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.

Background Tasks

Background task snapshots and a GetTask tool are compiled off entirely.

Every entry point sits behind a helper compiled to literal false, with no flag name.

What

New code captures a finished background shell task, including a tail of its output, and attaches it to the task notification so it can be delivered as a tool result, with a matching GetTask tool added to the worker tool list. Every entry point sits behind a helper compiled to a literal false in this build, so none of it runs here and there is no flag name to turn it on.

Details
  • A withdrawal hook consumes the queued notification when the snapshot is delivered as a tool result instead.
Evidence

GetTask

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