About feature-implementation
feature-implementation is a skill that guides feature work from requirements analysis through implementation and test validation. It is intended for changes that need coordinated implementation, tests, and build or test checks.
Key features
- 01Clarify requirements and constraints
- 02Follow an implementation workflow
- 03Add or update tests
- 04Validate with builds and tests
Use cases
- 01Implementing a feature, component, service, or API
- 02Coordinating changes across UI, API, and tests
- 03Adding tests alongside implementation

Overview
Guide feature implementation with clear steps: analyze requirements, plan approach, implement safely, and validate with tests.
When to Use
- Implementing a feature, component, service, or API
- Coordinating multi-domain changes (UI + API + tests)
- Adding tests alongside implementation
Avoid when:
- The task is a trivial one-line change
- You only need a plan (use implementation-workflow)
Quick Reference
| Task | Load reference |
|---|---|
| Implementation workflow | skills/feature-implementation/references/implement.md |
Workflow
- Clarify requirements and constraints.
- Load the implementation reference.
- Implement changes with appropriate personas/tools.
- Add or update tests.
- Validate with builds/tests.
Output
- Implementation summary
- Validation results and remaining risks
Common Mistakes
- Implementing without tests or validation
- Skipping integration considerations
- Mixing planning and implementation without agreement
