask:
+
+> Would this be accepted as high/critical in serious audit or bug bounty
+> triage, by a firm putting its reputation on the line?
+
+If the honest answer is "only if you accept a chain of assumptions", it
+is not high. Rate the weakness you proved, not the worst case you can
+imagine reaching from it.
+
+## Critical
+
+Reserve for findings where a realistic attacker gets decisive control or
+mass data access, with evidence:
+
+- Unauthenticated remote code execution, or command/code execution
+  reachable by any user on internet-exposed surface.
+- Full authentication bypass, or trivially forgeable authentication
+  (accepted unsigned tokens, `alg: none`, signature not verified).
+- Mass extraction of other users' or other tenants' sensitive data.
+- Compromise of signing keys, control-plane credentials, or credentials
+  granting broad infrastructure access.
+- Complete cross-tenant isolation failure in a multi-tenant system.
+
+Factors that push a high up to critical: no authentication required,
+internet reachable, zero user interaction, wormable/self-propagating,
+or the impact spans all tenants rather than one.
+
+## High
+
+- Authenticated RCE, or RCE requiring a common non-privileged role.
+- Privilege escalation crossing a real trust boundary (user → admin,
+  tenant → tenant, read → write on protected objects).
+- Object-level authorization failures exposing or modifying other users'
+  sensitive data at scale.
+- SQL injection or equivalent injection reaching real data.
+- SSRF that demonstrably reaches internal services, cloud metadata, or
+  credentials.
+- Sensitive credential or PII exposure that an attacker can actually
+  reach.
+
+## Medium
+
+- Stored XSS in a limited context, or reflected XSS requiring user
+  interaction.
+- CSRF on a meaningful state-changing action.
+- Authorization gaps on lower-value objects.
+- Information disclosure that materially aids a further attack.
+- Findings whose high-impact version is blocked by a real constraint you
+  confirmed (internal-only exposure, a required privileged role, a
+  narrow precondition).
+
+## Low / Informational
+
+- Missing security headers, cookie flag issues, verbose errors.
+- Self-XSS, or XSS requiring the victim to paste a payload.
+- Open redirect with no credential or token leakage.
+- Rate-limiting and enumeration issues without a demonstrated impact.
+- Defense-in-depth gaps with no reachable exploitation path.
+
+## Usually NOT High or Critical
+
+These are over-rated constantly. Each needs unusual, demonstrated
+circumstances to exceed medium:
+
+- Self-XSS and clickjacking on non-sensitive actions.
+- Missing headers, cookie attributes, TLS configuration nits.
+- Open redirect on its own.
+- Theoretical memory-safety issues with no reachable attacker input.
+- "Could matter if chained with several unproven assumptions."
+- Anything already requiring admin, shell, or physical access — if the
+  attacker already has that, the finding adds little.
+- Session-management weaknesses that require the attacker to already
+  hold a victim secret (a stolen cookie, an intercepted link). The
+  acquisition of that secret is not free; unless the *same* finding shows
+  how to obtain it, this is usually low/medium.
+- Enumeration that only confirms an account, domain, or version exists.
+
+## Downgrade, Don't Delete
+
+A finding that turns out to be constrained gets a lower severity — not a
+silent drop. Internal-only reachability, a required privileged role, or a
+narrow precondition are all reasons to reduce severity and say so in the
+report. They are not reasons to withhold the finding.
+
+Equally: missing evidence about deployment or exposure lowers your
+**confidence**, not the severity floor. Do not treat "I could not confirm
+this is internet-facing" as if it were "this is internal-only".
+
+## Acceptance Checklist for High / Critical
+
+All of these must be true. If any is not, drop a level:
+
+- [ ] The attack path is realistic and in scope — not a lab-only
+      condition, not dependent on an unproven prior compromise.
+- [ ] The attacker position required is one an attacker can actually
+      obtain, and the CVSS `privileges_required` / `attack_complexity`
+      reflect that honestly.
+- [ ] The impact is material and demonstrated, not asserted — `C:H` /
+      `I:H` mean proven broad or systemic read/write, not one record.
+- [ ] The counterevidence pass found no constraint that meaningfully
+      limits exploitation, or you have explained why the constraint does
+      not hold.
+- [ ] You have concrete evidence of reachability, not an assumption
+      about how the application is deployed.
+- [ ] You would defend this rating in a client debrief.
+
+## Output
+
+Severity still comes from the CVSS vector — this rubric decides which
+vector is honest. When your intuitive rating and the computed CVSS
+severity disagree, re-examine the metrics: usually one of
+`privileges_required`, `attack_complexity`, or the impact triad was set
+optimistically. Fix the metric, do not override the result.

+description: Enumeration discipline for reading code — which locations to keep as separate candidates, which safe siblings prove nothing, and the per-family sweeps that are routinely missed
+---
+
+# Source-Aware Discovery
+
+Reading code for bugs fails in two directions. You collapse many real
+instances into one candidate and under-report, or you stop at the loudest
+issue in a file and never sweep the family around it.
+
+This skill is about *what to enumerate*, not how to exploit it — the
+vulnerability-class skills cover exploitation. Discovery decides
+plausibility and preserves evidence; severity comes later.
+
+## Instance Discipline
+
+**One root cause is not one candidate.** If a dangerous helper has six
+call sites and four are independently reachable, that is four candidates
+— not one "the helper is unsafe" note. Each needs its own source, its own
+closest control, and its own line. A reader has to be able to fix them
+individually.
+
+**Do not collapse distinct proof tuples that share a route.** Command
+execution, SSRF, path/file write, parser abuse, template execution, and
+authorization bypass on the same endpoint are separate findings when the
+sink, the broken control, or the impact differ. Sharing a URL is not
+sharing a bug.
