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.

Forwarded remote edits can be previewed against the local file

You'll notice
Useful3 Signal3
Remote Approvals

Approval dialogs for forwarded edits now rebuild the diff against your local copy of the file.

What

When a session running elsewhere forwards an Edit or Write call to your machine, the approval dialog now tries to rebuild the diff from your local copy of the file instead of showing only the remote preview. If the local rebuild is not possible it falls back to the remote preview and records why.

Details
  • The dialog looks the forwarded call up locally; when found it reports the preview source as local.
  • Fallback reasons recorded are lookup_error and local_read_failed.
  • A case where the edit produces no changes is explained to the user rather than shown as an empty diff.
  • Every outcome is reported to a new telemetry event; there is no feature flag on the reporting, but the local preview additionally needs the forwarded call to be held on this machine.
