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.

More detail in existing telemetry events

Under the hood
Useful1 Signal2
Telemetry

Several internal reports gained detail, including dropped event batches and whether a live artifact was adopted.

What

Several events gained fields: the byte watchdog now reports how long it slept, how many bytes arrived and time to first byte; internal event batches dropped after a 4xx are counted and exposed so a flush can confirm it landed; the session-memory viewer close event adds an unrated count; the device bridge start event adds where the account came from; artifact hand-off events record whether a live artifact was adopted or undisclosed.

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