+
+**Keep the wrapper and the shared helper both visible.** When the path
+crosses from an entrypoint into a shared sink or control, record both:
+the wrapper proves reachability, the helper is where the fix goes. Losing
+either one makes the finding unactionable.
+
+**A safe sibling is a negative control for itself and nothing else.** A
+correctly-parameterized query three lines above a concatenated one proves
+the developer knew better, not that the concatenated one is safe.
+
+**Label your locations.** Mark each as entrypoint, root control, sink, or
+concrete implementation. Multi-location findings that don't say which
+line is which force the reader to re-derive your analysis.
+
+## Where the Real Control Lives
+
+The most common discovery error is anchoring on the dramatic sink and
+missing the reusable broken control behind it.
+
+- When a resolver, allowlist, denylist, class filter, or guard is the
+  thing that's wrong, that line is the candidate. The transport that
+  reaches it proves reachability — it doesn't replace it.
+- When the same filter or resolver is **duplicated** across core, server,
+  client, plugin, or import packages, each copy is its own candidate.
+  Fixing one leaves the others live.
+- In a concrete strategy / handler / converter / operation subclass, read
+  the specialized helper, not just the top-level `handle` / `apply` /
+  `perform` override. If the subclass splits, filters, canonicalizes, or
+  rebuilds attacker input before delegating to a shared evaluator, the
+  subclass line is the root control.
+- Branch-specific transforms — append, wildcard, fallback, copy/move
+  `from`, default-value, type-resolution — routinely bypass or narrow the
+  shared validator. Keep the branch predicate as its own location. A
+  finding on the shared helper does not close them.
+
+## Family Sweeps
+
+When you find one instance of these, sweep the whole family before
+closing it out.
+
+**Deserialization / object construction.** Enumerate every registered
+codec, deserializer, converter, and container handler — array,
+collection, map, bean, enum, throwable, generic object. A top-level
+parser-config finding does not close a concrete codec that recursively
+re-invokes parsing or type resolution on attacker data.
+
+**XML / parsers.** Enumerate parser factories, readers, converters,
+validators, transformers, and unmarshal entrypoints independently.
+Hardening that is best-effort does not suppress anything: a
+secure-processing flag alone, a `setFeature` call whose failure is
+swallowed or logged, or a safe default factory all leave
+caller-supplied factories and converter paths open.
+
+**Object models for untrusted formats.** Sweep the primitive and
+container helpers that traverse or convert attacker-controlled documents
+— `to*Array`, `get*`, numeric conversion, `parse*`, iterators, size
+accessors, unchecked casts, allocation loops. Missing type, size, shape,
+recursion, or numeric guards here cause type confusion, unbounded
+traversal, and resource exhaustion. These sweeps create candidate rows,
+not automatic findings — promote one only when malformed input plausibly
+reaches it and the missing guard has a concrete security effect.
+
+**Archive extraction and import/restore.** Keep four things visible per
+operation: the member name, the destination join, the containment check,
+and the extract/write call. A later copy step, manifest gate, or UUID
+check does not close it if the write already happened. "The stdlib
+normalizes paths" is not containment evidence — the code must show
+per-entry containment *before* the write, including symlink, hardlink,
+and recursive-copy paths. The write does not need to escape the app root
+to matter: overwriting config, a peer tenant's directory, or a shared
+imported subtree is still file impact.
+
+**Path-sensitive filesystem operations.** Enumerate each exported
+operation separately — restore, import, export, backup, copy, move,
+download, open, key/config fetch. For each, keep the decode, join,
+normalize, canonicalize, strip-prefix, extension-check, and
+destination-selection lines candidate-visible.
+
+**Static-file and resource serving.** The candidate is the line that
+decides whether an attacker-chosen path is allowed: the allowlist, the
+matcher, the canonicalization, the URL decode, the resource selection. Do
+not substitute a safer sibling handler for the vulnerable legacy one.
+
+**Outbound requests.** For URL importers, webhook and callback clients,
+preview/render fetchers, `downloadFrom`-style helpers, and
+redirect-following clients: enumerate each attacker-controlled
+destination and its closest allow/deny/redirect control. Do not drop the
+row because the fetch is an intended feature, because the filter is
+operator-configured or empty by default, or because it only runs
+pre-request.
+
+**Command and action runners.** Enumerate every attacker-controllable
+argument type and execution mode before you call command injection
+covered. Type-safety maps, unsafe-type denylists, template substitution,
+shell wrapping, direct-exec branches, and API-side argument ingestion are
+each separate controls. A denylist covering three types says nothing
+about the no-op typecheck branches that still render into a shell string.
+Frontend widget constraints are not controls at all.
+
+**Query APIs (SQL, NoSQL, LDAP, XPath, and friends).** Do not suppress
+because the endpoint is already user-facing, because it's an insert
+rather than a read, or because a later business check appears to limit
+the effect. If attacker input reaches query syntax or selector operators,
+carry it forward and record the later check as counterevidence.
+
+**Structured patch / edit APIs.** For JSON Patch, document edits, and
+config mutations, enumerate the request-selected operations — add,
+remove, replace, move, copy, test. Operation-specific path transforms,
+array-append handling, and wildcard selection stay candidate-visible when
+they feed a shared evaluator or binder.
+
+**Authentication state machines.** The candidate is the line that
+installs or reuses a principal, credential, token, issuer, or protocol
+state *after* a transition — pre-auth to authenticated, TLS upgrade,
+redirect, assertion consumption, IdP handoff. Missing rebind or
+reauthentication at that seam authenticates the wrong identity.
