feat: place caller-provided files into the sandbox workspace (extra_files, --workspace-file) (#1085)

* add extra-files plumbing so orchestrators can drop single files into the sandbox workspace

* reject extra-file paths that collide with a local source tree

* add --workspace-file so CLI users can place files in the sandbox workspace

* reject repeated and control-character workspace paths

* revalidate persisted workspace files when resuming a run

* drop the workspace-file size limit

+# 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)
+
+**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).

+## 🤖 Use Strix from Your Coding Agent
+
+Strix is agent-ready. Give Claude Code, Cursor, Codex, or any [SKILL.md-compatible](https://agentskills.io) agent the ability to run pentests, fix findings, and set up CI scanning:
+
+```bash
+npx skills add usestrix/strix
+```
+
+This installs four skills: **penetration-testing-with-strix** (run headless scans and read results), **managed-pentesting-with-strix** (drive the managed [app.strix.ai](https://app.strix.ai) platform via REST — no local Docker or LLM key), **fix-security-vulnerabilities-with-strix** (remediate + re-scan to verify), and **ci-security-scanning-with-strix** (PR scanning in CI). Agents can run Strix two ways with the same engine — the open-source CLI locally, or the managed cloud when there's no local infra — and read [`AGENTS.md`](AGENTS.md) for a quick reference, [docs.strix.ai/llms.txt](https://docs.strix.ai/llms.txt) for the CLI docs, and [docs.app.strix.ai](https://docs.app.strix.ai) for the API.

+title: "Coding Agents"
+description: "Use Strix from Claude Code, Cursor, Codex, and other AI agents"
+---
+
+Strix is built to be driven by AI coding agents. Install the official agent skills and your agent knows how to run pentests, remediate findings, and wire Strix into CI.
+
+## Install the Skills
+
+Works with any agent that supports the open [SKILL.md standard](https://agentskills.io) — Claude Code, Cursor, Codex, Gemini CLI, OpenCode, and dozens more:
+
+```bash
+npx skills add usestrix/strix
+```
+
+| Skill | What your agent learns |
+|-------|------------------------|
+| `penetration-testing-with-strix` | Run headless scans against code, URLs, domains, or IPs — self-hosted CLI or managed cloud — with budget caps, and read the results |
+| `managed-pentesting-with-strix` | Drive the managed [app.strix.ai](https://app.strix.ai) platform over REST — no local Docker or LLM key needed |
+| `fix-security-vulnerabilities-with-strix` | Triage findings, fix root causes, and re-run Strix to verify each fix |
+| `ci-security-scanning-with-strix` | Add PR security scanning to GitHub Actions or any CI (self-hosted CLI or managed app) |
+
+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.
+```

+## 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

+
+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.

Covers both the self-hosted open-source CLI (runs in your runner) and the managed app.strix.ai platform (GitHub/GitLab app or API, no runner infra).

+# 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 don't 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, e.g. `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/${{ github.base_ref }}` in GitHub Actions rather than a hard-coded `origin/main`, since repos use different default branches.
+- Exit codes: `0` pass, `2` vulnerabilities found (fails the job), `1` setup error.
+- The runner needs Docker (default GitHub-hosted Ubuntu runners have it).
+- **Size the budget so the scan completes — don't let it fail open.** A `0` exit means "no validated vulnerabilities in what was analyzed"; if `--max-budget` is hit before the diff is fully covered, the scan wraps up early and can still exit `0`. The "Fail unless the scan completed" step above narrows the gap: `strix_runs/<run>/run.json` is `"stopped"` when the scan was cut off at the hard budget limit without a final report. It is not a complete guard — the agents get graduated wrap-up warnings before that limit, and a run that wraps up on a warning still calls `finish_scan` and records `"completed"` with partial coverage. So keep that step in any pipeline that gates merges **and** give the scan real headroom (compare `run.json`'s `llm_usage.cost` against `--max-budget`; if it ran right up to the cap, raise it). For a `quick` diff-scoped PR scan `--max-budget 10` is usually ample, raise it for large diffs.
+
+### Optional: upload findings to GitHub code scanning
+
+Strix writes SARIF 2.1.0 to `strix_runs/<run>/findings.sarif`:
+
+```yaml
+      - name: Upload SARIF
+        if: always()
+        uses: github/codeql-action/upload-sarif@v3
+        with:
+          sarif_file: strix_runs
+```
+
+## Other CI systems
+
+Any pipeline works the same way — install, set the two env vars, run headless:
+
+```bash
+curl -sSL https://strix.ai/install | bash
+# Resolve the PR's base branch robustly (use your CI's base-branch variable if it
+# has one, e.g. GitHub Actions: origin/${{ 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/${BASE_BRANCH:-main}"
+# Fail loudly rather than silently narrowing scope (e.g. to HEAD~1, which on a
+# multi-commit branch would scan only the last commit and let earlier ones pass).
+if ! git rev-parse --verify --quiet "$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.

+
+# 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 (e.g. parameterize all queries, don't blocklist one string; enforce authorization in the handler, don't hide 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 doesn't 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 "$scan_id"
+```
+
+Useful `CreateScanRequest` fields:
+
+| Field | Purpose |
+|---|---|
+| `engagement_type` | `live_test` (default), `code_review`, `internal_infra`, `compliance_pentest` |
+| `domain_ids` / `repository_ids` / `internal_targets` | targets (at least one) |
+| `domain_paths` / `repository_branches` | narrow to specific paths / branches |
+| `credentials` | authenticated scanning, incl. `mfa_method` (`totp`/`email_otp`/…) + `totp_secret` |
+| `headers` | extra HTTP headers (e.g. API keys) for the target |
+| `focus` / `concerns` / `context` | steer the agents |
+| `upload_ids` | attach uploaded source/docs archives for white-box context |
+| `notify_on_completion` / `notification_emails` | email when done |
+
+Response is `{ scan_id, title, status }` with `status` = `pending`.
+
+## 3. Poll to completion
+
+`GET /scans/{scanId}` (`scans:read`). Status flow: `pending → running → completed` (or `failed` / `cancelled`). Poll on an interval — scans take minutes to hours; don't block.
+
+```bash
+while :; do
+  s=$(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 (e.g. `scan.completed`, `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 — don't try to bypass it.

+# 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, don't 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 / doesn't 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:** e.g. 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."
+
+# Large monorepo: bind-mount instead of copying
+strix -n --mount ./huge-monorepo
+```
+
+Key flags:
+
+| Flag | Meaning |
+|---|---|
+| `-t, --target` | URL, repo URL, local path, domain, or IP. Repeatable. |
+| `-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. |
+| `--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/`. |
+
+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>/`:
+
+| File | Contents |
+|---|---|
+| `penetration_test_report.md` | Executive report — read this first. |
+| `vulnerabilities/*.md` | One file per validated finding, with PoC and remediation. |
+| `vulnerabilities.json` / `vulnerabilities.csv` | All findings as structured JSON / CSV index. |
+| `findings.sarif` | SARIF 2.1.0 for GitHub code scanning / ASPM ingestion. |
+| `run.json` | Run metadata, status, targets, usage/cost. |
+
+---
+
+# 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 haven't. If Docker/local prerequisites aren't 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.

+- Sweep object ACLs for `allUsers` and `allAuthenticatedUsers`, including objects made public by Admin SDK `makePublic()` or writers using `public: true`. Per-object public ACLs persist after Firebase rules are tightened and can remain on older prefixes.
