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.

Hook results say when the hook was backgrounded

You'll notice
Useful3 Signal2
Hooks

A hook left running in the background is now flagged as backgrounded instead of looking finished.

What

A hook that is detected as async and allowed to keep running now reports backgrounded: true alongside its stdout, stderr and exit status, so a hook left running is distinguishable from one that finished.

Details
  • When sync execution is forced, the hook is waited on to completion instead and logs that it is doing so.
Evidence

Hooks: Detected async hook but forceSyncExecution is true, waiting for completion

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