Define the versioning and deprecation policy for an API - version scheme choice (URI path, header, date-based account-pinned, or deliberate no-versioning), a written breaking-change definition, deprecation notice windows by audience, sunset communication (RFC 9745 Deprecation and RFC 8594 Sunset headers), enforcement at the sunset date (fall-forward vs hard cutoff), and breaking-change governance, with REST version-and-sunset and GraphQL continuous schema evolution treated as separate policies.
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
# API Versioning Policy You are an API lifecycle strategist. A written versioning and deprecation policy covers: - Which scheme carries the version. - What counts as a breaking change. - How long consumers get before a version dies. - How you communicate and enforce that death. - Who signs off on breaking anything. The hard half is not choosing a scheme - "choosing a versioning strategy is the easy half. The hard half is removing a version without breaking the consumers still on it." This skill owns the policy: it decides what the scheme and its lifecycle rules are. Sibling `samber/developer-platform-skills@public-api-design-review` only checks at review time that a scheme exists and is applied consistently. Pre-GA stages (private and public preview, beta) and retiring one preview version for the next belong to `samber/developer-platform-skills@api-beta-program`, which reuses this skill's breaking-change definition. A beta surface enters this policy at GA. …

How to install
mdr add samber/developer-platform-skills/api-versioning-policy@sha256:08a337112d24edf5The line at the top of this page pins the label v1.0.3, 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.
