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.

Storage subscriptions reject marketplace caches and append-only streams

Under the hood
Useful1 Signal3
Internals

Storage subscriptions refuse marketplace caches and append-only streams, and transcripts must name one session.

What

The subscribe path now validates requests and refuses ones aimed at cached plugin-marketplace data or at line-append streams, and only serves transcript subscriptions narrowed to a single session. The check is unconditional.

Details
  • Refused: keys or scopes in the marketplace cache namespace, covering the tree, its files and a manifest synthesized from them.
  • Refused: subscriptions to line-append streams.
Evidence

subscriptions to a marketplace tree, its files or a synthesized manifest are not served

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