+
+**SSO / SAML / federation.** Keep response and assertion validators
+distinct from generic claims authorizers and from service-method
+authorization; they fail differently. Include the lines doing assertion
+selection, list indexing, DOM access, node cloning, signed-object lookup,
+subject confirmation, recipient, audience, destination, ACS URL, and
+issuer binding — each decides *which* assertion is trusted.
+
+The signature failure to watch for: a validation loop or a
+`foundValid`-style flag, followed by a **separate** fixed-index,
+first-element, clone, re-serialization, or return path. Treat that later
+selection line as the broken control until you have proven the validated
+object and the consumed object are byte-identical and equally bound. This
+is the validated-vs-consumed mismatch, and it is invisible if you only
+read the validator.
+
+**Realms and authenticators.** Enumerate the concrete implementations —
+LDAP, Kerberos, PAM, SAML, OAuth/OIDC, custom realms — before promoting a
+generic HTTP auth finding. In multi-step or TLS-upgraded binds, keep the
+bind/rebind and credential-installation line visible.
+
+**Self-service update routes.** Include the guard that compares the
+requested object against the persisted one. Missing checks on
+security-sensitive scalars and collection aliases let a user change their
+own identity, roles, group membership, tenancy, or account-recovery
+properties.
+
+**Protocol utility code.** In protocol-heavy repositories, read the
+version, capability, feature, and negotiation helpers even when the
+obvious candidates are REST and admin routes. Look for `Version`,
+`versionCompare`, `Capability`, `Feature`, `Negotiation`, and the
+comparator methods around them — downgrade and confusion bugs live there,
+and nobody looks.
+
+**Public webhook / status / callback endpoints.** Enumerate these
+independently from nearby credential bugs whenever they read protected
+objects, trigger jobs, or mutate protected state.
+
+## Cross-Boundary Inputs
+
+In frameworks and libraries, stored client, tenant, application, IdP,
+exception, and imported-configuration values are attacker-controlled when
+they are later rendered, evaluated, parsed, or used for authorization —
+provided there is a plausible runtime path from some boundary. Do not
+suppress just because the writer lives outside this repository. That
+requires evidence the value is trusted-only in normal deployments, not an
+assumption.
+
+Similarly, do not suppress a high-impact candidate because the API is
+deprecated, opt-in, or documented as dangerous. Record that as a
+precondition and keep the candidate — shipped code with a bypassable
+control is shipped code.
+
+## The Finding Bar
+
+Worth opening a candidate: authorization bypass, confused deputy, SSRF,
+path traversal, injection with a real sink, cross-tenant exposure,
+sensitive state change without enforcement, sandbox or trust-boundary
+escape.
+
+Not worth it: "this could use more validation" with no path, style and
+maintainability complaints, and cosmetic variants of a candidate you
+already opened.
+
+Keep reading until no distinct plausible candidate remains — then record
+what you swept with `record_coverage`, including the families that came
+back clean.

+description: Microsoft Azure and Entra security testing covering RBAC, Privileged Identity Management, Conditional Access, service principals, managed identities, Storage SAS, Key Vault, workload escalation, and cross-plane privilege paths
+---
+
+# Azure and Microsoft Entra Security
+
+Azure security spans two related but distinct control planes:
+
+- **Microsoft Entra ID** (formerly Azure AD): tenant identity, users, groups, applications, service principals, directory roles, authentication, and Conditional Access.
+- **Azure Resource Manager (ARM):** management groups, subscriptions, resource groups, resources, Azure RBAC, managed identities, and service-specific control/data planes.
+
+Do not equate an Entra directory role with an Azure resource role. A principal can be weak in one plane and privileged in the other, and many escalation paths cross between them.
+
+## Scope and Identity Baseline
+
+Record before testing:
+
+- tenant ID, cloud environment, management groups, subscriptions, and directories in scope
+- current user/service principal/managed identity object ID and home tenant
+- direct and group-derived Entra directory roles
+- Azure role assignments, scope, inheritance, conditions, and deny assignments
+- authentication method, token audience, Conditional Access result, and PIM activation state
+- test versus production subscriptions and any cross-tenant/B2B context
+
+Start with native CLI context:
+
+```bash
+az cloud show --output json
+az account show --output json
+az account list --all --refresh --output json
+az account management-group list --no-register --output json
+az ad signed-in-user show --output json
+az role assignment list --subscription <subscription-id> --all --include-inherited --output json
+az role assignment list --subscription <subscription-id> --assignee <user-object-id> --all --include-inherited --include-groups --output json
+az role definition list --subscription <subscription-id> --output json
+```
+
+For a service principal, `az ad signed-in-user show` does not apply; resolve the current client/service-principal object explicitly from the reviewed credential context. `--all` remains scoped to the selected subscription, and `--include-groups` depends on Microsoft Graph and can still miss nested or workload-derived paths. Repeat the inventory per tenant, management-group root, and in-scope subscription. Never infer identity only from a display name.
+
+## Azure RBAC
+
+An Azure role assignment joins three elements: a security principal, a role definition, and a scope. Scope inheritance runs from management group to subscription to resource group to resource.
+
+### Review
+
+- Enumerate direct, group-derived, inherited, eligible, and active assignments separately.
+- Expand custom role `Actions`, `NotActions`, `DataActions`, and `NotDataActions`; the role name is not a reliable summary.
+- Inspect assignment conditions/ABAC, deny assignments, management-group inheritance, and cross-tenant principals.
+- Identify broad scopes for Owner, Contributor, User Access Administrator, Role Based Access Control Administrator, and custom equivalents.
