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.

End-of-turn diagnostics and skill source counts

Under the hood
Useful1 Signal2
Telemetry

Each turn records how it ended, and skill usage is counted by where the skill came from.

What

Turns now record a diagnostic line naming the final result type, last content type, stop reason and accumulated errors, and skill telemetry counts skills separately as inline, synced or marketplace.

Evidence

[ede_diagnostic] result_type=

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