tdd-enforcement SKILL.md skillA
tdd-enforcement from a5c-ai/babysitter is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add a5c-ai/babysitter/tdd-enforcement@git:20260601.da7723aPins git:20260601.da7723a in mdr.lock. Pin the fingerprint instead.

Red-Green-Refactor TDD methodology with mandatory failing tests, minimal implementation, quality refactoring, and 80% coverage gating.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
- Write tests that define expected behavior - Tests MUST fail (exit code 1) - Use CI=true or --run flag, never watch mode - Apply timeout guards (60s) to prevent hanging - Record exit code as evidence ### 2. GREEN Phase - Minimal Implementation - Write the minimal code to make tests pass - Do NOT add features not covered by tests - Do NOT optimize prematurely - Tests MUST pass (exit code 0) - Record exit code as evidence ### 3. REFACTOR Phase - Quality Improvement - Apply SOLID principles and clean code patterns - Improve naming, reduce coupling - Remove duplication - Run tests after EACH refactoring step - Tests MUST remain passing (exit code 0) ### 4. Coverage Gate - Measure coverage: statements, branches, functions, lines - Minimum 80% overall coverage required - Iterate: write additional tests for gaps until threshold met - Maximum 3 convergence iterations ## Rules - Never skip the RED phase - Never accept GREEN without exit code 0 - Never use watch mode in CI - Always record evidence (exit codes, coverage numbers) - Enforce 80% coverage threshold ## When to Use - All code implementation tasks - Feature development - Bug fixes (write regression test first) …

How to install
mdr add a5c-ai/babysitter/tdd-enforcement@sha256:dd339e07f123dbd8The line at the top of this page pins the label git:20260601.da7723a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
