Audit or harden an existing application's release readiness, including deploy prerequisites, minimal release gates, rollback, production-shaped smoke checks, and post-deploy verification. Use only when the user explicitly asks for a release-readiness review, deploy or release gates, rollback rehearsal, production verification, or hardening of a deployment path. Do not trigger merely because work will eventually be merged, shipped, deployed, or touches CI/CD.
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
# Release Readiness Hardening Use this skill to answer: can this ship safely, and what is the smallest sufficient proof? Treat every gate, identity, queue, receipt, and manual step as operational cost. ## Counterweight: simplify before adding - Start from current callers, stored data, provider facts, and failure history. Do not preserve machinery merely because it exists. - Inventory existing controls before proposing new ones. Delete, combine, or narrow controls that duplicate the same authority or fact. - Add a gate only for a concrete material failure mode not already covered. Record why a cheaper existing signal is insufficient. - When one trusted system builds, deploys, and observes production end to end, do not invent signatures, admission ceremonies, or proof handoffs between its internal stages. - Prefer authoritative external facts—exact source, immutable provider version, traffic, health, and rollback target—over duplicated internal evidence. - Do not create bookkeeping PRs, proof PRs, smoke commits, or known-impossible release attempts solely to exercise release machinery. …

How to install
mdr add swyxio/skills/release-readiness-hardening@sha256:b4e3c19c82278d8cThe line at the top of this page pins the label git:20260809.02acf6b, 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.
