# update_checklist_item

`tools/call` · `POST /clanker/v1/tickets:update-checklist-item`

Check, clear, start, rename or retag an item of a ticket's checklist. Checking records you and your person as who did it. Mark a Clanker item in progress with inProgress: true when you start it, and check it when it is done. Do Clanker items. A Human item is a person's: check one only when your person approves it in your conversation and it is theirs to approve, passing their words as approval; you cannot clear, rename, retag or remove one. Hand over a Clanker item you cannot do by tagging it human. Only the fields given change. Returns the ticket with its checklists. Needs write access.

- Area: Planning
- Needs the write grant. Idempotent.
