DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Teammates are only told about the task list when they can use it

Subagents

Spawned teammates only hear about the shared task list when they actually have task tools.

What

The instructions given to a spawned teammate now depend on whether that teammate actually has task tools. The task-list path and the line "Check the task list periodically. Create new tasks when work should be divided. Mark tasks resolved when complete." are only added when it does; previously both were sent unconditionally. A teammate without task tools also stops auto-claiming the next open task.

Details
  • A hasTaskListTools field on the team context attachment carries the answer, computed from the teammate's real tool surface.
  • Task tooling is gated: CLAUDE_CODE_ENABLE_TASKS can force it off, and the todo/task surface otherwise falls back to tengu_rosy_wren, which is false in this build.

hasTaskListTools

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
