Source Intelligence

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.

Teammate messaging prompt no longer points at TaskUpdate

You'll notice
Useful2 Signal2
Agents

Teammate agents report progress with whatever task tools they have, or in plain prose.

What

Agents in a teammate conversation are now told to report progress through their task tools if they have any, and otherwise in plain prose, instead of being told to use TaskUpdate for status.

Evidence

report progress through your task tools if you have them, otherwise in plain prose

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