Merge branch 'main' into fix/caido-boot-wait-deadline

Resolve conflicts:
- session_manager.py: keep main's concurrent CaidoBootstrapHandle wrapper,
  thread the configurable caido_boot_wait_s budget into bootstrap_caido().
- test_caido_bootstrap.py: combine both test suites (deadline/timeout-cap
  probe tests + connect-failure teardown tests); rename the login-only
  fake session to _FakeLoginSession to avoid the name clash.

   ```
-  - API docs: https://docs.app.strix.ai (OpenAPI: https://docs.app.strix.ai/openapi.json).
+  - Account setup runs from the CLI too: `strix cloud workspaces list|create|use` (`workspace` is an alias and `use` accepts a displayed number, name, or ID), `strix cloud session scopes|scopes set`, `strix cloud org members invite`, `strix cloud billing subscribe --plan strix_cloud`, `strix cloud billing portal`, `strix cloud integrations install github`, and `strix cloud domains verify <id>`. Workspace switching preserves the server-side profile and can never widen past the login ceiling; ordinary switches do not reprompt. The last four end at a person: the command prints a link or a DNS record for the user to open or add, and it never completes the payment, installation, or DNS change for them.
+  - Every REST operation has a `strix cloud <resource> <verb>` command. Run `strix cloud` to list them. Output is JSON when stdout is not a terminal (or with `--json`), and there are no prompts without a TTY. Binary downloads are the exception: redirect raw bytes intentionally, or combine `--output FILE --json` for structured download metadata. Exit codes: `0` success, `1` error, `2` usage, `4` auth or plan limit, `5` payment required. `--token` or `STRIX_API_TOKEN` is a stateless override and never replaces stored auth; set `--workspace-id`/`STRIX_WORKSPACE_ID` for an override CLI session. `--data` adds extra request fields as JSON, and accepts `@file` or `-` for standard input.
+  - Local source uploads require `uploads:write`. For an agent/CI handoff, review `scans start --source . --dry-run --show-files --json`, capture `source.archive_sha256`, then rerun with the same `--source`, `--exclude`, and `--include-*` selection flags plus `--approve-sha256 HASH`. A changed snapshot is rejected. `--yes` approves only the snapshot built in that invocation, so reserve it for a deliberate human or one-shot approval rather than a digest-bound two-step handoff.
+  - Git ignores, hidden files, `.git`, symlinks, dependency/build output, secret-like filenames, and nested archives are excluded by default; `.strixignore` and `--exclude` narrow the manifest further (a trailing `/` excludes a directory subtree). Limits: 20,000 files, 25 MiB/file, 250 MiB expanded, 50 MiB compressed. Source-only infers `code_review`; source plus a domain infers `live_test`.
+  - The temporary local archive is always removed. A staged upload is deleted after a definitive rejection, but retained when a network error, `5xx`, malformed success response, or interruption leaves the scan launch ambiguous. JSON reports its `upload_id` with `launch_outcome_unknown: true`, or with `cleanup_unknown: true` when automatic deletion cannot be confirmed. Check `scans list` before retrying; if no scan is linked, run `uploads delete UPLOAD_ID`.
+  - Non-Enterprise scans consume the scope estimate (a default-tier source-only review currently starts at 60 credits); Enterprise scans are plan-included. A rejected launch does not consume credits.
+  - Human output is compact and numbered; non-TTY output and `--json` retain full records. Enable tab completion with `source <(strix completions zsh)` (or `bash`), or `strix completions fish | source`.
+  - The REST API works directly too: https://docs.app.strix.ai (OpenAPI: https://docs.app.strix.ai/openapi.json).

-
+strix auth login chatgpt             # sign in with your ChatGPT account

+#### Use the managed platform: `strix cloud`
+

+
+```bash
+strix cloud login                                  # browser sign-in, one credential per install
+strix cloud scans start --source . --yes --wait    # scan local code, approving the upload
+strix cloud scans start --engagement-type live_test --domain-ids <uuid> --wait
+strix cloud vulns list --severity critical
+```
+
+Every [REST API](https://docs.app.strix.ai) operation has a matching `strix cloud <resource> <verb>` command. Run `strix cloud` to list the resources, and add `help` to a resource to list its verbs. Output is JSON when stdout is not a terminal or when you pass `--json`. Binary downloads are the exception: redirect the raw bytes, or combine `--output FILE --json` for download metadata.
+
+See the [cloud CLI documentation](https://docs.strix.ai/cloud/cli) for scopes, workspaces, billing, and source-upload options.
