Verify Build Works

Verify Build Works

When to run this skill

• After applying a fix from bug-triage-agent.
• After a rollback-safe operation.
• Before any commit larger than a single docs change.
• Before pushing to remote.
• Before opening a PR.
• Before tagging a release.

Verification ladder (run all that apply, in order)

Step 1 — Static checks (cheap, fast)

npm run typecheck
npm run lint

Stop and report at first failure. Don't continue if static layer is broken.

Step 2 — Build

npm run build

If build fails, hand off to bug-triage-agent.

Step 3 — Dev server starts

npm run dev

Confirm: process alive after 15s, HTTP 200 on http://localhost:<port>/, no fatal stderr.

Step 4 — Smoke test the golden path

For UI: load homepage + most critical authenticated page. For API: hit GET /health (or main endpoint) → 2xx.

npm run test:smoke   # if exists

Step 5 — Visual sanity (UI only)

• Open the affected page in a real browser.
• Confirm change is visible and not regressed.
• Confirm at least one adjacent feature didn't break.

Output format

🧪 verify-build-works

Step 1 — Static checks:    ✅ typecheck OK, lint OK
Step 2 — Build:            ✅ build succeeded in 14s
Step 3 — Dev server:       ✅ ready on :3000, GET / → 200
Step 4 — Smoke tests:      ⚠️  no test:smoke script — skipped
Step 5 — Visual sanity:    ✅ home renders, login renders

Verdict: SAFE TO COMMIT.

If any step fails:

🧪 verify-build-works — ❌ FAIL at Step 2 (build)

Erro principal: src/features/auth/sign-in.ts(23,7): TS2322 ...

Próximo passo: invoco o bug-triage-agent.

Tone for the vibe coder

Antes de avisar que terminou, eu sempre testo. Se algo está quebrado, eu falo agora — não na frente do primeiro usuário.

Do NOT

• Don't claim success without running the steps.
• Don't suppress errors with || true.
• Don't skip step 3 because "build passed".
• Don't run destructive commands (DB migrations, file deletions) as part of verification.
