| name | live-smoke |
| description | Run the live browser smoke test against the running app. Use when a feature needs verification in the real UI rather than in unit tests — checking that a schedule renders, a derived view follows an edit, or a shared URL round-trips. Also use when asked to run, drive, or screenshot the app. |
| argument-hint | Optional: a specific assertion or flow to check |
| compatibility | Requires playwright-core and a chromium build in the ms-playwright cache |
| user-invocable | true |

Live Smoke
scripts/smoke.mjs drives the running app in a real browser. It is the only
check that exercises what a user touches — the unit suite verifies the engine
and components in isolation and will happily agree with itself while the app is
broken.
Run it in a subagent
Dispatch this to a subagent, not the orchestrator. Locator failures come in
runs of four or five, each one a full round trip, and in an orchestrator at
300k context that is the most expensive verification in the feature. In a
subagent each iteration pays the subagent's small context and only the verdict
returns.
Model: Sonnet. Locator repair is not complicated work.
Procedure
- Start the dev server if nothing is serving
SMOKE_BASE:
pnpm dev in the background, wait for the port.
timeout 180 node scripts/smoke.mjs- Read the last line.
SMOKE PASS means every assertion held. Any other
ending names the step that failed.
- On failure, decide which of two things happened:
- The app is wrong. Report it. This is the outcome worth having.
- The locator is wrong. Fix it in
scripts/smoke.mjs and rerun.
Never fix a locator by writing a new scratch driver — that discards
every selector lesson already encoded here.
- Screenshots land in
scripts/smoke-shots/. Read one only when a failure
needs visual diagnosis, and prefer the viewport shot: SMOKE_FULLPAGE=1
produces images thousands of pixels tall that are expensive to pull into
context.

SMOKE_FULLPAGE | unset (viewport shots) |
Keeping it alive
The driver asserts against the current UI, so a feature that reshapes the UI
updates it in the same task that reshapes it — the same rule behavior changes
follow for their tests. P3 deletes the wizard and the layout toggle; its
wizard block goes then, and the assertions above it move to the new shell.
Do not let it rot into a file that is rewritten from scratch each feature. The
selectors in it are the record of five separate corrections against the real
DOM.
