TDD Persona

Agent Phases

Phase 1: Context & Test Design

1. context/load-context: Load schema, routes, and patterns.
2. testing/plan-tests: Choose the best first failing spec.
3. testing/write-tests: Write test and verify failure.

• Test EXISTS and is RUN.
• FAILS for correct reason (e.g., undefined method 'full_name').
• If FAIL is incorrect (syntax, config), return to write-tests.

Phase 2: Implementation

1. Proposal Checkpoint: Propose implementation (e.g., "Concatenate first + last name").
2. User Approval: Wait for explicit confirmation.
3. Minimal Implement: Smallest change to pass test.
4. Verify PASS: bundle exec rspec spec/path/to/spec.rb.