+
+#### 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 local `stdio` servers or remote `http` servers:
+
+```json
+[
+  {
+    "name": "github",
+    "transport": "http",
+    "url": "https://api.githubcopilot.com/mcp/",
+    "auth": { "kind": "bearer", "token": "your-token" },
+    "allowed_tools": ["list_issues"]
+  }
+]
+```
+
+Each server's tools are namespaced by `name`, for example `github_list_issues`. See the [MCP documentation](https://docs.strix.ai/integrations/mcp) for the full schema, tool filtering, and `stdio` servers.
+

+description: "Drive app.strix.ai from the terminal with strix cloud"
+---
+
+The `strix cloud` commands drive the managed platform ([app.strix.ai](https://app.strix.ai)) from the terminal. You do not need Docker or an LLM key.
+
+## Sign In
+
+Sign in once with the browser device flow. The sign-in creates your account and workspace on first use, and it stores a personal API token in `~/.strix/platform-auth.json`.
+
+```bash
+strix cloud login                         # browser approval, then workspace and scope profile
+strix cloud login --workspace "My Team"   # select a workspace by name or ID
+strix cloud whoami                        # local account and workspace status
+strix cloud session                       # verify the remote session and consent ceiling
+strix cloud logout                        # revoke remotely, then remove the local token
+```
+
+A browser sign-in creates one reusable credential for each CLI installation. A second sign-in on the same installation replaces the secret instead of adding another key. `strix cloud logout` revokes the server session before it deletes the local token. Use `--local-only` when you cannot reach the server.
+
+## Scopes
+
+The default **Recommended** preset covers normal scan work, local source uploads, workspace switching, and user-approved credit top-ups. It excludes credential creation, so request `tokens:write` when you need it.
+
+```bash
+strix cloud login --scopes scans:read scans:write uploads:write billing:read
+strix cloud login --scope-profile minimal   # also accepts recommended or full
+strix cloud session scopes                  # granted scopes and the login ceiling
+strix cloud session scopes set minimal      # narrow without another browser sign-in
+```
+
+A workspace switch keeps the credential and its expiry, preserves the server-side scope preference, and caps access by the target role. A switch can never exceed the login consent ceiling. Each process pins the workspace it started with, so a concurrent switch fails safely instead of sending a stale command to another organization.
+
+## Commands
+
+Every operation of the [REST API](https://docs.app.strix.ai) has a matching command in the form `strix cloud <resource> <verb>`.
+
+```bash
+strix cloud                                   # list all resources
+strix cloud scans                             # run the safe default (scans list)
+strix cloud scans help                        # list the verbs of a resource
+strix cloud domains add --domain example.com --asset-type web_app
+strix cloud scans start --engagement-type live_test --domain-ids <uuid> --wait
+strix cloud vulns list --severity critical
+strix cloud credits                           # credit balance
+```
+
+Write commands take request fields as flags. Every write command also accepts one JSON object with `--data`:
+
+```bash
+strix cloud scans start --data '{"engagement_type":"code_review"}'   # literal JSON
+strix cloud scans start --data @request.json                         # read a file
+cat request.json | strix cloud scans start --data -                  # read standard input
+```
+
+`--token` and `STRIX_API_TOKEN` are stateless overrides for a single command, and they never replace the stored sign-in. Pair a CLI-session override with `--workspace-id` or `STRIX_WORKSPACE_ID`.
+
+## Workspaces And Account Setup
+
+```bash
+strix cloud workspaces list                       # numbered list; workspace is also accepted
+strix cloud workspaces create --name "My Team"    # needs admin and organizations:write
+strix cloud workspaces use 2                      # switch by list number, exact name, or ID
+strix cloud billing topup --credits 20 --yes      # approve an agent payment after HTTP 402
+strix cloud billing subscribe --plan strix_cloud  # opens the hosted checkout page
+strix cloud billing portal                        # opens the billing portal
+strix cloud integrations install github           # opens the app installation page
+strix cloud domains verify <domain-id>            # prints the DNS record to add
+```
+
+The last four commands end at a person. Strix creates the link, opens the browser for an interactive terminal, and always prints the URL. The user enters the card, approves the installation, or adds the DNS record. Pass `--no-browser` to print the URL only.
+
+## Output And Exit Codes
+
+The commands work for people and for agents. Terminal output favors names, branches, lifecycle states, and numbered selectors. Redirected output, and `--json`, preserve the complete machine-readable record.
