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.

Messages to a cloud session wait until it has your local files

Directory Sync

Messages to a cloud session wait until your uploaded files have actually landed there.

What

When directory sync is on, a message you send to a cloud session is held until the session confirms it applied the files uploaded from your machine, polled with exponential backoff up to a cap. If that never happens you get a plain-language explanation instead of silence.

Details
  • Timeout produces its own message; a partial apply names how many files could not be fetched.
  • Each container-side refusal maps to a sentence, covering a bundle timeout, the uploaded state not being a descendant of what the session has, a dirty working tree, a refused checkout and a git timeout.
  • Two new telemetry events record the wait and each held send.
  • Only sessions with directory sync active reach this path.