+- Check who can write role assignments, role definitions, policies, locks, deployments, managed identities, credentials, or compute configuration.
+- Distinguish ARM control-plane permission from service data-plane permission. Contributor over a resource may still gain its data through code/configuration or a managed identity even without direct data actions.
+
+### High-Value Cross-Plane Paths
+
+- Active Microsoft Entra Global Administrator can elevate into Azure by using `Microsoft.Authorization/elevateAccess/action` to grant User Access Administrator at the root `/` scope. That root assignment can persist after PIM deactivation until it is explicitly removed.
+- `Microsoft.Authorization/roleAssignments/write` or equivalent role-management authority → grant a stronger role at an allowed scope.
+- Ability to modify a VM, VM extension, Function App, App Service, Container App, Automation runbook, deployment script, Logic App, or similar workload → execute in that workload's identity and network context.
+- Ability to attach or replace a user-assigned managed identity, together with the host resource write path and `Microsoft.ManagedIdentity/userAssignedIdentities/assign/action` → inherit its downstream Azure permissions.
+- Ability to modify federated identity credentials, app credentials, certificates, or owners → impersonate a service principal/application.
+- Ability to read deployment outputs, app settings, runbook variables, storage, snapshots, disks, backups, or diagnostic settings → recover credentials or sensitive data.
+- Broad policy/deployment rights at a parent scope → affect many child resources even when individual resource assignments appear narrow.
+
+Model each path using exact principal, action, resource, scope, condition, and resulting effective permission. Check Azure Policy and deny assignments before declaring a theoretical path exploitable.
+
+## Privileged Identity Management (PIM)
+
+[Microsoft Entra Privileged Identity Management](https://learn.microsoft.com/en-us/entra/id-governance/privileged-identity-management/pim-configure) provides time-based and approval-based activation for privileged access. It can govern Microsoft Entra roles, Azure resource roles, and PIM for Groups.
+
+PIM terminology:
+
+- **eligible:** the principal must activate before using the role
+- **active:** the principal can use the role without activation
+- **permanent/time-bound:** duration of eligibility or assignment
+- **activated:** a currently active, time-limited instance created from eligibility
+
+### What to Test
+
+- Permanent active assignments where eligible/JIT access is expected.
+- Permanent eligibility without access reviews, expiration, or a business need.
+- Roles that activate without MFA, approval, justification, notification, or a short duration.
+- Approvers who can approve themselves indirectly, lack separation of duties, or no longer own the system.
+- Group-based eligibility where group ownership/membership can be changed by a lower-privileged principal.
+- PIM for Groups on role-bearing groups where a lower-privileged principal can alter ownership, membership, or activation controls.
+- PIM settings applied to one privileged role but omitted from a custom/equivalent role.
+- Directory-role PIM configured while equivalent Azure resource roles remain permanently active, or vice versa.
+- Standing service-principal/workload access. Eligible Azure RBAC via PIM is a user-centric control; service principals and managed identities remain standing or time-bounded active assignments, not user-style eligible activations.
+- Activation sessions that remain useful through cached tokens, active sessions, delegated jobs, or downstream credentials after the intended window.
+- Audit/alert coverage for assignment, activation, approval, renewal, extension, and role-setting changes.
+
+With sufficient Microsoft Graph read permissions, compare current schedule instances:
+
+```bash
+az rest --method GET \
+  --url 'https://graph.microsoft.com/v1.0/roleManagement/directory/roleEligibilityScheduleInstances?$expand=principal,roleDefinition'
+
+az rest --method GET \
+  --url 'https://graph.microsoft.com/v1.0/roleManagement/directory/roleAssignmentScheduleInstances?$expand=principal,roleDefinition'
+```
+
+Those endpoints cover Microsoft Entra role schedules. Follow `@odata.nextLink`, and record the exact Graph permissions or delegated role used because weak tokens silently under-enumerate. Azure resource-role PIM is exposed through ARM's `Microsoft.Authorization` role eligibility/assignment schedule resources; keep the two inventories separate:
+
+```bash
+az rest --method GET \
+  --url "https://management.azure.com/subscriptions/<subscription-id>/providers/Microsoft.Authorization/roleEligibilityScheduleInstances?api-version=2020-10-01&\$filter=atScope()"
+
+az rest --method GET \
+  --url "https://management.azure.com/subscriptions/<subscription-id>/providers/Microsoft.Authorization/roleAssignmentScheduleInstances?api-version=2020-10-01&\$filter=atScope()"
+```
+
+Follow `nextLink` there as well. For Entra directory-role inventory, reviewed readers commonly need `RoleEligibilitySchedule.Read.Directory` and `RoleAssignmentSchedule.Read.Directory` or an equivalent delegated role/application permission set.
+
+## Conditional Access and Authentication
+
+[Conditional Access](https://learn.microsoft.com/en-us/entra/identity/conditional-access/overview) is Entra's identity-driven policy engine and is evaluated after first-factor authentication.
+
+Review:
+
+- policies in on/off/report-only state and coverage of users, groups, roles, applications, authentication contexts, and workload identities
+- exclusions for break-glass accounts, admins, service accounts, guest users, locations, devices, or applications
+- admin and management surfaces not covered by phishing-resistant MFA or appropriate authentication strength
+- legacy authentication and non-interactive flows that do not receive the intended policy
+- device compliance/join trust, named locations, sign-in/user risk, session lifetime, continuous access evaluation, and token protection where used
+- policy gaps caused by nested groups, guest/home tenant behavior, service principals, managed identities, or application-specific grant paths
+- whether emergency access exclusions are narrowly scoped, monitored, credential-protected, and exercised
+
+For workload identities, Conditional Access applies only in limited cases: directly targeted tenant-owned single-tenant service principals can be controlled, but managed identities, Microsoft-owned service principals, most third-party SaaS service principals, and multitenant app registrations do not inherit human MFA semantics. Target the enterprise application service-principal object, not just the app registration, and verify the control at token issuance.
