Merge origin/main into feature/contextual-safety-review

Integration fixes the merge required:
- guard tools after the strict-schema downgrade, so the copy
  dataclasses.replace returns is the object the safety wrapper mutates
- await _ctx_client, which main made async for the Caido bootstrap handle
- pass main's extra_files through with the isolated local sources
- keep DEFAULT_SAFETY_MODE alongside main's new report/state imports
- rebuild the committed viewer bundle from the merged frontend sources
- pin the browser-session safety phrase in test_safety_prompt so it no
  longer matches unrelated prompt text, and stamp safety_mode on the
  workspace-file resume record

+title: "Action Safety"
+description: "Review potentially dangerous actions before they execute"
+---
+
+Action safety is enabled by default and is independent of scan depth. `quick`,
+`standard`, and `deep` control coverage; guarded review controls which effects
+may be executed.
+
+```bash
+strix --target https://example.test
+```
+
+Guarded review permits non-destructive interaction after contextual review,
+including injection probes, reconnaissance, enumeration, and fuzzing. Actions
+judged destructive or persistent are blocked.
+
+## Disabling Safety
+
+Use the explicit dangerous opt-out only when external containment makes it
+necessary:
+
+```bash
+strix --target https://example.test --dangerously-disable-safety
+```
+
+This disables both action review and workspace isolation. Local directories are
+mounted live and writable. A run created with safety disabled requires the flag
+again when resumed; a guarded run cannot be downgraded while resuming.
+
+## Contextual Review
+
+Before an ambiguous shell or browser action executes, Strix compiles a frozen
+evidence packet containing the effective command, target scope, relevant script
+source and imports, prior tool-call evidence, browser snapshot context, and
+workspace persistence details.
+
+The safety model may decide immediately or make exactly one `run_inspection`
+tool call. That call runs a Python standard-library analysis script in a
+separate networkless, read-only container over the frozen evidence. For an
+incomplete packet in the interactive TUI, the reviewer must use that call to
+pinpoint the missing evidence and determine what the available artifacts still
+establish. If the tool is used, the model's next response must be the final
+decision.
+
+That single call can request explicit files or trailing-slash directories under
+`/workspace`. Strix uses fixed read/list primitives to freeze bounded regular
+files, directory listings, bytes, and digests into the evidence bundle, skipping
+symlinks and special files, and returns bounded previews to the reviewer. The same call may
+run a networkless analysis script over the augmented read-only bundle. The
+reviewer never executes model-authored commands in the live workspace, and the
+collected files become part of final fingerprint revalidation.
+
+Evidence acquisition gaps and reviewable uncertainty are distinct. Missing,
+unreadable, truncated, or unfrozen bytes are hard gaps and cannot support an
+automatic allow. When all relevant code and inputs are frozen but values such as
+a request destination or subprocess argument require correlation, the packet is
+`reviewable`; one successful inspection may resolve and allow it without asking
+the user. Only unresolved ambiguity is deferred.
+
+The review is bounded to at most two model turns and one inspection call.
+Timeouts, malformed decisions, a second tool call, and reviewer failures fail
+closed.
+
+In the interactive TUI, the reviewer can defer when the evidence still leaves
+genuine ambiguity about whether an exact action is dangerous. This includes an
+incomplete packet after the one inspection call has identified its unresolved
+gaps. Strix then pauses that tool call and asks the user to approve or deny it.
+The prompt shows the risk, the tool, and a preview of the command and reason;
+press `e` to expand the full command and reason and scroll them with the arrow
+keys. Denial is selected by default, Escape denies, and the request waits until
+it is answered, the agent is stopped, or Strix exits. Approval applies only to
+the frozen call shown in the prompt; actions too large to display exactly must
+be split into smaller tool calls. Deterministic blocks, review errors, and
+actions confidently judged dangerous cannot be overridden.
+
+The prompt also offers **Approve All**, which approves the pending call and then
+turns review off for the rest of the run — every later action runs unreviewed,
+exactly as if the scan had started with `--dangerously-disable-safety`. A
+standing "review off" flag on the status row marks that the run is no longer
+being checked. Use it only when external containment already bounds the blast
+radius.
+
+Approval prompts are scoped to their owning agent. The agent list marks the
+waiting owners with yellow indicators; select each agent to see and resolve its
+own prompt. Multiple agents can wait for independent approvals at the same time,
+and resolving one does not hide or block the others. You can continue navigating
+the agent list with the keyboard or mouse while approvals are pending, and
+returning to an owner reopens its prompt with Deny selected.
+
+Non-interactive runs have no human approval channel. Ambiguity, incomplete
+evidence, and low-confidence decisions continue to block, preserving
+fail-closed autonomous behavior.
+
+The reviewer judges an action by its effect, not by the technique it uses or by
+whether a hostname appears in target scope. A read-only injection probe (a boolean,
+`UNION SELECT`, or time-based payload), a reflected-input test, or recon passes;
+a payload that writes or destroys (`DROP`, `DELETE`, `INSERT`, `INTO OUTFILE`,
+stacked statements, command execution), a mutating request, or any persistent
+change is blocked or, in the TUI, deferred when its effect is genuinely ambiguous.
+
+Scope still controls what Strix actively tests, but the safety reviewer is not a
+scope enforcement layer. Ordinary passive requests to research services such as
+`crt.sh`, DNS and WHOIS, package registries, search, and public documentation are
+allowed when they support an authorized target. Those services do not become
+targets for scanning or exploitation.
+
+## Deterministic Rules
+
+Some outcomes never reach the model. Destructive commands, environment
+overrides that change which code an interpreter loads (`PYTHONPATH`,
+`LD_PRELOAD`, `AGENT_BROWSER_SESSION`, and similar), and blocked browser actions
