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 context attached to permission and request telemetry

Under the hood
Useful1 Signal2
Telemetry

Permission and request telemetry now carries more detail, including whether hooks ran.

What

Permission and tool events now carry hooks_applied and a snapshot of session state, request content events count narration blocks, MCP server-instruction changes report how many instructions were added, and the held, superseded and fallback-reask permission outcomes now share one common set of extra fields.

Evidence

hooks_applied

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