+
+Use sign-in logs and the Conditional Access result to distinguish policy non-application from policy failure. Report-only evaluation is evidence of intended future control, not enforcement.
+
+## Applications, Service Principals, and Workload Identity
+
+An app registration is the tenant-level application definition; a service principal is the local security principal representing an application instance in a tenant.
+
+Inventory:
+
+- owners of application and service-principal objects, separately
+- delegated versus application permissions and admin consent
+- client secrets/certificates, expiry, unused/stale credentials, and credential-add rights
+- federated identity credentials: issuer, subject, audience, repository/branch/environment claims
+- multitenant applications, publisher verification, consent grants, and cross-tenant access settings
+- service-principal role assignments in both Entra and Azure
+- automation/CI connections and whether test identities can reach production
+
+Keep application-object authority separate from service-principal authority. Application ownership and `Application.ReadWrite.*` can add owners, client secrets, certificates, or federated credentials on the app object; service-principal ownership and `ServicePrincipal.ReadWrite.*` govern the enterprise application instance. Admin consent is a separate control plane from credential management. Also trace group ownership/membership where a role-bearing group grants app, vault, Azure RBAC, or Entra role access. A secret's metadata proves age/expiry but not that its value is retrievable.
+
+### Managed Identities
+
+Managed identities remove stored credentials but still carry authority:
+
+- **system-assigned:** lifecycle is tied to one Azure resource
+- **user-assigned:** independent resource assignable to multiple workloads
+
+Enumerate identity attachments and downstream role assignments. Check who can attach/detach the identity, execute or deploy code in the host workload, access its metadata/token endpoint, or reuse a user-assigned identity across environments. Treat workload control as potential identity control.
+
+## Storage and SAS
+
+A Shared Access Signature (SAS) delegates access to Azure Storage through a signed URI. Review:
+
+- SAS type: user delegation, service, or account SAS
+- services/resource types, permissions, start/expiry, protocol, IP restriction, and stored access policy
+- long-lived tokens in source, CI logs, tickets, browser history, application settings, or public URLs
+- account-key use, `listKeys` authority, and key-rotation feasibility
+- public container/blob access, anonymous listing, network rules, private endpoints, and trusted-service exceptions
+- storage RBAC and whether principals can generate user-delegation keys or list account keys
+
+Microsoft recommends a user delegation SAS where supported because it is secured with Entra credentials rather than the account key. User delegation keys and SAS values are time-limited and user-scoped; service/account SAS values derive from account keys, and only service SAS can bind to stored access policies. User delegation SAS is limited to Blob/Data Lake and has a maximum seven-day validity per delegation key. A SAS is a bearer credential; possession can be sufficient even when the holder has no visible Azure role assignment.
+
+Validate each token against its signed permission/resource/time restrictions. Do not treat a redacted or expired SAS found in code as current unauthorized access.
+
+## Key Vault, Secrets, and Certificates
+
+- Determine whether the vault uses Azure RBAC or legacy access policies. The active model is controlled by `enableRbacAuthorization`; RBAC mode invalidates access-policy evaluation for data-plane access.
+- Enumerate who can read secrets, keys, and certificates; who can change access; and who controls workloads with vault-reading identities.
+- Review public network access, firewall/private endpoints, soft delete, purge protection, logging, secret expiry, and rotation.
+- Distinguish key operations (sign/decrypt/wrap) from key export and secret-value read.
+- Look for vault references copied into app settings without corresponding identity isolation.
+- Test backup/restore and cross-subscription permissions where in scope.
+
+Legacy access-policy write authority on the vault resource can still become self-granting in access-policy mode. In RBAC mode, the equivalent finding depends on `DataActions` or role-assignment control, not on legacy access-policy mutation.
+
+## Credential-Equivalent Actions
+
+Treat the following as credential-equivalent or near-equivalent authority when the downstream scope matches:
+
+| Surface | Action or state | Why it matters |
+|---|---|---|
+| Azure RBAC | `Microsoft.Authorization/roleAssignments/write` | grants new authority directly |
+| Root scope | `Microsoft.Authorization/elevateAccess/action` | bridges Entra Global Administrator into Azure root access |
+| Managed identity | host config write plus `.../userAssignedIdentities/assign/action` | attaches a stronger identity to attacker-controlled code |
+| App object | add secret/cert/federated credential or owner | permits application impersonation |
+| Service principal | add credential/owner or modify federation | permits enterprise-app impersonation |
+| Storage | `listKeys` or account-key disclosure | enables service/account SAS and broad account access |
+| Storage | `generateUserDelegationKey` with matching data rights | enables user delegation SAS issuance |
+| Key Vault | secret-value read, key sign/decrypt/wrap, or self-grant path | grants equivalent access even without export |
+
+## Compute, Network, and Data Services
+
+- VM extensions, Run Command, serial console, disks/snapshots, images, custom script, and boot diagnostics
+- App Service/Functions deployment slots, publishing credentials, SCM/Kudu, app settings, storage mounts, and managed identities
+- AKS control plane/RBAC, workload identity federation, kubeconfig retrieval, node/resource-group rights, and private API reachability
+- Container Apps/ACI environment variables, registries, identities, revisions, and exec surfaces
+- Automation accounts/runbooks, Logic Apps/connectors, Data Factory linked services, deployment scripts, and DevOps/service connections
+- NSGs, route tables, public IPs, load balancers, private endpoints, DNS, peering, Bastion, firewalls, and JIT VM access
+- SQL, Cosmos DB, Storage, Service Bus, Event Hubs, and other service-specific data-plane authorization
+
+Map whether a principal that lacks direct data access can reconfigure networking, identity, code, diagnostics, export, backup, or deployment to gain an equivalent capability.
