Guide for implementing features using TDD workflow when explicitly requested. TDD follows red-green-refactor cycle: write failing tests first, implement minimal code to pass, then refactor while keeping tests green.

1. Write Failing Test (Red Phase): Write test describing desired behavior, test should fail initially, focus on behavior not implementation, follow project testing conventions (see @.cursor/rules/base/testing.mdc), use real APIs - no mocks for core functionality
2. Implement Minimal Code (Green Phase): Write simplest code that makes test pass, don't worry about code quality yet, verify test passes, avoid over-engineering
3. Refactor (Refactor Phase): Improve code quality while keeping tests green, extract common patterns/improve naming/reduce duplication, ensure all tests still pass, follow project coding standards/linting rules
4. Repeat Cycle: Continue red-green-refactor for each feature increment, build up functionality incrementally, each cycle should be small and focused
