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.

Plugin marketplace text is sanitised before display

You'll notice
Useful3 Signal2
Plugins

Plugin marketplace names and descriptions are cleaned before display, blocking escape sequences and text-direction spoofing.

What

Names, sources, versions and descriptions coming from marketplace metadata are cleaned before being printed in plugin list, detail, update and prune output, and marketplace names containing control or text-direction characters are now rejected outright. This blocks terminal escape sequences and right-to-left spoofing in third-party plugin metadata.

Details
  • The marketplace-name schema rejects control and bidirectional-formatting characters with the message quoted below.
  • The plugin update command path sanitises its messages too.
Evidence

Marketplace name cannot contain control or bidirectional-formatting characters

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