File contents

Preflight checks

Run the CI gates locally, in order, and report a concise pass/fail. Scope: $ARGUMENTS (empty = whole repo).

pnpm check — Biome lint + format. This is CI's gate (NOT pnpm lint). If it fails on formatting, run pnpm check:fix and re-run.
pnpm typecheck — tsc --noEmit across workspaces.
pnpm test — Vitest per workspace (API under @cloudflare/vitest-pool-workers).

If a workspace filter was given, prefer pnpm --filter <ws> test and pnpm --filter <ws> exec vitest run <path> for speed, but still run repo-wide pnpm check + pnpm typecheck (they're fast and cross-workspace).

Do not run pnpm smoke (production) or pnpm test:e2e (Playwright) here.

Report:

check:     PASS/FAIL
typecheck: PASS/FAIL
test:      PASS/FAIL  (<n passed, m failed>)

List each failure with file:line and a one-line cause. Stop and surface the first failing gate rather than pushing through.
