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.

Fleet view attaches are instrumented with a gesture record

Under the hood
Useful1 Signal0
Background Tasks

Opening a job from the fleet view is now traced end to end for diagnostics.

What

Opening a job from the fleet view now mints a gesture record so the attach can be traced end to end.

Details
  • A gesture id and start timestamp are minted, and a gesture sidecar record is written with surface "fleet".
  • gestureId and gestureT0 are passed through the attach dispatch.
  • The record is cleared on Ctrl-C or Escape, on selection movement, and on respawn failure including fork_transcript_never_materialized.
