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.

Five new telemetry events for cross-machine file sync

Under the hood
Useful2 Signal4
Directory Sync

Cross-machine file sync now reports five new events covering disagreement, mid-turn sync and file handoff.

What

Sync between machines now reports a barrier event plus events for frame disagreement, mid-turn sync, and publishing or taking in files between tool calls. The barrier event records whether both sides agree on file state ("up", "down" or "both"), why they do not (peer too old, peer stale, no frame of our own, peer does not take files), plus timing and event counts. Reason strings pass through an allow-list that maps anything unrecognised to "other".

Details
  • No gate; emitted inside a try/catch on the sync path.
