Run a deprecation from usage telemetry through a hard sunset date, with migration tooling and staged comms, so a system retires without stranding its callers. Use when you own an API, endpoint, library, or service that must be turned off while other teams still depend on it.
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
# Deprecation program A deprecation announcement changes nobody's behavior. Teams migrate the week their code breaks, not the week you ask, so a "deprecated" label with no telemetry, no tooling, and no off switch becomes a maintenance tax you pay indefinitely. Run it as a program with a burndown and a real end date, not a wiki page and good intentions. ## Method 1. **Instrument the surface before you say a word.** Add per-caller telemetry: which team, service, and code path hits it, and at what rate. Tagged access logs or OpenTelemetry spans beat an aggregate counter, because "2M calls a day" names nobody to email. You cannot deprecate a caller you cannot identify. 2. **Publish a notice carrying a hard date and the replacement.** State the exact date the system stops answering, the migration target, and the reason. Emit the warning at the call site too: a `Sunset` response header (RFC 8594), a `@Deprecated` annotation, a startup log line. A notice with no date is a wish. 3. **Ship the migration, not just the docs.** Write the codemod (jscodeshift, OpenRewrite, a scripted sed pass), the shim, or the adapter that does the …

How to install
mdr add amey-thakur/ai-skills/deprecation-program@sha256:0f89abbba3ca963aThe 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.