+
+- Human lists keep the selectors that follow-up commands need, and they omit internal organization and user IDs. A selector that is too long for the compact table is repeated losslessly in a copyable block.
+- Paginated lists print the next `--page` or `--offset`. Detail views keep useful prose within a safe terminal bound, so use `--json` for the complete record.
+- Token lists separate API keys from named CLI device sessions.
+- Binary downloads are the exception to JSON output. Redirect the raw bytes on purpose, or use `--output FILE --json` to write the file and receive structured download metadata.
+- There are no prompts when stdin is not a terminal.
+
+Exit codes: `0` success, `1` error, `2` invalid usage, `4` authentication or plan limit, `5` payment required.
+
+## Credits And Plan Limits
+
+Non-Enterprise scans consume the deterministic estimate shown for their scope. A source-only code review at the default `ultra` tier currently starts at 60 credits. Enterprise scans are plan-included and do not consume the credit wallet.
+
+Report downloads need Enterprise, schedules need Pro, and billing writes need an admin token. A plan block exits `4`. An insufficient credit wallet exits `5` without the creation of a scan and without a charge.
+
+## Local Source Scans
+
+See [Scan Local Source](/cloud/overview#scan-local-source) for the upload approval flow, the exclusion rules, and the size limits.
+
+## Tab Completion
+
+Enable native tab completion once for each shell session:

+In a Git repository, Strix includes tracked files and untracked files that are not ignored. Hidden files, `.git`, symlinks, dependencies and build output, secret-like filenames, and nested archives are excluded by default. Use `.strixignore` or repeat `--exclude GLOB` for project-specific exclusions. `--include-hidden`, `--include-sensitive`, and `--include-archives` are explicit opt-ins.
+
+The CLI limits individual files, total expanded bytes, archive bytes, and file count. For an agent or CI handoff, repeat the same `--source`, `--exclude`, and `--include-*` flags with `--approve-sha256`; Strix refuses the upload if the rebuilt archive differs from the reviewed digest. `--yes` is a one-invocation approval for the snapshot built at that moment, not a digest-bound two-step approval.
+
+The temporary local archive is always removed. After a definitive launch rejection, Strix also deletes the staged remote upload. If a network error, server error, or interruption makes the launch outcome ambiguous, it retains the upload and reports its ID; check `strix cloud scans list` before retrying, then delete an unlinked upload with `strix cloud uploads delete UPLOAD_ID`.

 ## 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).
+- **Cloud CLI** — `strix cloud` prints JSON when stdout is not a terminal (or with `--json`), never prompts without a TTY, and exits with `0` (success), `1` (error), `2` (usage), `4` (authentication required), or `5` (payment required). Credit top-ups pay the Stripe machine-payment challenge with an agent wallet (`strix cloud billing topup --credits N --yes`). Account setup also runs from the CLI: `strix cloud workspaces list|create|use`, `strix cloud org members invite`, `strix cloud billing subscribe`, `strix cloud billing portal`, and `strix cloud integrations install github`. The last three print a hosted link the user opens to finish the payment or approve the installation.
 - **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.

+title: "MCP Servers"
+description: "Connect your own MCP servers and expose their tools to the agent"
+---
+
+Strix can connect to [Model Context Protocol (MCP)](https://modelcontextprotocol.io) servers you list and expose their tools to the agent during a run. Use this to let the agent read how your system is actually built instead of inferring it from the outside.
+
+A few things it pays off for:
+
+- **A database server.** The agent can read the schema and access policies and see tables left readable without them, rather than guessing from responses.
+- **A hosting or infrastructure server.** Deployments, domains and environment variable names tell it what is really running, so it tests what exists instead of what it discovered by crawling.
+- **An issue tracker.** Known and accepted risks stop the agent re-reporting findings you already triaged.
+- **A logging server.** Reading logs lets it confirm an exploit attempt actually landed instead of inferring it from a status code.
+
+## Setup
+
+Create the file `~/.strix/mcp-servers.json`. It holds a JSON list of the servers you want the agent to reach. Each entry is either a local `stdio` server that Strix launches as a subprocess, or a remote `http` server.
