name: feature-dev description: Guided feature development with codebase exploration, architecture design, and incremental implementation. Helps plan and build new features step by step.

Feature Development Skill

Guide feature development from requirements to implementation:

Process

1. Understand Requirements

• Clarify what the user wants to build
• Identify acceptance criteria and constraints

2. Explore Codebase

• Use grep, find, and read to understand existing patterns
• Identify files that need modification
• Find reusable utilities and abstractions

3. Design Approach

• Propose the implementation strategy
• List files to create or modify
• Consider edge cases and error handling

4. Implement Incrementally

• Make small, focused changes
• Test each change before moving on
• Use edit for modifications, write for new files

5. Verify

• Run existing tests with bash
• Check that the feature works as expected
• Review for code quality and security

Principles

• Reuse existing code and patterns when possible
• Keep changes minimal and focused
• Don't refactor unrelated code
• Ask for clarification when requirements are ambiguous
