write-acceptance
Write docs/<feature>/ACCEPTANCE.md — the ordered checklist a person works through by hand to deploy, test and accept finished work, because a machine could not do it. Use at the end of every implementing skill (execute-plan, execute-roadmap, build-feature), or when the user invokes /write-acceptance <feature> or asks for a test plan, an acceptance checklist, or "tell me how to verify this". Covers only what could not be automated — consoles and accounts, physical devices, GUI surfaces, two-machine and multi-user cases — with copy-pasteable commands, the exact observable that counts as evidence, and what you expect back. The reader may be the user or a tester who has never seen the feature. For handing unfinished work to the next agent, use write-handoff instead.
