What is the benefit of the 'one feature per session' rule?

This constraint prevents context exhaustion for the AI and ensures each feature is fully tested, verified, and committed before moving to the next task.

Does this skill support Git?

Yes, it includes an automated commit workflow that follows standard conventions and links every commit to a specific feature ID for better traceability.

Does it run tests automatically?

Yes, the agent follows a strict TDD cycle, meaning it writes and runs failing tests to verify the requirement before implementing the solution code.

How does the Coding Agent track progress?

It uses local state files like claude-progress.txt and feature_list.json to monitor completed tasks and pending features across multiple sessions.

Can I use this for existing projects?

Absolutely. The agent is designed to restore context from your existing Git log and project files, making it ideal for resuming development work.

Developer Tools

Automates incremental software development using a strict test-driven development (TDD) workflow and session-based state management.

TDD Coding Agent is a specialized workflow skill for Claude Code that enables systematic, feature-by-feature development. It manages the entire lifecycle of a coding task—from context restoration and environment checks to writing failing tests, implementing code, and committing work with structured messages. By enforcing a 'one feature per session' rule and a Red-Green-Refactor cycle, it ensures that your codebase remains in a mergeable, high-quality state while providing a clear audit trail of progress through local state tracking files.