+
+Create the directory if it does not exist, then write the file:
+
+```bash
+mkdir -p ~/.strix
+```
+
+Paste the servers you want into `~/.strix/mcp-servers.json`. The example below shows one of each transport: a local filesystem server over `stdio` and a remote GitHub server over `http` with a bearer token:
+
+```json
+[
+  {
+    "name": "local_fs",
+    "transport": "stdio",
+    "command": "npx",
+    "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/project"]
+  },
+  {
+    "name": "github",
+    "transport": "http",
+    "url": "https://api.githubcopilot.com/mcp/",
+    "auth": { "kind": "bearer", "token": "your-token" },
+    "allowed_tools": ["list_issues"]
+  }
+]
+```
+
+Strix reads this file at the start of each run. There is no default file, so no MCP tools are loaded until you create it. Edit `command`, `args`, `url`, and `token` to match your own servers.
+
+## Fields
+
+<ParamField path="name" type="string" required>
+  A short label for the connection. Each server's tools are namespaced by
+  `name` (for example `local_fs_read_file`), so two servers can offer the same
+  tool name without colliding.
+</ParamField>
+
+<ParamField path="transport" type="string">
+  `stdio` for a local subprocess server, or `http` for a remote server.
+</ParamField>
+
+<ParamField path="command" type="string">
+  For `stdio` servers: the executable Strix launches (for example `npx`).
+</ParamField>
+
+<ParamField path="args" type="array">
+  For `stdio` servers: the arguments passed to `command`.
+</ParamField>
+
+<ParamField path="url" type="string">
+  For `http` servers: the server endpoint URL.
+</ParamField>
+
+<ParamField path="auth" type="object">
+  For `http` servers that need a bearer token:
+  `{ "kind": "bearer", "token": "your-token" }`.
+</ParamField>
+
+<ParamField path="allowed_tools" type="array">
+  Restrict which tools the agent can call. Omit it to expose every tool the
+  server offers, or set it to a list of tool names to allow only those. Strix
+  does not decide for you which of a server's tools only read and which change
+  things, so run the server in its own read-only mode if it has one.
+</ParamField>
+
+<ParamField path="notes" type="string">
+  Free-text notes for the agent about what this connection is and how you want
+  it used, for example "Staging analytics database, read-only, prefer aggregate
+  queries." When set, the notes are given to the agent at the start of the run
+  as a description of the connection.
+</ParamField>
+
+## Choosing connections per run
+
+By default every connection in the file is used on each run. To narrow it for a
+single run without editing the file, use either flag (both repeatable):
+
+```bash
+strix --mcp-server github -t ...        # use only the named connection(s)
+strix --mcp-exclude staging-db -t ...   # use everything except the named one(s)
+```
+
+`--mcp-server` keeps only the connections you name; `--mcp-exclude` drops the
+ones you name. Connection names must be unique in the file; if two entries share
+a name, the first is kept and the rest are ignored.
+
+## Pointing at a different file
+
+To read the config from another path instead of `~/.strix/mcp-servers.json`, either pass `--mcp-config <path>` on the command line:
+
+```bash
+strix --mcp-config ./mcp-servers.json -t ...
+```
+
+or set the `STRIX_MCP_CONFIG` environment variable to that path. The flag takes precedence when both are given.
+
+## Startup confirmation
+
+When servers are configured, Strix prints a one-line summary at scan startup, for example `MCP: connected 1 server (14 tools): local_fs`, so you can confirm your servers connected.
+
+## Seeing the calls
+
+Each call the agent makes to one of your servers is shown with its own icon and
+labelled with the connection it went out to, in the terminal and in the run
+viewer (`strix view`), so a call that left Strix for a server you connected is
+easy to pick out of a transcript. The terminal shows the call and its arguments;
+results can be large and arbitrary, so read them in the viewer, which shows a
+preview you can expand.
+
+## Behavior
+
+- The config file is optional. Without it, a run simply gets no MCP tools.
+- A server that fails to connect is skipped and logged, and the run continues without it.
+- A single malformed entry is skipped without blocking the valid ones.

+
+Instructions become part of the prompt. To give Strix a file to work with, such

+
+```bash

+```
+
+Repeat the option for every file you want to place. Strix lists the files in the

+
+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

+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. For a run with no Docker and no LLM key, the same binary drives the managed platform: `strix cloud login`, then `strix cloud scans start ...` (details in **managed-pentesting-with-strix**).
+
+## 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. For a run with no Docker and no LLM key, the same binary drives the managed platform: `strix cloud login`, then `strix cloud scans start ...` (details in **managed-pentesting-with-strix**).
+
+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. For a run with no Docker and no LLM key, the same binary drives the managed platform: `strix cloud login`, then `strix cloud scans start ...` (details in **managed-pentesting-with-strix**).
+
+## 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.

