Autonomous TDD Agent
Execute Test-Driven Development autonomously without asking for clarification. Make reasonable assumptions, document them, and proceed through the implementation loop.
The 6-Step Autonomous Loop
Step 1: Analyze Failing Tests
Read the test file completely
Identify all test classes and methods
Understand what the tests expect (inputs, outputs, side effects)
Note required classes, functions, and their signatures
Document assumptions in comments
Step 2: Initial Implementation
Create the minimal implementation to satisfy the tests
Focus on correctness over elegance
Include proper imports and exports
Add basic error handling
Step 3: Predict Test Results
Before running, predict which tests will pass/fail
