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.

Image Size Validation

What

Validates image sizes before sending to the API and provides clear error messages when images exceed limits.

Details
  • Checks base64-encoded image sizes against API limits
  • Provides human-readable size information (KB/MB) in error messages
  • Reports which specific images are too large when multiple exceed limits
  • Suggests resizing images before sending
Evidence

urB() at line 278763 (image validator, contains "exceeds API limit")

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