+
+## Testing Methodology
+
+1. **Establish context** — tenant, subscription, cloud, principal, token audience, and active PIM state.
+2. **Inventory both role planes** — Entra directory roles and Azure resource roles with groups, scope, inheritance, conditions, eligible/active state, and custom definitions.
+3. **Map identity objects** — applications, service principals, managed identities, owners, credentials, federation, and consent.
+4. **Review policy gates** — Conditional Access, authentication methods, PIM settings, Azure Policy, deny assignments, and network restrictions.
+5. **Enumerate workloads/data** — identify where control-plane modification yields code execution, identity use, secrets, backups, or data-plane access.
+6. **Build effective-access paths** — principal → permission → resource change/identity → downstream privilege or data.
+7. **Cross-check logs** — Entra sign-in/audit, PIM, Azure Activity, resource logs, and Defender/Sentinel alerts where available.
+8. **Re-evaluate boundaries** — guest/home tenant, management-group inheritance, test/production, group ownership, and workload identities.
+
+## Validation
+
+For each finding, include:
+
+1. tenant/subscription and exact principal/object IDs
+2. assignment source, role definition, scope, inheritance, condition, and PIM state
+3. relevant Conditional Access/authentication result
+4. exact Azure/Graph action and target resource
+5. effective permission or cross-plane path demonstrated
+6. policy, deny, network, licensing, or configuration prerequisites
+7. audit/sign-in/activity evidence and remediation at the correct control plane
+
+## Common False Positives
+
+- Role name appears privileged but custom `Actions`/`DataActions`, conditions, scope, or deny assignments block the claimed action.
+- Contributor is reported as able to assign roles without `roleAssignments/write` or an alternate workload/identity path.
+- An eligible PIM assignment is described as standing active access.
+- A Conditional Access policy exists but is report-only, excluded, or does not apply to the tested principal/application.
+- An app registration is confused with its service principal in another tenant.
+- A managed identity is present but the tester cannot control its host or obtain a token in the relevant context.
+- An expired/revoked SAS or credential metadata is reported as usable access.
+- ARM access is assumed to grant service data-plane access automatically.
+
+## Tooling
+
+### Azure CLI and Microsoft Graph
+
+Use the official Azure CLI for resource context and `az rest` for reviewed ARM/Graph queries not exposed cleanly by a command group. Record CLI/API versions and requested permissions. Broad directory inventory often requires Microsoft Graph application permissions and admin consent; absence of results under a weak token is not proof that objects do not exist.
+
+### Prowler (Conditional)
+
+[Prowler](https://github.com/prowler-cloud/prowler) provides maintained Azure configuration/compliance checks. Install a reviewed pinned release in an isolated environment:
+
+```bash
+python -m pip install 'prowler==<reviewed-version>'
+prowler azure --az-cli-auth --subscription-ids <subscription-id>
+```
+
+Other documented modes include service-principal, browser, and managed-identity authentication. Use a dedicated read-only audit principal with only the documented tenant/subscription permissions. Scope subscription IDs explicitly, protect reports as sensitive asset/identity inventories, account for API volume/throttling, and do not enable cloud upload for assessment data unless approved. Prowler findings are configuration leads; trace effective principal/action/resource paths before treating them as exploitable.
+
+## Summary
+
+Azure security is an identity-and-scope graph across Entra and ARM. Test directory roles, Azure RBAC, PIM, Conditional Access, service principals, managed identities, delegated storage access, workload control, and service data planes as one system while preserving the distinction between each control plane.

 4. **Prioritize by risk** - critical assets and high-value targets first
 
+## Establish the Threat Model
+
+Every scan needs one shared answer to "who is the attacker here, and what are they attacking" — black-box or white-box. Without it, five agents derive five different answers and their findings cannot be reconciled. Call `get_threat_model` on the target (a host, a URL, or a repository path) before you spawn hunters; if nothing is cached, derive one and persist it with `save_threat_model`. It is cached per target, so a later scan of the same host or tree reads it back instead of paying for it twice, and a model written from source is read back by an agent testing the deployment.
+
+**When the target includes a repository**, derive it up front: the code tells you the boundaries, entrypoints, and controls before you send a single request.
+
+**Black-box, the ordering inverts.** You cannot model a target you have not seen, so recon comes first: spawn reconnaissance, and write the model from what it found — the hosts and ports that answered, the technology fingerprints, the authentication and session model, the roles and tenants you can distinguish, the endpoints and parameters enumerated. Then spawn the hunters against that model. Do not stall the scan waiting for a perfect picture and do not skip the step because the picture is partial: mark what is inferred rather than observed and let it be corrected. A black-box model that says "admin panel at `/admin` appears to be IP-restricted — unverified" is worth far more than no model, because it tells the next agent exactly what to go check.

+Either way you write it with the least information anyone on this scan will ever have, so expect it to be wrong somewhere. Subagents correct it with `amend_threat_model`, which appends an attributed addendum instead of overwriting — expect many of these on a black-box run, as authenticating, pivoting between roles, and reaching internal surfaces is exactly what turns inference into fact. Read the amendments back before you write the final report: an agent telling you a boundary you called trusted is attacker-reachable is a finding about your model, not a note. Only call `save_threat_model` again to fold accumulated amendments into the body; it replaces the document and clears them.

