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 errors now say what to do based on where the plugin came from

Plugins

Plugin load errors now give advice matched to how the plugin was installed, including synced copies being shadowed.

--plugin-dir
What

When a plugin does not load, the advice you get depends on how it was installed: passed with --plugin-dir, picked up from a skills directory, or synced from claude.ai. Shadowed synced plugins get their own named warning explaining that the local copy of the same name takes precedence.

Details
  • Plugin sources gained readable labels, including "plugins synced from your claude.ai account".
  • The pluginRoot field in a marketplace definition now has a much fuller schema description.

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