Use when building features, writing code, or fixing bugs. context: fork agent: full-stack-dev --- # Implementing Features Delegates code implementation to the full-stack-dev subagent. ## When to Use - Building new features - Implementing technical specifications - Setting up project infrastructure - Fixing bugs - Writing tests ## Expected Outputs - Source code in `src/` (or framework-appropriate location) - Tests alongside source or in `tests/` - Updated documentation in `docs/technical/` ## Quality Criteria Code must meet these gates: - [ ] All tests pass - [ ] Linter passes with no errors - [ ] Build succeeds - [ ] No security vulnerabilities - [ ] Documentation updated if API changed
