Version APIs so existing clients keep working while the contract evolves, with a real sunset process. Use when choosing a versioning scheme or planning a breaking API change.
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 The best version strategy is needing versions rarely: evolve additively, and when you must break, break loudly, once, with a long runway. ## Method 1. **Exhaust additive evolution first.** New optional fields, new endpoints, new enum values (documented as open sets) are not breaking. Removing, renaming, retyping, tightening validation, changing defaults or error codes are. Keep the taxonomy written down where reviewers see it (see api-change-management). 2. **Pick URL-path versioning unless you have a reason.** `/v1/orders` is visible in logs, testable in a browser, cacheable, and impossible to send by accident. Header/date-based versioning (Stripe-style pinning) is strictly better ergonomics at much higher implementation cost; choose it deliberately, not aspirationally. 3. **Version the whole surface, not per endpoint.** `/v1/orders` with `/v2/refunds` forces every client to carry a compatibility matrix. One version number, moved rarely. 4. **Keep old versions thin, not forked.** Implement vN-1 as a translation layer over the vN core (request/response adapters), or the old version …

How to install
mdr add amey-thakur/ai-skills/api-versioning@sha256:2170980b09d11152The line at the top of this page pins the label git:20260720.1dc980e, 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.
