Runs strict test-driven development one behaviour at a time. Picks the next smallest behaviour from the spec or task list, writes one failing test, makes the smallest change that passes it, then refactors with the tests green. A guard script records each step and refuses the usual shortcuts. It rejects a red step that fails for the wrong reason (syntax, import or compile error, missing function, no tests ran) and code written before any failing test. It also rejects a test that was edited…
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 Loop Build one behaviour at a time: a failing test, the least code that passes it, then a cleanup with the tests green. The guard script makes each step checkable, so "I wrote the test first" is a recorded fact rather than a claim. ## 0. Set up once ```bash python3 scripts/tdd_guard.py detect # suggests the test command from project files ``` Pick a command that runs once and exits (`npx vitest run`, not `vitest` in watch mode). Prefer one that runs the current test file or test, so cycles stay fast, and run the whole suite before each commit. The guard keeps its state in `.tdd/` at the project root and writes a `.tdd/.gitignore` so git ignores it. Add `.tdd/` to the project's `.gitignore` too if the user wants it listed there. Run one test: | Runner | Command | |---|---| | pytest | `python3 -m pytest -q tests/test_slug.py::test_lowercases` | | unittest | `python3 -m unittest tests.test_slug.SlugTest.test_lowercases` | | Vitest / Jest | `npx vitest run src/slug.test.ts -t "lowercases"` / `npx jest src/slug.test.ts -t "lowercases"` | | go test | `go test ./slug -run '^TestLowercases$'` | | cargo | `cargo test lowercases` | …

How to install
mdr add milad-ahmd/agent-skills/tdd-loop@sha256:e2f590d2e1399f0cThe line at the top of this page pins the label git:20261101.8a23731, 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.
