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 load fails outright when the cache copy fails

Plugins

With the newer plugin storage layout, a failed cache copy now fails the plugin load and suggests reinstalling.

What

With the v5 plugin storage layout pinned on for a session, a plugin whose copy into the versioned cache fails is no longer run from the marketplace clone; it fails to load with an error suggesting a reinstall. Without that layout, the old warn-and-continue behaviour is unchanged.

Details
  • The fallback that ran the plugin directly from the marketplace clone is what the strict path removes.
  • Separately and unconditionally, claude plugin CLI failures are now split into expected failure results, which are logged, and unclassified errors, which are reported with a label naming the subcommand that produced them.
Evidence

Not loading it from the marketplace clone (strict plugin cache).

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