About fullstack-software-engineer
A full-stack software engineering skill for delivering work across UI, APIs, and persistence. It supports vertical features, cross-client/server bug fixes, testing, and production debugging.
Key features
- 01Deliver features across UI and server
- 02Design API and database changes
- 03Implement auth, validation, and data flows
- 04Write unit, integration, and end-to-end tests
- 05Debug production issues and add regression tests
Use cases
- 01Build a vertical feature with UI, API, and storage
- 02Fix bugs spanning client and server
- 03Add authentication, pagination, or file uploads
- 04Test critical paths and prepare small changes

- Fix bugs spanning client and server
- Add auth, validation, pagination, or file upload flows
- Write or extend unit, integration, and critical-path e2e tests
When NOT to Use

Core Workflows
1. Vertical feature delivery
- Confirm acceptance criteria and edge cases (empty, error, permissions)
- Define API contract and UI states
- Implement server: validation, authz, persistence, migrations
- Implement client against typed contract
- Test: unit (logic), integration (API), e2e (happy path)
- Add logging/metrics on new paths; feature flag if risky
See references/feature_delivery.md for checklist.
2. API and database
| Concern | Default |
|---|---|
| Validation | Schema at boundary (Zod, Pydantic) |
| Auth | Session or JWT; check authz per resource |
| Queries | Avoid N+1; index for access patterns |
| Mutations | Transactions where needed; idempotency keys for payments-like flows |
| Errors | Stable codes; no internal details to clients |
See references/api_and_database.md for pagination and migrations.
3. Frontend integration
- Match loading/error/empty states to design
- Prefer server fetch for read-heavy pages when using Next.js App Router
- Client components only for interactivity
- Accessible forms (labels, focus, keyboard)
See references/frontend_integration.md for forms and caching.
4. Testing and PR hygiene
- Lint and typecheck clean
- Tests cover changed behavior, not only happy path
- No secrets in repo; env via configuration
- Small PRs; describe rollout and rollback
See references/testing_debugging.md for test pyramid.
5. Production debugging
- Reproduce with correlation ID or request ID
- Check deploys, flags, and recent config changes
- Trace: logs → metrics → DB slow queries
- Fix with regression test; hotfix or rollback per severity
See references/testing_debugging.md for common failures.
