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.

Status messages from nested sessions are passed up again

You'll notice
Useful3 Signal2
Compaction

Compaction status from a nested session is now shown in the session you are watching.

What

A status message produced inside a nested session used to be dropped. It is now re-emitted to the outer session along with the permission mode and the result or error from compaction, so a compaction that happened deeper down is visible where you are.

Details
  • The compaction error is only attached when an internal check allows it, so it can be stripped before the message leaves the session.
Evidence

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