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.

Claude Code v2.1.251

Plugin directories on network paths are now rejected

Plugins

Plugins installed from network shares or automounted paths are now refused.

What

When a plugin's location comes from running a shell command, Claude Code now refuses paths that are Windows UNC shares or automounted network locations, and refuses paths reached through a symlink that points to an untrusted network location. Both the resolved plugin directory and every entry inside it are checked.

Details
  • Always applied when resolving a command-sourced plugin; there is no override.
  • The refusal says the path is a network path (UNC or automount) and is not supported as a plugin directory.
Evidence

a network path (UNC or automount), which is not supported as a plugin directory

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