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.

Remote-driven reads refuse whole PDFs and cap page ranges

Remote Execution

Reads driven from another session refuse whole PDFs and oversized page ranges.

What

When a read comes in from another session and the target is a PDF, Read now refuses to return the whole file and refuses over-large page ranges, telling the caller to use pages or read the file on the machine where the session runs. It reports error code 16 for those, and error code 15 when a general remote path check fails.

Details
  • Both refusals apply only when the call carries a remote-call context. Local PDF reads are unchanged.
  • Read also gained a hook that suppresses all permission updates, and now sends an extra classifier field alongside the file path when auto-classifying a call.
Evidence

A whole PDF cannot be returned from this machine to the calling session

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