Improve code correctness using Momentic specs in the feature development process.
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
# Momentic spec-driven development Write the expected product behavior as Momentic tests before implementing it. The tests define the contract; do not make the tests fit the implementation. ## Non-negotiable sequence 1. Read repository guidance, `momentic.config.yaml`, and nearby tests and modules. 2. Identify and report the exact Momentic tests expected to be affected. 3. Create or modify those tests before changing product code. 4. Review the test diff as a product specification. 5. Only then implement the product change. 6. Use fast code-level checks while implementing; do not run Momentic after every edit or commit. 7. At a durable end-to-end checkpoint, prepare the required test state, enable the affected tests that should now pass, and ask whether to run the smallest affected set. Do not begin product implementation until the intended test specifications are on disk. If the user changes the requirement, update the spec first again. ## Choose the affected tests - If the user names specific existing tests, start with those tests and keep the work focused on them. Expand the set only when repository evidence shows …

How to install
mdr add momentic-ai/skills/momentic-spec@sha256:8501575b40e7fbffThe line at the top of this page pins the label git:20260927.6c926db, 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.
