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.
MIME Type Database Removed (Bundle Size Reduction)
What's wrong with this entry?
Anonymous. No account, no email.
The full IANA MIME type database (~4000+ entries) has been replaced with stubs that throw descriptive errors, significantly reducing bundle size. The stubs warn against relying on axios auto-multipart serialization.
Evidence
Stub implementation (search for "mime-types." and "is stubbed in this build")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
