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.

Claude Code v2.1.242

PDF reads inside REPL results are capped with an explicit note

You'll notice
Useful2 Signal2
Elsewhere

Too many PDFs in one REPL result get dropped with a note telling Claude to read fewer.

What

When Read calls made inside a REPL produce more PDFs than the result can carry, the extras are dropped and replaced by a note that states the cap and tells Claude to read fewer PDFs per call, so the model can correct itself instead of silently losing documents.

Details
  • Parallel counters were added for omitted images and for image pages that failed to render.
Evidence

"type": "text"

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