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.

Subagent prompt — file-writing note clarified

The instruction telling subagents not to write report/summary/analysis files has been clarified to note that writing files as input to another tool is acceptable.

Details
  • Old: "Do NOT write report/summary/findings/analysis .md files. Return findings directly..."
  • New: "...Return findings directly... (Files written as input to another tool are fine; this note is about report files.)"
Evidence

Prompt text change (search for "Files written as input to another tool are fine")

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