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 names starting with a dot, or matching the sync directory, are rejected

Plugins

Plugin names starting with a dot or matching the sync root are now rejected.

What

Plugin-name validation now rejects names beginning with . and names that fold to the reserved spelling used for the plugin sync root, with an explanation that such directories are never picked up as plugins. Previously only path separators were checked.

Details
  • Backed by a new shared module of name-safety helpers covering reserved-name folding and Windows reserved device names.
Evidence

those directories are never loaded as plugin adoptions

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