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.

Conversation messages moved into a store

Under the hood
Useful2 Signal2
Session State

Your conversation messages now live in a per-session store that keeps token counters in step.

What

The interactive session no longer holds its message list in a React reference; a per-session store holds it and roughly 50 call sites read a snapshot from it. Every write also records the message count and an estimated token count into transcript state, keeping the tool-use and token counters in step with the messages.

Evidence

progress: { toolUseCount: 0, ...i.progress, tokenCount: n }

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