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.

Two spellings of the same plugin no longer count as two plugins

Plugins

Case or accent differences in a plugin name no longer create two conflicting enablement entries.

What

Plugin names are now folded to a single form before enablement is decided, so differences in letter case, Unicode composition, or a trailing marketplace suffix resolve to one entry instead of two conflicting ones.

Details
  • Folding applies NFC normalization plus lowercasing, and is tracked per settings layer.
  • If a folded name has both an enabled and a disabled entry, disabled wins.
  • Lookups walk the settings layers in order and can fall back to a related marketplace key.

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