+# Strix Cloud (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`
+There are two equivalent interfaces. Prefer the CLI:
 
-## Setup
+- **`strix cloud` CLI** — every REST operation has a command in the form `strix cloud <resource> <verb>`. Install with `curl -sSL https://strix.ai/install | bash`. Run `strix cloud` to list all resources and `strix cloud <resource> help` (or `-h`) to list a resource's verbs; a bare resource with a safe read operation runs its documented default.
+- **REST API** — base URL `https://app.strix.ai/api/v1`, `Authorization: Bearer <token>` on every request. Full reference: **[docs.app.strix.ai](https://docs.app.strix.ai)** · agent index: `https://docs.app.strix.ai/llms.txt` · OpenAPI: `https://docs.app.strix.ai/openapi.json`.
 
-- **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.
+The CLI is equally usable by agents and people. Output is complete JSON when stdout is not a terminal, or when you pass `--json`; terminal tables favor names, branches, lifecycle states, and numbered selectors. Human lists retain the selectors needed by follow-up commands but omit internal organization/user IDs; a selector too long for the compact table is repeated losslessly in a copyable block. Paginated lists print the next `--page` or `--offset`, and detail views preserve useful prose within a safe terminal bound; use `--json` for the complete record. Token lists label credentials as active, expired, or revoked. Binary downloads are the exception: redirect raw bytes intentionally, or use `--output FILE --json` to write the file and receive structured metadata. There are no interactive prompts when stdin is not a terminal. Exit codes: `0` success, `1` request/runtime error, `2` invalid usage, `4` authentication or plan limit, `5` payment required.
+
+Every resource group with a safe read operation has a useful default action, and `-h` or `help` always shows its verbs. Native tab completion includes resources, verbs, flags, workspace commands, and local paths:
+
+```bash
+source <(strix completions zsh)       # current zsh session
+source <(strix completions bash)      # current bash session
+strix completions fish | source       # current fish session
+```
+
+Write commands take request fields as flags. Every write command also accepts one JSON object with `--data`, which is the way to send fields that have no flag:
+
+```bash
+strix cloud scans start --data '{"engagement_type":"code_review"}'   # literal JSON
+strix cloud scans start --data @request.json                         # read a file
+cat request.json | strix cloud scans start --data -                  # read standard input
+```
+
+The platform enforces plan and role limits, and the CLI passes the platform message through. Report downloads need the Enterprise plan. Schedules need the Pro plan. Billing writes need an admin token. A blocked command exits with code `4`.
+
+## Setup: sign in
+
+Run the device sign-in. It creates the user's account and workspace on first use and stores a personal API token in `~/.strix/platform-auth.json`:
+
+```bash
+strix cloud login
+# Non-interactive least-privilege example:
+strix cloud login --scopes scans:read scans:write uploads:write billing:read vulnerabilities:read assets:read assets:write
+# Or use a stable named profile:
+strix cloud login --scope-profile recommended
+```
+
+The user approves the sign-in in the browser. With `--scopes` (and optionally `--workspace <name-or-id>`) there are no terminal prompts, so the command works from a non-interactive agent shell. In an interactive terminal without flags, the CLI offers a workspace picker and scope presets (Recommended, Full access, Minimal, Custom). Recommended covers ordinary scans, source uploads, workspace switching, and user-approved credit top-ups; it excludes `tokens:write`, which must be requested explicitly when credential management is required. Use explicit scopes for a narrower automation token.
+
+- `strix cloud whoami` is the fast local status. `strix cloud session --json` verifies the remote device session; `strix cloud session scopes` shows both effective access and the immutable login ceiling.
+- `strix cloud logout` revokes the remote session before removing the local token. On a network or server failure it keeps the token so the user can retry; `--local-only` deliberately skips revocation.
+- Every other `strix cloud` command uses the stored token automatically. `--token <token>` or `STRIX_API_TOKEN` is a stateless per-command override and never overwrites the stored account. For an override that is itself a CLI session, also pass `--workspace-id` or set `STRIX_WORKSPACE_ID`.
+- Never hardcode, log, or commit the token. Store it in an env var or the CI secret store.

+
+## 0. Credits & top-ups
+
+Non-Enterprise scans consume org credits. Enterprise engagements are plan-included and do not debit the wallet. Check the balance before a scan (`billing:read`):
+
+```bash
+strix cloud credits
+```
+
+When the balance is too low, buy credits with `strix cloud billing topup` (`billing:write`, admin token). The server answers the first request with **HTTP 402 and a machine-payment challenge** (Stripe Machine Payments Protocol). The CLI pays the challenge with the Stripe Link wallet client when Node.js is available — the user approves the spend in the [Link app](https://link.com/agents). The response returns the receipt (`credits_granted`, `duplicate`, `reference`) and the new balance.
