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 v2.1.30

PDF Page Range Support

What

The Read tool now supports reading specific page ranges from PDF files instead of requiring the entire document.

Usage
Read tool with pages parameter: "1-5", "3", or "10-20"
Details
  • New pages parameter accepts ranges like "1-5", single pages like "3", or spans like "10-20"
  • Pages are 1-indexed
  • Large PDFs (more than 10 pages) now require the pages parameter; reading without it will fail
  • Maximum 20 pages per request
  • For very large PDFs, a pdf_reference content type instructs Claude to use the pages parameter incrementally
Evidence

PDF page handling (search for "Invalid pages parameter" and "pages, which is too many to read at once")

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