Use when implementing features or bug fixes test-first.
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
# Test-Driven Development Red then green. Consult this before and during the loop, not after. Read `CONTEXT.md` if it exists so test names match the domain glossary. Respect ADRs. ## Good test Tests verify behavior through public interfaces, not internals. A good test reads like a spec and survives refactors. ## Seams A seam is the public boundary you test at. Test only at pre-agreed seams. Write the seams down before the first test. Confirm with the human if they are in the session. No test at an unconfirmed seam. ## Anti-patterns - Implementation-coupled: mocks internals, private methods, or side channels. - Tautological: expected value recomputed the way the code does. - Horizontal slicing: all tests then all implementation. Use one test, one implementation, repeat. ## Loop - Red before green. - One seam, one test, one minimal implementation per cycle. - Refactoring is not part of this loop. It belongs to `/code-review`.

How to install
mdr add kripu77/software-factory/tdd@sha256:125633387f100bccThe line at the top of this page pins the label git:20260828.06ce8c3, 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.
