 `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:

-```
-
-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.

 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.

-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.

-  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.

-- For reasoning models (e.g. qwen3), disable the model's **thinking** mode — thinking left on frequently pushes the tool call into the text `content` instead of the structured `tool_calls` field. Turn it off on the Ollama side (a non-thinking model variant, or `think: false` in the model's parameters / `Modelfile`).
-- Raise **`num_ctx`** to at least 16k–32k. Strix sends a large system prompt plus many tool schemas; at Ollama's small default context the tool definitions are truncated out of the prompt and the model stops emitting valid calls. A short test prompt can look fine while a real scan fails, so set this explicitly rather than inferring it from a quick check.

-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.

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. |
-| 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.

-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.

-
-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**.

 AUTHORIZATION STATUS:

@@ -232,31 +216,10 @@ 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. It is scoped to this scan and nothing carries over from an earlier run, so `found: false` means no agent on this run has derived one yet. 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`.
