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.

Plugin sync records each plugin's id in a sidecar file

Under the hood
Useful1 Signal2
Plugins

Plugin sync writes a small sidecar file recording each plugin's id.

What

Syncing plugins writes a small file next to the synced directory recording the plugin's id, skipping the write when it already matches. If something other than a file sits at that path, a directory there is moved to trash first.

Details
  • New telemetry for an invalid id, a failed write and a failed trash move.
  • The synced-plugin record now also stores the plugin id, the installed version and the requested version.
  • Runs only after the existing guard verification passes.
