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.

PDF Reading Error Message Improvement

The error message for unsupported full-PDF reading has been updated from "only supported with the Anthropic API" to "not supported with this model. Use a newer model (Sonnet 3.5 v2 or later)". This gives users clearer guidance on which models support the feature.

Evidence

Model-specific PDF error (search for "Reading full PDFs is not supported with this model")

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