Never claim completion without evidence. Verify before asserting.
"Trust, but verify" - Don't assume code works; prove it works.
Run the Code
Check the Output
Test Edge Cases
Verify in Context
Before marking complete:
- [ ] Code compiles/transpiles without errors
- [ ] Tests pass (existing + new)
- [ ] Manual verification performed
- [ ] Edge cases checked
- [ ] Error handling works
- [ ] Integration verified
# Type check
npx tsc --noEmit
# Run tests
npm test
# Build verification
npm run build
When claiming completion, provide evidence:
## Verification Evidence
**What was verified:**
- Feature X works correctly
**How it was verified:**
- Ran `npm test` - 45/45 tests passing
- Manually tested in browser at /feature-x
- Checked error handling with invalid input
**Results observed:**
- Success case: Shows expected output
- Error case: Displays user-friendly message
- Edge case: Handles empty state gracefully
| Level | Meaning | Evidence Required |
|---|---|---|
| Certain | Verified with tests + manual | Tests + screenshots/logs |
| High | Verified with tests | Passing test output |
| Medium | Manually verified | Description of manual test |
| Low | Code review only | Should verify more |
| None | Assumption only | Must verify before claiming |

Claim completion with evidence
WHEN to auto-invoke: Creating API routes, building endpoints, adding route.ts files, implementing REST/GraphQL APIs, adding authentication to APIs, rate limiting, API validation with Zod, handling HTTP methods (GET/POST/PUT/DELETE). WHEN NOT to invoke: Pure frontend work, styling, React components without API calls, documentation-only tasks, database migrations without API changes.
WHEN to auto-invoke: Code review requests, refactoring code, cleaning up code, performance optimization, security audits, linting issues, reducing technical debt. WHEN NOT to invoke: Building new features (use domain-specific skills), initial implementation, documentation-only work.
WHEN to auto-invoke: Database schema design, creating migrations, writing SQL queries, query optimization, Supabase operations, Prisma/Drizzle schema changes, PostgreSQL tasks, RLS policies, indexes. WHEN NOT to invoke: Pure frontend work, API logic without database, styling, React components, deployment tasks.
WHEN to auto-invoke: Creating CI/CD pipelines, GitHub Actions workflows, Docker/containerization, Vercel/Netlify deployment, infrastructure as code, environment variables, deployment configurations. WHEN NOT to invoke: Application code changes, UI development, database schema design, testing application logic.
WHEN to auto-invoke: Creating UI components, building React/Vue/Svelte components, Next.js pages, styling with Tailwind/CSS, state management setup, form handling, accessibility improvements, client-side interactivity. WHEN NOT to invoke: API-only work, database operations, backend logic, DevOps/deployment, pure testing without UI.
Use this skill for isolated branch workflows and parallel development. Activates when working on features that need isolation, switching contexts, or managing multiple branches.
