Strict RED->GREEN->REFACTOR test-driven development with enforcement. Never write production code before a failing test. Atomic commits per TDD cycle.
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
## TDD Cycle ### RED Phase 1. Write a test that captures exactly one acceptance criterion 2. Run the test -- it MUST fail 3. Verify it fails for the RIGHT reason (not a syntax error) 4. Commit: `test: add failing test for [criterion]` ### GREEN Phase 1. Write the MINIMUM code to make the test pass 2. Run the test -- it MUST pass 3. Verify only the target test turned green (no side effects) 4. Commit: `feat: implement [criterion]` ### REFACTOR Phase 1. Clean up code while keeping ALL tests green 2. Remove duplication, improve naming, extract methods 3. Run full test suite -- ALL tests MUST pass 4. Commit: `refactor: clean up [area]` ## Compliance Scoring | Score | Meaning | |-------|---------| | 90-100 | Exemplary TDD: all cycles followed correctly | | 70-89 | Good TDD: minor deviations | | 50-69 | Partial TDD: some implementation before tests | | 0-49 | TDD violation: significant implementation without tests | ## Verification Methods 1. **Git History Analysis**: Test files must appear in commits before implementation files 2. **Coverage Analysis**: New code must have >90% test coverage 3. **Commit Message Convention**: RED/GREEN/REFACTOR phases identifiable in messages

How to install
mdr add a5c-ai/babysitter/strict-tdd@sha256:2231f52238ed269cThe line at the top of this page pins the label v1.0.0, 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.
