What problem does it solve? It turns a planned milestone in a cairn-tracked repository into completed, verified code by driving the full implementation phase: branching, question gates, tests-first task execution, checkpoint commits, and status transitions, all recorded in the repo's markdown tracking files. ## Core Features & Use Cases - Branch and session management: Cuts or resumes a milestone branch from the synced default branch, handling both owner and guest (fork) collaboration modes with merge or rebase sync. - Tests-first autonomous task execution: Works tasks in order with tests first, runs the active toolchain profile's verify slot, and checkpoint-commits each task together with its milestone file update. - Gated plan amendments and audits: Handles minor and substantive plan amendments through question gates, runs fresh-context re-audits of amended acceptance criteria, and performs a claim audit of user-facing prose before review. - Use Case: A developer says "work on M107" and the skill resumes the milestone branch, runs the open question gate, implements remaining tasks with tests, and closes with a status table and the next command /milestone-review M107. ## Quick Start Ask the assistant to start or resume implementing a planned milestone by its ID, for example "work on M107" or "resume the milestone".
