Retire API surface with sunset headers, usage tracking, migration guides, and enforced timelines. Use when removing an endpoint, field, or version that consumers depend on.
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 deprecation Removing API surface breaks whoever depends on it, and for public APIs you often cannot see or contact all of them. Deprecation is the process that gets consumers moved off before you remove, through clear signals, measured usage, and a timeline long enough to migrate but firm enough to actually end. ## Method 1. **Signal deprecation in-band.** `Deprecation` and `Sunset` HTTP headers (RFC standards) on responses from deprecated endpoints, `@deprecated` in schemas (GraphQL, proto: see graphql-schema-design, grpc-services), and deprecation notices in docs (see api-reference-docs): so consumers discover the deprecation programmatically and in documentation, not by surprise when it breaks. The signal reaches the machine and the developer. 2. **Measure who still uses it.** Track usage of the deprecated surface by consumer (see observability, api-versioning's usage tracking): you cannot end a deprecation you cannot measure, because you never know if anyone still depends on it. Usage data tells you who to contact and when it is safe to remove. 3. **Provide the migration path before deprecating.** The …

How to install
mdr add amey-thakur/ai-skills/api-deprecation@sha256:77799d36afa986aeThe line at the top of this page pins the label git:20260728.fac4544, 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.
