What problem does it solve? Session-based task lists disappear when a session ends, and parallel work across machines or agents silently duplicates effort. This Skill provides a durable, git-backed tracker for finding, claiming, and closing work items so ownership and progress survive across workstations, agents, and review rounds. ## Core Features & Use Cases - Durable context packs: Each work item is a pack capturing what done looks like, established facts with dates and evidence, rejected approaches, and verification steps. - Claim and closeout protocol: Claiming pushes to the remote so simultaneous starts collide instead of duplicating work; closing enforces acceptance gates and moves packs to done/. - Index and validation tooling: The index.py tool lists, shows, claims, releases, and closes packs, and validates the tracker with --check. - Use Case: Starting a session cold with no idea what is in flight, you list open packs, read one fully, claim it (which pushes immediately), and keep the claim through implementation, CI, and review until agreed acceptance is met. ## Quick Start Ask the agent to list the open todo packs, show the details of one item, and claim it so the claim is pushed to the shared tracker.
