What I do

• Plan new features before implementation
• Write failing tests first (TDD approach)
• Implement features using dependency injection
• Follow Clean Architecture principles
• Validate implementation with tests

When to use me

Use this when adding new functionality, implementing new calculator methods, or creating new parsers/exporters. This follows the Plan-Then-Execute workflow.

Procedure

1. Plan the feature: State intent and approach
2. Write failing tests first (TDD)
3. Implement feature using dependency injection
4. Follow Clean Architecture layers from AGENTS.md
5. Run tests to verify implementation
6. Format and lint code
7. Create branch and commit conventionally
