Map a product's lifecycle stage and choose between extension, replacement, and retirement plays. Use when a product is maturing or declining and the next move isn't obvious.
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
# Product Lifecycle Plays ## Purpose Decide what to do with a product that has stopped growing. There are three plays — **extend**, **replace**, **retire** — and picking the wrong one is expensive in a different way each time. This skill gives you the stage diagnosis, the criteria that discriminate the plays, and the hazard register for the one that goes wrong most often. Most teams skip straight to a play. Someone says "let's rebuild it" or "let's kill it," and the argument that follows is about the answer rather than the diagnosis. The diagnosis is the work. ## Input **Works best with:** The product or product line, and the signal that prompted the question — flattening revenue, rising support costs, a competitor move, a strategy shift. **Also useful:** Revenue and margin trend, customer counts and concentration, support load, what else in the portfolio is adjacent, and how much investment appetite exists. Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended `ARGUMENTS:` line — counts as answers already given. Use it and skip whatever it covers; don't re-ask. …

How to install
mdr add deanpeters/product-manager-skills/product-lifecycle-plays@sha256:f917b60fa143cde8The line at the top of this page pins the label git:20260810.ba3fc8c, 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.
