Harden a REQUIREMENTS or PLAN document against its ticket and the code before the next phase picks it up.
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
# Harden artifact Make a `.REQUIREMENTS.md` or `.PLAN.md` — the **artifact** — safe to hand to the next phase: every deviation from its ticket deliberate, explained and correct; every claim true; nothing blocking the session that picks it up. A fresh-context reviewer hunts, the session challenges each finding, and only what survives changes the artifact — which **must never end worse than it started**. A session that wrote the artifact cannot judge findings on it: say so and propose a fresh session before continuing. ## Resolve the sources - **Artifact** — the file the invocation names; ambiguous or neither kind → ask. A plan — the artifact or one of the same base — with a ticked task is already being built, past where hardening belongs → say so and ask before going on. - **Ticket** — the document the artifact was refined from, found by file name: the artifact's suffix replaced by `.TICKET` (`FOO.PLAN.md` → `FOO.TICKET.md`), or, when the stem names another source, that file (`FOO.PR-REVIEW.REQUIREMENTS.md` → `FOO.PR-REVIEW.md`). A `.TICKET.md` is taken at its latest version: with `<base>` the artifact's base stripped of any trailing `-vN`, …

How to install
mdr add eai-org/agent-toolkit/harden-artifact@sha256:d99a1a475b304dd5The line at the top of this page pins the label v0.6, 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.
