Gives your agent the ability to strictly follow the Red-Green-Refactor cycle to ensure every line of code is verified.
When implementing any new feature to ensure behavioral correctness
When fixing a bug by first reproducing it with a failing test
When refactoring existing code to maintain a safety net of automated tests
Write a minimal failing test that defines the expected new behavior
Verify the test fails for the correct reason (missing implementation)
Write the simplest possible production code to make the test pass
Clean up and refactor the code while ensuring all tests stay green
You
I want to add a feature that retries failed API calls three times.
Agent
I'll start by writing a failing test that expects a successful result after two simulated failures. After verifying it fails correctly, I'll implement the minimal retry logic in your production code. Finally, once the test passes, I'll refactor the code for better readability while ensuring the retry behavior remains fully verified.
Gives your agent the ability to execute subagent driven development tasks with a clear workflow.
Gives your agent the ability to guide the completion of development work by verifying tests and presenting structured options for merging, pushing, or cleaning up.
Gives your agent the ability to act as a senior QA Engineer, generating comprehensive test strategies and quality assurance plans based on international standards like ISTQB and ISO 25010.
Gives your agent the ability to generate comprehensive unit tests for any programming language using an automated multi-agent pipeline.
Gives your agent the ability to write failing tests first, creating a strict behavior contract for test-driven development.
