 Instead of a metered API key, you can run Strix on your ChatGPT Plus/Pro subscription:

-
+strix auth login chatgpt             # sign in with your ChatGPT account
 export STRIX_LLM="chatgpt/gpt-5.4"   # chatgpt/<model> runs on the subscription

-strix auth logout             # forget the sign-in
+strix auth status                    # show the active sign-in, or logout to forget it
 ```
 
 #### Use the managed platform: `strix cloud`
 
-The `strix cloud` commands drive the managed platform ([app.strix.ai](https://app.strix.ai)) from the terminal. Sign in once with the device flow. The sign-in creates your account and workspace on first use and stores a personal API token in `~/.strix/platform-auth.json`:
+Run scans on [app.strix.ai](https://app.strix.ai) from the terminal, without Docker or an LLM key:
 
 ```bash
-strix cloud login                         # browser approval, then workspace + scope profile
-strix cloud login --workspace "My Team"   # select a workspace by name or ID
-strix cloud whoami                        # fast local account/workspace status
-strix cloud session                       # verify remote session + consent ceiling
-strix cloud logout                        # revoke remotely, then remove locally
-```
-
-The default **Recommended** scope preset supports normal scan work, local source uploads,
-workspace switching, and user-approved credit top-ups. It excludes credential creation;
-request `tokens:write` explicitly (or choose Full) when needed. For strict least privilege, pass an explicit list such as
-`--scopes scans:read scans:write uploads:write billing:read`. Named automation
-profiles are also available with `--scope-profile minimal|recommended|full`.
-
-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 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 scans start --source . --dry-run --show-files --json  # review + capture source.archive_sha256
-SOURCE_SHA256="<reviewed source.archive_sha256>"
-strix cloud scans start --source . --approve-sha256 "$SOURCE_SHA256" --wait
 strix cloud vulns list --severity critical
-strix cloud credits                           # credit balance
-strix cloud billing topup --credits 20 --yes  # explicitly approve agent payment after HTTP 402
 ```
 
-Workspaces and account setup also work from the terminal:
+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.
 
-```bash
-strix cloud workspaces list                   # numbered list; `workspace` is also accepted
-strix cloud workspaces create --name "My Team" # admin + organizations:write
-strix cloud workspaces use 2                  # switch by list number, exact name, or ID
-strix cloud session scopes                    # granted scopes + login ceiling
-strix cloud session scopes set minimal        # narrow without another browser sign-in
-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.
-
-The commands work for humans and agents: terminal output favors names, branches, lifecycle states, and numbered selectors, while redirected output (or `--json`) preserves complete machine-readable records and IDs. 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 distinguish API keys from named CLI device sessions. Binary downloads are the exception: intentionally redirect their raw bytes, 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. `--token` and `STRIX_API_TOKEN` are stateless per-command overrides and never replace the stored sign-in; pair a CLI-session override with `--workspace-id` or `STRIX_WORKSPACE_ID`.
-
-A browser sign-in creates one reusable credential per CLI installation. Logging in again on the
-same installation replaces its secret instead of accumulating keys. Workspace switches keep that
-credential and expiry, preserve the server-side scope preference, cap access by the target role,
-and can never exceed the login consent ceiling. Each process pins its starting workspace, so a
-concurrent switch fails safely instead of sending a stale command to another organization.
-`strix cloud logout` revokes the server session before deleting the local token; use
-`--local-only` only when you deliberately cannot reach the server.
-
-Write commands take request fields as flags, and 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
-```
-
-For an agent or CI local-source scan, run `--dry-run --show-files --json`, review the manifest,
-and capture `source.archive_sha256`. Rerun with the same `--source`, every `--exclude`, and any
-`--include-*` selection flags, replacing `--dry-run` with `--approve-sha256 HASH`; Strix
-rebuilds the archive and refuses to upload it if the digest changed. `--yes` instead approves
-only the snapshot built in that one invocation. It is suitable for a deliberate human or
-one-shot approval, not as a digest-bound two-step agent/CI handoff.
