Source Intelligence

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.

Plugins Notable

Marketplace plugins can be built by a local command, with a timeout and optional link mode.

What

A plugin marketplace entry can now use source: "command", a shell command that prints the absolute path of a plugin directory on stdout and exits 0. Claude Code copies that directory into its plugin cache, or links it in place with mode: "link". The command has a timeout in seconds, default 60 and capped at 600. Administrators can block it entirely with the managed settings disableCommandPluginSources or allowManagedHooksOnly.

Details
  • The command must print exactly one line, the absolute path of the plugin directory, and exit 0.
  • The command string is validated as printable ASCII before it runs.
  • mode: "link" is refused on Windows; the copy behaviour remains available there.
  • Every install and update through this source goes through the confirmation prompt described below.
Evidence

Shell command that prints the absolute path of the plugin directory on stdout (exactly one line) and exits 0.

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