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.

Child-session supervisor logs turn state

Under the hood
Useful1 Signal3
Subagents

The supervisor now records what each child session is doing between turns.

What

The supervisor that runs child sessions now records what each child is doing between turns, which is groundwork for surfacing that state rather than something visible yet.

Details
  • It classifies follow-up turns against new ones, notes whether a child has stopped at a prompt or is still working, and records child exit.
  • Stream events flagged as coming from a sub-agent are now ignored by this path.
Evidence

child parked at a prompt

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