+
+A default-tier source-only code review currently starts at 60 credits. Source uploads are not free: they launch an ordinary `code_review` and use the same deterministic scope estimator. The service checks the full balance before launch, reserves credits atomically only after validation succeeds, and does not create or charge a rejected scan. Retests and Enterprise scans are exempt.
+
+```bash
+strix cloud billing topup --credits 20 --yes   # explicit approval; skips the TTY prompt
+strix cloud billing topup --credits 20 --no-pay   # print the 402 challenge without paying
+```
+
+The default payment path is the Stripe Link wallet. When no wallet is connected, an interactive `strix cloud billing topup` starts the Link sign-in for the user and prints the verification link. The user approves the connection one time in the Link app, and then approves each payment there. No keys or variables are necessary. In a non-interactive process, the command stops and tells the user to connect the wallet at [link.com/agents](https://link.com/agents) or to use the hosted checkout link.
+
+In a non-interactive agent or CI process, payment never proceeds unless the command includes `--yes`. Show the challenge or estimated spend to the user and obtain approval before adding it. `--no-pay` always stops after printing the challenge.
+
+If the user does not want a wallet, create a hosted checkout link with `strix cloud billing subscribe --plan strix_top_up` and give the link to the user. The user pays in the browser.
+
+Automatic top-ups (admin): `strix cloud billing auto-topup` shows the setting. Enable it with:
+
+```bash
+strix cloud billing auto-topup update --enabled --topup-credits 20 --monthly-cap-credits 200
+```
+
+An omitted `--monthly-cap-credits` keeps the stored cap. Pass `--no-monthly-cap` to remove the cap.
+
+### Workspaces and account setup
+
+Manage workspaces with a personal token from `strix cloud login`:
+
+```bash
+strix cloud workspaces list                    # numbered name/role/current list
+strix cloud workspaces create --name "My Team"  # admin + organizations:write
+strix cloud workspaces use 2                   # displayed number, exact name, or ID
+strix cloud workspace use "My Team"            # singular `workspace` alias also works
+strix cloud session scopes                     # effective scopes + consent ceiling
+strix cloud session scopes set minimal         # narrow the session
+strix cloud org members invite --email dev@example.com --role analyst
+```
+
+`workspaces use` retargets the current personal token to a workspace the user already belongs to and stores the updated workspace metadata; the bearer secret and expiry stay unchanged. It does not reprompt during ordinary switches: the server preserves the chosen profile, enforces the immutable login ceiling, and caps effective scopes by the target role. Use `--scope-profile` or `--scopes` to narrow within that ceiling; broader consent requires `strix cloud login` again. The CLI pins each process to the workspace it started in, so concurrent shells fail with a recoverable conflict instead of silently crossing organizations.
+
+### Handoffs a person must finish
+
+Four steps end at the user. The command creates the link or the record and prints it. Strix opens the browser only in an interactive terminal. Pass `--no-browser` to print the URL only.
+
+```bash
+strix cloud billing subscribe --plan strix_cloud # hosted checkout page for the Cloud plan
+strix cloud billing portal                       # billing portal for the card and the plan
+strix cloud integrations install github          # GitHub App or Slack installation page
+strix cloud domains verify <domain-id>           # DNS record to add, then run it again
+```
+
+Give the printed URL or DNS record to the user and wait. Do not claim that the payment, the installation, or the DNS change is complete. Confirm the result afterwards with `strix cloud credits`, `strix cloud integrations list`, or `strix cloud domains list`. All four commands need an admin token, except `domains verify`, which needs `assets:write`.
+
+### Organization knowledge
+
+Agents can manage the organization knowledge base without the dashboard (`knowledge:read` / `knowledge:write`):
+
+```bash
+strix cloud knowledge list --search authentication
+strix cloud knowledge add --title "Authentication" --content "Staging uses SSO."
+strix cloud knowledge update <document-id> --content "Staging uses SSO and TOTP."
+strix cloud knowledge delete <document-id>
+strix cloud knowledge policies add --key staging-only --content "Never test production."
+strix cloud knowledge policies delete staging-only
+strix cloud knowledge repos entries usestrix/strix
+```
+
+Knowledge policy writes require an admin token. Repository names are passed as normal `owner/name` values; the CLI handles URL encoding. The `costs` and `llm-settings` commands target on-prem installations and return `404` on app.strix.ai.

