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.

Clearer marketplace validation errors

Plugins

Marketplace validation errors now name the bad source and tell you how to fix it.

metadata.pluginRoot
What

A bare plugin source in a marketplace file now fails with a message naming the source and telling you to either use a ./relative/path or set metadata.pluginRoot. Reserved plugin names are also checked against a single table now instead of one rule per name.

Details
  • Reserved names covered by the table: inline, builtin and skills-dir.
  • Full message: Bare source name "${b}" requires metadata.pluginRoot. Use "./relative/path", or set metadata.pluginRoot (e.g. "./plugins") to allow bare names.
Evidence

Bare source name "${b}" requires metadata.pluginRoot. Use "./relative/path", or set metadata.pluginRoot (e.g. "./plugins") to allow bare names.

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