+are refused outright. A small set of
+read-only commands is allowed outright, but only when its options are also
+read-only: `rg --pre` and anything else that hands the command another program
+to run goes to review instead.
+
+Browser observation commands are allowed outright only in the form that just
+reads: `tab` lists tabs, but `tab new <url>` navigates and `tab close` discards
+page state, so a grouped verb with a subcommand goes to review.
+
+Commands that wrap another program (`sudo`, `timeout`, `xargs`, `nohup`, and
+similar) cannot be resolved to a single effective action before dispatch. They
+fail closed in non-interactive runs; where the TUI can present a human decision,
+the reviewer first inspects and explains the unresolved action. Prefer issuing
+the underlying command as its own `exec_command` call. Interactive `write_stdin`
+payloads remain blocked because their effect depends on live process state and
+buffered input.
+
+## Scripts
+
+When a command executes a script, Strix reads the current entrypoint and local
+Python imports without importing or running them. Inline `python -c` source is
+analyzed the same way. Absolute imports resolve against the entrypoint's
+directory and relative imports against the importing module's package, and an
+imported name is followed as a submodule as well as an attribute, so the whole
+local closure is inspected. Decisions bind to content hashes. Dynamic code
+execution, import-path mutation, unresolved generated commands, oversized
+dependency closures, entrypoints outside `/workspace`, and unsupported evidence
+make the packet incomplete. Headless runs block; interactive runs use the one
+inspection call before any human deferral.
+
+Literal files read by Python through `open()`, `Path.read_text()`,
+`Path.read_bytes()`, or read-mode `Path.open()` are frozen as input artifacts,
+including simple string and `Path` assignments. Relative workdirs resolve below
+`/workspace`, matching actual sandbox execution. A resolvable script in a later
+compound-command segment is frozen too; create-and-execute chains remain
+blocked.
+
+A command that runs code Strix cannot resolve to an inspectable script — an
+unrecognized interpreter, or an interpreter given no script — is never allowed
+automatically. It is blocked headlessly or inspected and presented for an
+explicit TUI decision.
+
+When a command reads a workspace data file — through input redirection
+(`while read … done < hosts.txt`) or a target-list flag (`ffuf -w words.txt`,
+`httpx -l hosts.txt`) — that file's contents are attached to the packet so the
+reviewer can assess the exact entries, queried hosts, or fuzz inputs instead of
+blocking because it cannot see them. Redirect parsing respects shell quoting,
+escaping, comments, heredocs, and process substitutions. Referenced files under
+`/workspace` are read. Missing, unreadable, outside-workspace, over-limit, or
+truncated inputs make the packet incomplete and follow the headless-block or
+interactive-review behavior above.
+
+Evidence collection is serialized briefly to produce a consistent snapshot;
+model review and human waiting remain concurrent. If another agent changes the
+workspace during review, Strix refreshes and compares the actual evidence
+fingerprint. Unchanged evidence executes without interruption. Changed scripts,
+dependencies, inputs, or missing-file observations are automatically reviewed
+again, with a new approval only when the refreshed review still needs one.
+
+Browser automation inside scripts is blocked in safety modes. Issue browser
+operations as individual raw `agent-browser` commands so each action can be
+reviewed against the current snapshot and element references.
+
+Commands that create and execute code in one shell expression should be split
+into separate creation and execution calls.
+
+## Browser Commands
+
+Strix continues to use the raw `agent-browser` CLI. In safety modes it assigns
+an isolated browser session per agent and rejects model-supplied session,
+profile, or CDP overrides.
+
+Interactions with element references require a prior recorded snapshot. A
+snapshot taken before a navigation or any other page-changing action is stale:
+the action is blocked and the agent must snapshot again.
+
+Composite operations such as `auth login`, arbitrary `eval`, browser state
+persistence, and uploads are blocked. Guarded login should use explicit fill
+and submit steps with credentials supplied in the initial user instruction.
+
+## Workspace Isolation
+
+By default, user-owned local directories are copied into:
+
+```text
+strix_runs/<run>/.state/workspaces/<name>
+```
+
+The copy is mounted writable, while the original source remains unchanged.
+`.git`, `.agents`, and `.codex` inside the copy stay read-only: they carry
+repository and agent-instruction state that survives `--resume`. Copies are
+retained for resume. Repository targets are already cloned into a disposable
+location and do not need another copy.
+
+In-tree symlinks are materialized. Dangling, cyclic, device, and out-of-tree
+symlinks are omitted. Files are copied rather than hard-linked.
+
+## Limitations
+
+Contextual review reduces accidental harmful actions; it is not a complete
+network containment boundary. Arbitrary dynamic programs, raw sockets, or
+processes that ignore proxy settings cannot always be predicted statically.
+Unresolvable behavior blocks in safety modes.
+
+Deterministic rules cover the cases listed above. Every other command is judged
+by the safety model against compiled evidence, so a tool whose effects are not
+statically recognizable — a scanner or exploit framework that mutates the
+target through its own protocol, for example — rests on that judgment rather
+than on a rule. Strong containment additionally requires externally enforced
+egress policy and reduced sandbox privileges.

+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.

+# 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.

+# 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. |

+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**.

+
+# 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**.

@@ -216,10 +239,31 @@ VALIDATION REQUIREMENTS:
 - 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`.

+  short.
+
+A coverage claim is an attestation, so conflating the two would be the worst
+possible failure: a hallucinated "tested and clean" is strictly less honest
+than no coverage record at all. Every entry therefore carries its ``source``,
+and machine-observed facts contradict rather than confirm — an agent that
