This is the most faithful option, because it tests the same artefact. | `dockerfile`, `docker-context`, `docker-build-args`, `env` | +| `command` | Install, build and start on the runner. | `setup`, `package-manager`, `install`, `build`, `start` | +| `static` | The build output is plain files (CRA, Vite, webpack, exported sites). | `build`, `static-dir`, `spa` | + +Two inputs apply across modes: + +- **`build-image`** (`command` and `static` modes): runs the install and build + inside an old toolchain image such as `node:14-bullseye`. This is for legacy + apps whose toolchain no longer builds on current Node. The browser checks + still run on the runner. +- **`postgres: "17"`**: starts Postgres and exports `DATABASE_URL`. Use + `migrate` to run migrations and seed data before start. + +In `docker` mode, `env` reaches the running container only. Values the image +needs at build time, such as `NEXT_PUBLIC_*`, go in `docker-build-args`. + +Everything in `env` must be a CI-only dummy value. The gate never needs real +credentials, and an app that can't boot without them should get a fake or +dry-run mode. + +### Tuning + +| Input | Use it to | +|---|---| +| `routes` | Visit pages that nothing links to. | +| `exclude` | Skip paths with side effects. | +| `quarantine` | Show a known problem without blocking on it (see below). | +| `ignore` | Tolerate a known, accepted console message or URL. Each entry hides a whole class of error, so keep the list short and comment why. | +| `http-user`, `http-password` | Get past a staging basic-auth gate. Use dummy CI values. | +| `browser` | Choose `chromium` (the default), `chrome`, `firefox` or `webkit`. | +| `headed` | Set to `true` to run the browser with a visible window on a virtual display. | + +### When the AI explorer runs + +With `explore: auto`, the default, the explorer runs when any of these is +true: + +- the run is a schedule or a manual dispatch; +- the PR has the `major-upgrade` label (the Renovate preset adds it) or the + `ai-explore` label; +- the PR title names a framework or a major update. + +The `explore-match` input holds that title pattern. A typical match is +"Update dependency next to v16.4". + +The explorer uses the Gemini API free tier, with the `gemini-flash-latest` +model by default. It sends at most 8 requests a minute and makes 30 steps per +run. Get a key from Google AI Studio and store it as the `GEMINI_API_KEY` +secret. Without the secret the explorer reports itself skipped and the crawl +still gates. + +How Google may use what the explorer sends (page text and screenshots) is +set by the [Gemini API Additional Terms of Service](https://ai.google.dev/gemini-api/terms), +section "How Google Uses Your Data". At the time of writing they apply the +paid-service terms (prompts and responses not used to improve Google's +products) to all usage from the UK, EEA and Switzerland, including free +quota; elsewhere, free-tier content may be used to improve Google's products. +Check the current terms before pointing the explorer at an app whose content +must not leave your control, and use a paid-tier key if in doubt. + +### Signed in + +Most of an app usually sits behind a login. Give the gate a test account and +the crawl runs twice, signed out and signed in; the explorer starts signed in. + +| Input | Use it to | +|---|---| +| `login-path` | The sign-in page, e.g. `/login`. Turns the signed-in crawl on. | +| `login-username`, `login-password` | The test account. CI-only dummies, never a real account: seed it with `migrate`, or let the gate register it. | +| `signup-path` | Register the account through the app's own sign-up page first, for apps without seed data. | +| `login-check` | A path only signed-in users can open. The gate opens it after signing in and fails if it is sent back to the sign-in page. Without it, the sign-in form must be gone after submitting. | +| `login-script` | A module in the repo for sign-ins a plain form can't do (multi-step, OAuth stubs). Its default export receives `{ page, context, base, username, password }`. | + +A sign-in that stops working is a blocking `login-failed` finding: if a +dependency update breaks sign-in, that is what the gate is for. + +The gate signs in before the signed-out crawl starts, because that crawl +fills sign-up forms with its own dummy address (`ci@example.com`) and could +otherwise claim the test account's address first. Without `login-check`, +any password field left on the sign-in page after submitting means the +sign-in failed (some sign-in forms have a second masked field, such as a +security code); elsewhere, only a form with a single password field counts as +"still on the sign-in page", so a `login-check` page may contain a +change-password form. + +The signed-in crawl skips public pages that already rendered fine for a +visitor, never opens sign-out links, and never submits a form with a password +field (that would change the test account or