+## Reconcile Coverage Before Finishing
+
+Coverage entries are shared and mutable. Before `finish_scan`, list the `needs_follow_up` rows: each one is either work you still owe or a row somebody already resolved without updating. Assign the former to a subagent and have it call `update_coverage` on the existing entry rather than recording a second one — a stale open item sitting next to its own resolution is worse than either alone.

+
+### Attribute transitive CVEs to the direct dependency
+
+With `--list-all-pkgs`, each `.Results[].Packages[]` entry carries `ID`
+(`name@version`), `Relationship` (`direct` / `indirect`) and `DependsOn` (the
+`ID`s it resolves to). For every vulnerable package that is **indirect**, walk
+the `DependsOn` graph backwards to find the `direct` package(s) whose closure
+contains it, then pass to `create_dependency_report`:
+
+- `introduced_by` — the direct dependency as `name@version` (e.g.
+  `express@4.18.1`). If several direct dependencies pull it in, pick the
+  primary one and name the rest in `technical_analysis`.
+- `dependency_path` — the shortest resolution chain from that direct
+  dependency to the vulnerable package, joined with ` > ` (e.g.
+  `express@4.18.1 > body-parser@1.20.0 > qs@6.10.2`).
+- Omit both when the vulnerable package is itself a direct dependency.
+
+If the ecosystem's lockfile gives trivy no graph (`DependsOn` absent), derive
+the chain from the package manager instead (`npm ls <pkg>`, `pnpm why <pkg>`,
+`yarn why <pkg>`, `pipdeptree --reverse -p <pkg>`, `go mod graph`,
+`mvn dependency:tree`, ...) — and if that also fails, leave the fields out
+rather than guessing.
+
+For transitive findings, `remediation_steps` must be actionable at the
+**direct-dependency level**: upgrading the vulnerable package directly is
+usually impossible from the app's own manifest. Say which direct dependency to
+bump (a version whose closure resolves the fixed version), or how to force the
+resolution (npm `overrides` / yarn `resolutions` / pnpm `pnpm.overrides` /
+Maven `dependencyManagement` / Gradle resolution strategy / `go mod edit`),
+not just "upgrade <vulnerable pkg> to <fixed>".
+
+### Usage / reachability analysis (required for every dependency CVE)
+
+For every CVE you are about to report, run a static usage analysis and record
+the result in the structured `reachability` + `reachability_evidence` fields.
+The level is an **evidence ladder, never an exploitability verdict** — claim
+only what you proved, and cite the proof. It never changes severity (that is
+`advisory_cvss` alone); it exists so the reader can prioritize.
+
+**Go — use govulncheck (real call-graph analysis):**
+
+```bash
+# Symbol-level: reports only vulnerabilities whose vulnerable functions are
+# actually reachable from application code. Needs the Go toolchain + module
+# deps; if either is missing, fall back to the checks below rather than
+# claiming a level.
+if command -v govulncheck >/dev/null && go version >/dev/null 2>&1; then
+  govulncheck -format json ./... > "$ART/govulncheck.json" || true
+fi
+```
+
+- A finding with a call stack ⇒ `reachability=reachable_call_path`, put the
+  call-path excerpt (entrypoint → vulnerable function) in
+  `reachability_evidence`.
+- Listed as affecting a required module but with no reachable symbol ⇒ fall
+  back to the import/symbol checks below (`imported` / `not_imported`).
+
+**All other ecosystems — import check, then symbol match:**
+
+1. **Import check.** Search application code (exclude lockfiles, vendored
+   deps, `node_modules`, build output) for imports of the vulnerable package:
+   `ast-grep`/`rg` for `import`/`require`/`from X import` of the package (and
+   its ecosystem import name, which may differ from the registry name, e.g.
+   `PyYAML` → `yaml`). No hits ⇒ `not_imported`, with the search scope stated
+   in `reachability_evidence`. For a **transitive** dependency, the check is
+   whether application code imports it directly; if not, it is reachable only
+   through the direct dependency — check whether the direct dep's usage can
+   hit it (if unclear, use `imported` when the direct dep is used at all).
+2. **Symbol match — per CVE, not per package.** Read each CVE's own advisory
+   (GHSA/NVD/OSV `affected[].ecosystem_specific.imports` or the advisory
+   text) for the affected functions/classes/APIs. Search application code for
+   those symbols (`ast-grep` pattern or `rg -n`). Hits ⇒
+   `vulnerable_symbol_used`, with repo-relative `file:line` of each hit (up
+   to a handful) in `reachability_evidence`. Imported but no affected-symbol
+   usage found (or the advisory names no symbols) ⇒ `imported`.
+   Different CVEs on the same package usually affect **different** symbols
+   (one hits a parser, another a header check) — never copy one CVE's
+   verdict/evidence onto its siblings; run the symbol search against each
+   CVE's own affected-symbol list. The import check (step 1) is the only
+   part shared across a package's CVEs.
+3. **Source-to-sink trace — do this whenever step 2 found a symbol hit.** A
+   symbol hit alone says the code calls the vulnerable API; it does not say
+   who can reach it. Start at the sink (the exact line that calls the
+   vulnerable function) and walk backwards hop by hop to the source: the
+   entry point that carries untrusted input (HTTP route, CLI argument, queue
+   or webhook payload, uploaded file, config value). Read each intermediate
+   function; when a hop is a thin wrapper, go one step deeper — never stop at
+   the first caller. Record what each hop enforces: authentication, a role
+   check, validation, a feature flag, a size or type limit, a default that is
+   off in production.