-
-The safe default honors `.gitignore` and `.strixignore` and excludes hidden paths, secret-like
-files, VCS metadata, dependencies/build output, symlinks, and nested archives. Opt in
-separately with `--include-hidden`, `--include-sensitive`, or `--include-archives`. The client
-caps a bundle at 20,000 files, 25 MiB per file, 250 MiB expanded, and 50 MiB compressed, and
-the service independently validates the archive. Source alone infers a code review; adding a
-domain infers a live test. You can always pass `--engagement-type` explicitly.
-
-Strix removes the temporary local archive after every invocation. It deletes a staged remote
-upload after a definitive scan rejection. If a network error, `5xx` response, malformed
-success response, or interruption makes the launch outcome ambiguous, it retains the upload and reports its `upload_id` with
-`launch_outcome_unknown: true`; if automatic deletion cannot be confirmed, it reports the ID
-with `cleanup_unknown: true`. Check `strix cloud scans list` before retrying. If no scan is
-linked to the retained upload, delete it with `strix cloud uploads delete UPLOAD_ID`.
-
-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. Plan blocks exit `4`; an
-insufficient credit wallet exits `5` without creating or charging a scan.
-
-Enable native tab completion once per shell session:
-
-```bash
-source <(strix completions zsh)       # use bash instead of zsh when appropriate
-strix completions fish | source
-```
+See the [cloud CLI documentation](https://docs.strix.ai/cloud/cli) for scopes, workspaces, billing, and source-upload options.

+title: "Cloud CLI"
+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:
+
+```bash
+source <(strix completions zsh)       # use bash instead of zsh when appropriate
+strix completions fish | source
+```

+description: "Configure Strix with models via Vercel AI Gateway"
+---
+
+[Vercel AI Gateway](https://vercel.com/docs/ai-gateway) provides an OpenAI-compatible API for models from multiple providers.
+
+## Setup
+
+Create an [AI Gateway API key](https://vercel.com/docs/ai-gateway/authentication-and-byok), then configure Strix:
+
+```bash
+export STRIX_LLM="openai/anthropic/claude-opus-5"
+export LLM_API_KEY="your-ai-gateway-api-key"
+export LLM_API_BASE="https://ai-gateway.vercel.sh/v1"
+```
+
+The first `openai/` segment tells Strix to use its OpenAI-compatible client. The remaining value is the [AI Gateway model ID](https://vercel.com/docs/ai-gateway/models-and-providers).
+
+## Available Models
+
+Use any language model returned by the AI Gateway models endpoint:
+
+```text
+https://ai-gateway.vercel.sh/v1/models
+```
+
+Prefix its model ID with `openai/` when setting `STRIX_LLM`. For example, the Gateway model ID `anthropic/claude-opus-5` becomes `openai/anthropic/claude-opus-5` in Strix.
+
+## Get API Key
+
+1. Open the [AI Gateway API key settings](https://vercel.com/docs/ai-gateway/authentication-and-byok)
+2. Create an API key
+3. Set the key as `LLM_API_KEY`
+
+## Benefits
+
+- Access models from multiple providers through one endpoint
+- Track Gateway usage and cost in Vercel

+title: "Local Web Viewer"
+description: "Browse a run in a local dashboard with strix view"
+---
+
+Every scan writes its results to disk as it runs. `strix view` serves those files in a local dashboard, for a live run or a finished one.
+
+```bash
+strix view                                    # the most recent run
+strix view my-run-name                        # a specific run under ./strix_runs
+strix view --host 0.0.0.0 --port 8080 --no-open
+```
+
+The UI ships prebuilt with Strix, so there is no extra install and no JavaScript build step. The dashboard reads the run files straight off disk. Nothing leaves your machine, and you do not need a cloud account.
+
+## Options
+
+<ParamField path="run" type="string">
+  Run name under `./strix_runs`. Defaults to the most recent run.
+</ParamField>
+
+<ParamField path="--host" type="string" default="127.0.0.1">
+  Host to bind to. Use `0.0.0.0` to reach the viewer from other machines.
+</ParamField>
+
+<ParamField path="--port" type="number" default="0">
+  Port to serve on. The default selects an available ephemeral port.
