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.

Memory-store 404s distinguish "store not provisioned" from a missing document

Under the hood
Useful2 Signal0
Memory

Memory errors now tell you whether the whole store is missing or just a document.

What

A 404 from the memory backend now says whether the store itself does not exist or just the document.

Details
  • The not-found error takes a kind, defaulting to "document"; memory-backend list and read paths construct it with "store".
  • Listing accepts size_bytes as a fallback when content_size_bytes is absent.
  • Listing now also records updated_at.
Evidence

(store not provisioned)

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