Test Driven Agent Protocol

1. The Red-Green-Refactor Cycle

1. Red: Write a test that fails (demonstrating the bug or missing feature).
   • Agent Note: If fixing a bug, YOU MUST reproduce it with a test first.
2. Green: Write the minimal code to pass the test.
3. Refactor: Clean up the code while ensuring tests still pass.

2. Test Coverage Requirements

• Happy Path: The "standard" usage case.
• Sad Path: Error states, network failures, invalid inputs.
• Edge Cases: Empty lists, max values, concurrent actions.

3. Self-Healing Mandate

If a test fails after your changes:

• DO NOT delete the test.
• DO NOT comment out the assertion.
• DO NOT change the test expectation to match the buggy result (unless the spec changed).
• DO: Fix the implementation logic until the test passes.

4. Integration vs Unit

• Unit: Mock external dependencies (Supabase, API). Fast, isolated.
• Integration: Test the hook or service with realistic (mocked) data flows.

5. Verification Checklist

• Did I write a test case for this requirement?
• Did I run npm test <filename>?
• Did I check specifically for regression in related headers/components?
