tdd-guardian-for-claude

Validate test strength with mutation testing and harden weak assertions. Covers Stryker (JS/TS), mutmut (Python), go-mutesting (Go), and cargo-mutants (Rust).

Initialize workspace TDD Guardian config and enable strict hooks for test/coverage enforcement.

Enforce coverage thresholds AND test quality — coverage without behavioral assertions is meaningless.

Produce findings-first code review with severity ordering, test-gap findings, and test-quality audit.

Build a comprehensive test matrix for changed behavior with explicit assertion strategy per case.

Global TDD governance policy. Enforces plan-first development, behavior-driven test quality, and strict completion gates.

Orchestrate strict TDD implementation across planner, implementer, test designer, coverage auditor, mutation auditor, and reviewer subagents.
