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.

Read Tool Guidance Updated

The Read tool system prompt now encourages partial file reads when the needed section is known.

What changed:

  • Added: "When you already know which part of the file you need, only read that part. This can be important for larger files."
  • This supplements the existing guidance about offset/limit parameters
Evidence

Read tool guidance (search for "When you already know which part of the file you need")

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