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.

Rewritten Auto Memory Instructions

What

The auto memory system prompt has been completely rewritten with clearer, more actionable guidance.

Changes:

  • Simplified structure with clear "What to save" and "What NOT to save" sections
  • More specific guidelines about when to consult memory files
  • Explicit section for handling user requests to remember or forget things
  • Cleaner formatting with focused bullet points
Evidence

Auto memory prompt (search for "# auto memory")

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