-`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.
+For an agent or CI workflow, bind approval to the exact source snapshot that was reviewed. Run
+the dry run with the intended source-selection flags, review the manifest and selected paths,
+and capture `source.archive_sha256`. Then repeat the same `--source`, every `--exclude`, and
+any `--include-hidden`, `--include-sensitive`, or `--include-archives` flags with
+`--approve-sha256`:
 
 ```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
+strix cloud scans start --source . --exclude 'private/' --dry-run --show-files --json
+# After reviewing the output, capture its source.archive_sha256 value:
+SOURCE_SHA256="<reviewed source.archive_sha256>"
+# Repeat every source-selection flag unchanged; a source-only scan infers code_review.
+strix cloud scans start --source . --exclude 'private/' \
+  --approve-sha256 "$SOURCE_SHA256" --wait
 ```
 
+The CLI rebuilds the archive and refuses the upload if its SHA-256 no longer matches. `--yes`
+has deliberately narrower semantics: it approves only the snapshot built during that one
+invocation. Use it for a deliberate human or one-shot approval, not as the second half of a
+digest-bound agent/CI review. Without a TTY, a source upload requires either matching
+`--approve-sha256` approval or `--yes`; an interactive terminal can instead show the summary,
+the selected filenames when `--show-files` is set, and a `[y/N]` confirmation for its current
+snapshot.
+
+The default selection is privacy-conscious: in a Git worktree it includes tracked files plus untracked files that are not ignored; it honors `.gitignore`, excludes every hidden path component, always excludes `.git`, symlinks, dependencies/build output, secret-like filenames, and nested archives. Add project exclusions to `.strixignore` (one exclude glob per line) or repeat `--exclude GLOB`; a trailing slash such as `private/` excludes that directory subtree.
+
+The client refuses more than 20,000 files, a file over 25 MiB, more than 250 MiB expanded, or a ZIP over 50 MiB. The service then stream-inflates the ZIP and independently rejects malformed or unsupported entries, unsafe paths, too many entries, oversized entries, excessive expanded data, and oversized compressed input, so an untrusted client cannot bypass the ZIP-bomb controls by forging metadata.
+
+Only use `--include-hidden`, `--include-sensitive`, or `--include-archives` after the dry-run manifest shows that the scan needs them. Hidden and sensitive files are separate opt-ins: for example, including `.env` requires both `--include-hidden` and `--include-sensitive`.
+
+The CLI removes its private temporary local archive after every invocation. Once a remote
+upload is staged, a definitive scan rejection causes the CLI to delete it. A network failure,
+`5xx` response, malformed success response, or interruption after scan launch begins is
+ambiguous—the platform may have accepted the scan—so the CLI retains the upload and returns
+its `upload_id` with `launch_outcome_unknown: true`. If an automatic deletion attempt cannot
+be confirmed, it instead returns the retained `upload_id` with `cleanup_unknown: true`.
+Before retrying, run `strix cloud scans list` to avoid a duplicate scan or charge. If no scan
+is linked to the retained upload, remove it with `strix cloud uploads delete UPLOAD_ID`;
+linked uploads cannot be deleted.
+
+With no explicit type, source alone infers `code_review`. Any domain target wins and infers `live_test`, so source plus a deployed domain is the normal white-box live-test workflow. Pass `--engagement-type` when you need to override the inference.
+
+## 3. Wait for completion
+
+Pass `--wait` to `scans start` to poll until the scan reaches a final state, or poll yourself with `strix cloud scans get <scan-id>` (`scans:read`). Bound automation with `--wait-timeout SECONDS`; timeout exits cleanly without cancelling the remote scan. Status flow: `pending → running → completed` (or `failed` / `cancelled`). Scans take minutes to hours — poll on an interval, do not block indefinitely.
+
 ## 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`.

+# 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**. For a run with no Docker and no LLM key, the same binary drives the managed platform: `strix cloud login`, then `strix cloud scans start ...` (details in **managed-pentesting-with-strix**).
+
+## What is and is not testable by an agent
+
+Be straight with the user about this — claiming a clean sweep of all ten is misleading.