+</ParamField>
+
+<ParamField path="--no-open" type="boolean">
+  Do not open the browser automatically.
+</ParamField>
+
+## What Is In The Dashboard
+
+- **Overview** — run status, target, and a severity breakdown of everything found so far.
+- **Vulnerabilities** — each validated finding with its severity, details, and reproduction steps.
+- **Agent graph** — a live map of the multi-agent team, and what each agent is doing.
+- **Steering** — send instructions to a live scan to redirect the agents during the run. Steering works only in the dashboard the running scan opens. A standalone `strix view` has no live scan to steer.
+- **History** — browse past runs on this machine and move between them. Verify your email address in the dashboard to unlock the other runs.
+- **Reports** — generate a shareable report and send it by email. Verify your email address first.
+
+## Sharing The Link
+
+<Warning>
+  The token in the printed URL grants access to the run data, and to the steering of a live scan. Share it only with trusted users.
+</Warning>
+
+To reach the viewer from another machine, start it with `--host 0.0.0.0` and replace `0.0.0.0` in the printed URL with a reachable IP address or hostname. Restrict the port with your firewall. A request without the token-derived session cannot read run data.

 - In CI/headless runs Strix automatically scopes to the PR's changed files (`--scope-mode auto`). If diff resolution fails, keep `fetch-depth: 0` or set `--diff-base` to the PR's actual base branch — use `origin/${{ github.base_ref }}` in GitHub Actions rather than a hard-coded `origin/main`, since repos use different default branches.

+- Exit codes: `0` pass, `2` vulnerabilities found (fails the job), `1` setup error. Add `--fail-on high` to fail only on high/critical findings; lower ones are still reported, so a passing job is not a finding-free report.
 - The runner needs Docker (default GitHub-hosted Ubuntu runners have it).
 - **Size the budget so the scan completes — do not let it fail open.** A `0` exit means "no validated vulnerabilities in what was analyzed"; if `--max-budget` is hit before the diff is fully covered, the scan wraps up early and can still exit `0`. The "Fail unless the scan completed" step above narrows the gap: `strix_runs/<run>/run.json` is `"stopped"` when the scan was cut off at the hard budget limit without a final report. It is not a complete guard — the agents get graduated wrap-up warnings before that limit, and a run that wraps up on a warning still calls `finish_scan` and records `"completed"` with partial coverage. So keep that step in any pipeline that gates merges **and** give the scan real headroom (compare `run.json`'s `llm_usage.cost` against `--max-budget`; if it ran right up to the cap, raise it). For a `quick` diff-scoped PR scan `--max-budget 10` is usually ample, raise it for large diffs.

 THOROUGH VALIDATION MANDATE:
@@ -240,7 +208,9 @@ VALIDATION REQUIREMENTS:
 - 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. 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.
+- HTTP EVIDENCE: a finding you validated through the proxy is not fully filed until `http_exchange_ids` carries the proxy request ids of the exchanges that prove it — the request that triggers the vulnerability plus the baseline/control request it differs from (an unauthenticated success next to the authenticated one, the payload response next to the benign one). Copy the ids exactly as `list_requests`/`view_request` show them, never invent or guess one, and never omit the field to bypass validation. Leave it out only when there is no captured HTTP exchange at all (static-only code findings, dependency CVEs). If you filed before the proving exchanges existed, attach them afterwards with update_vulnerability_report. Without the ids, the finding ships as prose nobody can replay.
 - 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.
+- WITHDRAWING A FINDING: when re-testing proves a finding you filed is not a vulnerability at all — the exploit only worked because of your own test setup (a mixed-up session, a self-inflicted state change, a misread response), the behaviour is intended, or the control is in fact enforced — delete it with delete_vulnerability_report (report id + delete_reason). Never leave a disproved finding on file as a zero-CVSS, "retracted", or "false positive" report, and never rewrite its text into a note saying it was wrong: a report that exists is read as a finding. Delete is for a finding that does not exist; a finding that is real but weaker than filed is revised, not deleted.
 - 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.
