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 can be installed from a command that prints a directory

Plugins Notable

Marketplaces can install a plugin by running a command that prints a directory path, with your consent.

What

Plugin sources now include command: a shell command that prints the absolute path of a plugin directory. It is re-resolved on install, on update and once per session in the background, takes an optional timeout, and a mode of copy or link decides whether the directory is copied into the plugin cache or used in place. Installing one asks for consent first.

Details
  • The command string must be printable ASCII and short enough for the consent prompt to display in full, so it can be read before you approve it.
  • Declining the consent prompt is recorded as command_source_declined.
  • link mode serves the plugin from the producer's directory rather than a cache copy.
Evidence

command must be printable ASCII (letters, digits, punctuation, single spaces) with no runs of 4 or more spaces

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