Claude Code v2.1.251 28 Aug 2026

Clearer error when two marketplaces claim the same install directory

You'll notice

Useful2 Signal1

Plugins

If two marketplaces claim one directory, the error now names the other one.

What

Before refreshing an official or managed marketplace, Claude Code now confirms the directory on disk actually belongs to that marketplace rather than merely sitting under the expected root, and if it belongs to a different registered marketplace the error names it.

Details

Runs on both single and bulk marketplace refresh.

Evidence

it belongs to the registered marketplace

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