What this skill does
EOL Checklist Purpose Turn a sunset decision into a phase-gated operational plan: what must happen, in which lifecycle phase, and who owns it. The output is a working checklist — sticky-note-sized items, each with a verb and a named function — not a strategy document. The checklist is sized to the sunset. A deprecated internal tool gets a dozen items across three phases. A regulated hardware line gets a cross-functional playbook across six phases with gate criteria between them. Both are correct; using the wrong one is the failure. Input Works best with: The product being sunset and any dates you're already committed to. Also useful: Customer and revenue scale, whether a replacement exists and how ready it is, contract or regulatory obligations, and whether hardware, inventory, or channel partners are in play. 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. Arriving empty-handed? That works too. The skill asks up to three questions — what's being sunset and at what scale, whether there's a replacement, and what hard deadlines exist — then picks a level and builds. Unknowns become labeled assumptions rather than blockers. Example invocations: EOL checklist for our legacy reporting module, shutting down Dec 31, ~400 accounts. Build the heavy checklist for a hardware retirement — service contracts, 8 resellers, UL certified. --- Key Concepts Right-Size Before You Build Not all EOLs play out the same. Most land in the middle. …
