TDD Guardian is a Claude Code plugin that enforces strict test-driven development discipline with automated quality gates so developers can block commits until tests, coverage, and optional mutation checks pass.
About
TDD Guardian is a Claude Code marketplace plugin that enforces rigorous test-driven development through specialized subagents, automated quality gates, and hook-based commit blocking. It runs a six-step workflow covering planning, test design, implementation, coverage audit, mutation testing, and review. Developers reach for it when they want Claude to follow test-first discipline with measurable coverage thresholds rather than ad hoc testing. Installation is via the xiaolai marketplace with project initialization through /tdd-guardian:init.
- Six-agent TDD workflow from planning through review
- PreToolUse hooks block git commit/push without fresh gate passes
- Configurable coverage thresholds defaulting to 100%
- Optional mutation testing validates test robustness
- Auto-detects stack via /tdd-guardian:init

Who is it for?
Teams and developers who want hook-enforced TDD with coverage gates and a multi-agent test-first workflow in Claude Code.

FAQ
What commands does TDD Guardian provide?
/tdd-guardian:init auto-detects your stack and generates config; /tdd-guardian:workflow runs the full six-agent TDD pipeline.
How does it block bad commits?
PreToolUse and TaskCompleted hooks intercept git commit, push, and gh pr create until tests, coverage, and optional mutation gates pass within a freshness window.
Can I bypass the gates temporarily?
Yes, set the TDD_GUARD_BYPASS environment variable to skip all gates for a session.