+
+| Category (2025) | Coverage |
+|---|---|
+| A01 Broken Access Control (incl. SSRF) | **Strong** — cross-user/tenant access, privilege escalation, IDOR, and SSRF (including blind, via out-of-band callbacks) are all exploit-validated. Needs two accounts plus a privileged one to prove the authorization half. |
+| A02 Security Misconfiguration | **Strong** — debug endpoints, verbose errors, permissive CORS, missing hardening, default credentials, exposed admin surfaces. |
+| A03 Software Supply Chain Failures | **Partial** — version fingerprinting, and vulnerable/outdated dependency review when source is supplied. Build-system and distribution-infrastructure compromise (the broader half of this category) is out of scope for a runtime scan — pair with SCA plus build-provenance controls. |
+| A04 Cryptographic Failures | **Partial** — transport config, unencrypted data in transit, secrets and tokens leaked in responses. At-rest crypto and key management need source or infra review. |
+| A05 Injection | **Strong** — SQL/NoSQL/command/template injection and XSS, exploit-validated. |
+| A06 Insecure Design | **Partial** — business-logic abuse (price/quantity tampering, workflow skipping, race conditions) is found where reachable; design intent still needs human review and threat modelling. |
+| A07 Authentication Failures | **Strong** — auth bypass, weak session/token handling, password-reset and MFA flaws. |
+| A08 Software or Data Integrity Failures | **Partial** — insecure deserialization and unsigned-update paths where reachable; CI/CD trust boundaries are not runtime-testable. |
+| A09 Security Logging & Alerting Failures | **Not testable from outside** — requires reviewing the logging and alerting pipeline. State this rather than reporting it as passed. |
+| A10 Mishandling of Exceptional Conditions | **Partial** — agents actively probe error handling and fail-open behavior (malformed input, forced errors, race and timeout conditions) and report what leaks or bypasses a control; exhaustive coverage of internal error paths needs source review. |
+
+For APIs, run the same exercise against the **OWASP API Security Top 10 (2023)** — API1 BOLA, API3 Broken Object Property Level Authorization (2019's excessive data exposure + mass assignment merged), API5 broken function-level authorization — using the **api-security-testing** skill.
+
+## Run it
+
+Maximum category coverage comes from giving the agents both the source and a running instance, plus credentials at two privilege levels:
+
+```bash
+strix -n \
+  -t https://github.com/org/app \
+  -t https://staging.example.com \
+  --scan-mode deep --max-budget 30 \
+  --instruction "OWASP Top 10:2025 assessment. Cover every category systematically and map each finding to its 2025 category id.
+Accounts: userA@example.com/<pw> (org 1), userB@example.com/<pw> (org 2), admin@example.com/<pw>.
+Prioritise A01 (cross-org access, privilege escalation, SSRF), A02, A05, A07, A10.
+Out of scope: /billing/*, outbound email."
+```
+
+- `--scan-mode deep` matters here: systematically walking ten categories is not a quick scan.
+- Without a second account, A01 results are structurally incomplete — say so in the report rather than leaving it implied.
+- Need an auditor-facing PDF? Run it through the managed platform and pull the technical report (**managed-pentesting-with-strix**).
+
+## Report honestly
+
+From `strix_runs/<run>/`, group `vulnerabilities/*.md` by category and state, per category: what was attempted, what was proven, and what could not be assessed (A09 always; A03/A04/A06/A08/A10 partially). Label the report with the edition used. Verify each PoC yourself before it goes in front of the user.
+
+A `0` exit code means nothing exploitable was proven **in what was analyzed** — check `run.json` status and cost against `--max-budget`; a budget-capped run is not a completed assessment.
+
+## Then fix and re-test
+
+Remediate with **fix-security-vulnerabilities-with-strix** and re-run to prove each exploit is closed. For ongoing coverage as the app changes, gate pull requests using **ci-security-scanning-with-strix**.

+# 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. For a run with no Docker and no LLM key, the same binary drives the managed platform: `strix cloud login`, then `strix cloud scans start ...` (details in **managed-pentesting-with-strix**). 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:

@@ -216,10 +232,32 @@ 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
+- 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. If your evidence proves more than the finding it matched (a working exploit where that one had only a static trace, a chain that raises the impact), revise that finding with update_vulnerability_report using the duplicate_of id — never re-file it.
+- REVISING A FINDING: use update_vulnerability_report (report id + the fields you want to replace + update_reason) when you learn something a finding already on file does not carry — you built the PoC after filing it, a chain raised its impact, further testing weakened it, or its counterevidence/remediation/code locations were wrong. Editing a finding needs no duplicate verdict, and it is always better than filing a second report for the same issue. Read the finding first with get_report, and pass only the fields that change.
 - 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`.
