What
TaskUpdate is the tool Claude uses to change a task on the shared task list. It now carries a short hint about when to use it: "When you start, finish or drop a task on the task list". It also has its own id in Claude Code's list of tools.
When a task is assigned to a teammate, the message now names the assigning agent by its own name when that is known. Before, it used only the leader's name or "team-lead".
Why
The hint helps tool search, the way Claude finds tools that are not loaded upfront, to pick TaskUpdate at the right moment.