+   Write the chain into `reachability_evidence` as
+   `entry point -> intermediate call -> package call` with a
+   repository-relative `file:line` for every hop, and say who controls the
+   input. If no source reaches the sink, say that too — the level stays
+   `vulnerable_symbol_used` (the call is real), and the trace is what tells
+   the reader it is only reachable from, say, an operator CLI.
+4. If the analysis was not performed or is inconclusive (obfuscated code,
+   dynamic loading, unparsable sources) ⇒ `unknown` and say why in
+   `assumptions`.
+
+Cheap-first budgeting: the import check is one search per package — always do
+it. Do the per-CVE symbol match for every CVE whose advisory names affected
+symbols (they can be batched into one multi-pattern search per package);
+prioritize `critical`/`high`/KEV when the budget is tight; a CVE whose symbol
+search was skipped may still be reported as `imported` (the import check is
+real evidence), but its `reachability_evidence` must state that the
+affected-symbol check was not performed, so a skipped search is never
+mistaken for a completed one with no hits. Never let this analysis stall
+reporting — `unknown` with a reason beats an unverified claim.
+
+Anti-overclaim rules:
+
+- `not_imported` still does NOT mean safe (dynamic `import()`/reflection/
+  framework wiring evade static search) — never phrase it as "not exploitable".
+- `reachable_call_path` is reserved for call-graph tools (govulncheck); a
+  symbol grep hit is `vulnerable_symbol_used`, no matter how convinced you are.
+- The tool rejects any level other than `unknown` without
+  `reachability_evidence`.
 
 ### Reachability is a confidence modifier, not a gate
 
 Do NOT suppress or downgrade a known CVE just because you could not prove the
 vulnerable code path is reachable. Report it, set `advisory_cvss` from the
-advisory, and use `assumptions` to note reachability (e.g. "the vulnerable
+advisory, record the usage analysis in `reachability`/`reachability_evidence`,
-`template()` API does not appear to be imported in application code, so practical
+and use `assumptions` for anything softer. If you *can* actually trigger the
-exploitability is uncertain"). If you *can* show reachability or chain it into a
+vulnerable path or chain it into a dynamic exploit, additionally report that
-dynamic exploit, do that and report it as a normal dynamic finding with
+as a normal dynamic finding with `create_vulnerability_report` (the standalone
-`create_vulnerability_report` instead.
+CVE stays in its own `create_dependency_report`).

+  a triage step.
+
+### Contextual CVSS
+
+The published score rates the CVE in the abstract. `contextual_cvss_breakdown`
+rates it **here**, in this codebase, and every dependency report must carry
+one. It is the same 8-metric CVSS v3.1 object as a
+normal finding's `cvss_breakdown` (`attack_vector`, `attack_complexity`,
+`privileges_required`, `user_interaction`, `scope`, `confidentiality`,
+`integrity`, `availability`). You never pass a score: the contextual score and
+vector are computed from the breakdown, and when you provide one it determines
+the finding's severity. `advisory_cvss` stays the published reference.
+
+Start from the advisory's own published metrics and change only what your
+evidence proves is different in this codebase:
+
+- `attack_vector` `N`/`A`/`L`/`P` — as deployed. A library reached only by a
+  local CLI is `L`, not `N`.
+- `attack_complexity` `L`/`H` — raise to `H` when the vulnerable path needs a
+  precondition the code enforces (input validation, a non-default flag, an
+  internal-only route).
+- `privileges_required` `N`/`L`/`H`, `user_interaction` `N`/`R` — what this
+  deployment requires before the path is reachable.
+- `scope` `U`/`C` — whether exploitation here escapes the component boundary.
+- `confidentiality`/`integrity`/`availability` `N`/`L`/`H` — the impact in this
+  codebase. `not_imported` code the build still ships is usually `N` across all
+  three.
+
+Ground every metric in the **source-to-sink trace** from the usage analysis
+(step 3 above), not in a general impression of the package. Derive the metrics
+from that chain: `attack_vector`, `privileges_required`, and `user_interaction`
+come from what the source requires; `attack_complexity` comes from the
+preconditions the hops enforce; `confidentiality`, `integrity`, and
+`availability` come from the data and privileges available at the sink.
+
+When you have no source-to-sink trace, still rate the finding: copy the
+published metrics, change only the metrics the usage level itself proves, and
+say so in the reasoning. For example, for a `not_imported` package that the
+build still ships, keep the published metrics and lower `confidentiality`,
+`integrity`, and `availability` to `N`, because no code path reaches the
+vulnerable symbol. Never invent a hop you did not read.
+
+`contextual_cvss_reasoning` is required with the breakdown. Write two to four
+sentences that another engineer can check without opening the repository. Name
+the chain hop by hop as `entry point -> intermediate call -> package call`, with
+a repository-relative `file:line` for each hop, say who controls the input, and
+say what the contextual rating changes. Example: lowering `attack_vector` to
+`L` and `confidentiality` to `L` with "The only caller of `yaml.load` is
+`parse_manifest` in `scripts/import.py:88`, which `cli/commands.py:212` invokes
+for an operator-supplied path behind the `--allow-unsafe-import` flag that
+`deploy/prod.yaml` never sets. No HTTP route reaches that function, so an
+attacker must already hold shell access on the job host, and the parsed data is
+build metadata rather than customer records."
+
+When the published rating already fits this codebase, repeat the published
+metrics in the breakdown and say in the reasoning that the deployment matches
+the advisory. A contextual rating is a claim you must be able to defend, and it
+never replaces `advisory_cvss` as the published reference.
