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.

Binary Content Handling

What

Improved detection and handling of binary file content, with disk-based storage for large binary results.

Details
  • Sophisticated binary detection using byte analysis (null bytes, control characters)
  • Extensive list of known binary file extensions (images, audio, video, archives, executables, etc.)
  • Binary content from tool results can be saved to disk and referenced by path
  • Support for Office documents, archives, and other binary MIME types
Evidence

Binary content (search for "Binary content (", "Binary content could not be saved to disk")

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