Plan the end-of-life for a product or feature — migration, communications, and timeline. A first-class PDLC phase, triggered when an initiative is net-negative.
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
# Sunset Product End-of-life is a normal PDLC outcome, not an admission of failure. When the Measure gate returns `sunset` (or when a product becomes net-negative), this skill produces the plan to retire it responsibly: migrate users, communicate, and wind down without breaking promises. ## Prerequisites - Apply the shared PDLC conventions in `skills/pdlc/references/shared.md`. - A `sunset` gate verdict, or a manual decision to retire, with `health-report.md` and `feedback-loop.md` as evidence. ## Steps 1. Confirm the sunset rationale and record it (the value is no longer there, the cost exceeds it, or it is being superseded). Reference the health/feedback evidence. 2. Identify affected users and data: who depends on this, and what must be migrated or preserved. 3. Define the migration path: where users go, what data exports exist, and the effort required. 4. Build the communication timeline: advance notice, deprecation notice, and final cutover date. State the notice period (give users enough time). 5. Define the ramp-down: feature flags, access controls, and the order in which capabilities are removed. …

How to install
mdr add tomzx/agents/sunset-product@sha256:1900c32d5f411d72The line at the top of this page pins the label git:20261007.b35fc4b, 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.
