Produces an API version scheme (date-pinned header or URI), a breaking-vs-additive change policy, and a published deprecation/sunset timeline with translation shims. Use when removing or renaming a field or endpoint, tightening validation, cutting a "v2", binding a partner integration to a version, or planning how long an old version lives. Do NOT use when designing the resource shape, URLs, status codes, or pagination of a new endpoint - use REST API Design instead; this skill owns only the…

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 Strategist

Pick a version scheme, classify every change as breaking or additive, and ship a deprecation path that never silently breaks a live integration.

## Workflow

1. **Classify the change first.** Decide whether it is breaking or additive before choosing any mechanism.
   - Breaking: removing/renaming a field or endpoint; adding a required request field; tightening validation; changing a field's type or an enum's semantics; changing error codes or status codes clients branch on.
   - Additive (ship freely within the current version): adding optional request fields; adding response fields; adding endpoints; adding optional enum values clients are told to tolerate.
   - Mandate a tolerant-reader contract: clients MUST ignore unknown fields. Document this so additive changes stay non-breaking.
2. **Choose the scheme to match release cadence.**
   - Frequent, granular evolution → date-pinned versions: clients send a version header (a pinned release identifier), the account is bound to a default, and each release is a small documented set of breaking changes - ideally 1-5 per release, never dozens. Scales without parallel rewrites.

How to install

The exact contents, by fingerprint
mdr add skillmedev/skills/api-versioning-strategist@sha256:96d7dbe722cd9167

The line at the top of this page pins the label git:20261005.bea4ea5, 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.