sign in as someone else). + +### Recorded flows + +When the explorer completes a sequence of actions without a runtime error, it +records it as a flow: a start page and up to 10 steps, such as "open +/dashboard, click Add item, click All items". On scheduled and manual runs of +the default branch, `runtime-gate-flows.yml` saves new flows to +`.github/runtime-gate-flows.json` on the branch `runtime-gate/flows` and opens +one PR for a person to review. Recorded flows become part of the gate only +once someone has looked at them and merged them. + +The crawl then replays every saved flow on every PR, exactly as recorded and +with no model calls. A flow that can no longer be done (a button that is gone, +a dialog that no longer opens) is a `flow-broken` finding. With +`flows-strict: auto`, the default, that blocks dependency-update PRs (from +Renovate or Dependabot, where the interface should not change) and is a +warning on other PRs (where the change may be intended and the flow just +needs re-recording or deleting). Runtime errors during a replay always count. + +```yaml + flows: + needs: runtime + if: ${{ !cancelled() && (github.event_name == 'schedule' || github.event_name == 'workflow_dispatch') }} + uses: rishitank/.github/.github/workflows/runtime-gate-flows.yml@ + permissions: + contents: write # push the runtime-gate/flows branch + pull-requests: write # open or update its PR + actions: write # start CI on that branch + with: + ci-workflows: ci.yml # workflows to start on the flows PR (need workflow_dispatch) +``` + +PRs opened by GitHub Actions don't start `pull_request` workflows, so the +workflows named in `ci-workflows` are started on the branch instead. If the +repository doesn't allow GitHub Actions to create pull requests, the branch is +still pushed and the run prints a link to open the PR by hand. + +### Flaky findings and quarantine + +A page with a blocking finding is opened once more in a clean browser. A +finding that doesn't happen again is reported as **flaky**: still shown in +the PR comment, but not blocking. This is deliberately conservative: if the +retry shows any blocking problem of the same kind on that page, nothing is +downgraded. Turn it off with `retry: false`. + +`quarantine` takes regexes for known problems you have decided to live with +for now. They are matched against `kind: message @ /path`, stay visible in +the comment, and don't block. Put an issue link in a YAML comment next to +each entry, and remove it when the issue is fixed. + +### Coverage + +Each run reports how much of the app the crawl reached: + +- routes visited out of routes discovered, and the ones it didn't reach; +- controls operated out of distinct controls found; +- forms submitted out of forms found; +- the share of the app's own JavaScript that actually ran (V8 block coverage, + Chromium only). + +The default branch's numbers travel with the visual baseline, so a PR shows +the change, for example "routes −2, JS −6.3 pts". A drop means the crawl +reached less of the app than before: a route that now redirects, a menu that +no longer opens, a code-split chunk that no longer loads. It is advisory. + +### Giving the explorer hints + +Add `.github/runtime-gate.md` to the app repo, covering: + +- what the app is for; +- the flows that matter most; +- any test login seeded by `migrate`. + +The explorer reads this file as operator instructions. + +## Safety + +- **Page content is untrusted.** The explorer prompt says so, and the + explorer cannot leave the app's origin. Its only tools are browser actions: + there is no shell and no file access. +- **Pages are screened for prompt injection before the model sees them.** + Every observation goes through pattern checks (instructions aimed at AI + agents, chat-template tokens, invisible Unicode) and, with + `explore-guard: model`, a separate small classifier model + (`gemini-flash-lite-latest`, its own free-tier budget). Long pages are + checked in overlapping chunks, and one flagged chunk withholds the whole + page. A flagged page is replaced by a placeholder with no screenshot, and + the PR comment lists it. This follows the BrowseSafe pattern + (arXiv 2511.20597). Text drawn only inside images is not screened; that is + why the validation below exists. +- **Every action is validated before it runs.** Roles and keys come from + allowlists, navigation must stay on the app, typed text is capped and may + not contain links to other sites or encoded payloads, and a signed-in + explorer can't sign itself out. Recorded flows are validated the same way + when they are replayed. +- **The Gemini key is scoped to one step.** It goes only to the explorer + step, never to the install, build, migrate or start commands. In `command` + and `static` modes the app (and anything its install left running) is + still running as the same user on the same runner while the explorer + runs, so it could read the key from the explorer's process.
