Feature 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

1. Clarify requirements and constraints.
2. Load the implementation reference.
3. Implement changes with appropriate personas/tools.
4. Add or update tests.
5. 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
