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.

Directory sync reports more about how a sync started

Under the hood
Useful2 Signal2
Directory Sync

Directory sync events now record how a sync started and whether another window is syncing too.

What

Sync status events now carry whether this was the first upload, how many files synced, whether another window is syncing the same directory, and whether the sync started from an upload. The state validators also accept a worker note that a sync halted because it failed to start.

Details
  • New event fields: first_upload, synced_files, other_window, started_from_upload.
  • The halted state accepts the reason start_failed.
Evidence

started_from_upload

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