Create Feature

Create Feature

Implement a new feature following a structured workflow from planning through PR creation.

Instructions

Follow this approach to create the feature: $ARGUMENTS

1. Understand Requirements

• Clarify the feature requirements and acceptance criteria. Ask the user if anything is ambiguous.
• Identify affected components and potential impact areas in the codebase.
• Review existing code patterns and conventions (CLAUDE.md, README.md, CONTRIBUTING.md).

2. Plan the Implementation

• Break the feature into smaller, ordered tasks.
• Design the API/interface contracts before writing implementation code.
• Plan database schema changes or migrations if needed.
• Identify external dependencies or libraries required.

3. Create a Feature Branch

• Create a branch: git checkout -b feature/$ARGUMENTS
• Install any new dependencies required.

4. Implement the Feature

• Start with core functionality and build incrementally.
• Follow the project's coding standards, patterns, and existing conventions.
• Implement proper error handling and input validation.
• Handle database migrations, API endpoints, and frontend changes as applicable.
• Keep security in mind: validate inputs, check authorization, avoid hardcoded secrets.

5. Write Tests

• Write unit tests for core business logic.
• Create integration tests for API endpoints or cross-module interactions.
• Test error scenarios, edge cases, and boundary conditions.
• Run the full test suite to ensure no regressions: use the project's test command.

6. Verify Quality

• Run linting and formatting tools (use the project's configured tools).
• Perform a self-review of all changes: git diff.
• Check for unused imports, dead code, or debugging artifacts left behind.
• Verify the feature works end-to-end against the acceptance criteria.

7. Add Documentation

• Add inline code documentation for complex logic.
• Update API documentation if endpoints were added or changed.
• Update README.md if setup steps or configuration changed.

8. Commit Changes

• Create atomic commits with descriptive messages.
• Follow conventional commit format if the project uses it.
• Separate refactoring commits from feature commits where possible.

9. Push and Create PR

• Push the feature branch: git push -u origin feature/$ARGUMENTS
• Create a PR with gh pr create including:
  • Clear description of what the feature does and why.
  • Summary of the implementation approach.
  • Testing instructions or screenshots if applicable.
  • Links to related issues or specifications.

10. Address Review Feedback

• Respond to code review comments with fixes or explanations.
• Push additional commits for review feedback (don't force-push during review).
• Re-run tests after making changes.
