# Team Board (shared claims + shared item memory) <!-- routing-eval reads this line; it lives in the BODY so the always-on skill LISTING stays inside Claude Code's budget (1% of the context window) — an overflowing listing gets descriptions truncated or dropped, which strips the very keywords a match depends on. --> Trigger phrases: "team board", "who is working on", "claim", "take this item", "pick up a task", "sprint item", "release the item", "hand the item over", "is anyone on", "board" ## The problem this closes Every teammate runs the kit **locally**. `docs/PLAN.md` and `docs/SESSION_STATE.md` are gitignored, so the fact that Ali started item #1 two hours ago exists nowhere the other sessions can see. Two people start the same item; a blocked item gets picked up before its dependency lands; whoever inherits half-finished work rebuilds the context from scratch. The board makes those three facts shared. ## The engine (all commands go through it) `bash .claude/hooks/board.sh <cmd>` — `status` · `show <id>` · `claim <id>` · `done <id> [note]` · `drop <id> <note>` · `note <id> <text>` · `add <id> <title> [deps] [external]` · `init` · `sync`.

A claim is a commit pushed to that ref, and `git push` is fast-forward-only: when two people claim the same item f...
