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 v2.1.227

SendUserFile guidance now asks for deliverables as they are produced

Useful3 Signal2
File Delivery

Claude now sends you files as it produces them, not just the final deliverable.

What

The tool description that tells Claude when to send you a file was rewritten. It previously fired only when the file was the deliverable; it now covers any file you would want to see, sent as it is produced rather than batched at the end.

Details
  • explicitly warns off routine working files: "scratch files, debug output, partial fragments, or every incremental save"
  • also warns against re-sending a file that has not meaningfully changed since the last send
Evidence

Send deliverables as they are produced, not batched at the end of the task

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