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.

Hook telemetry records a resolved hook name

Under the hood
Useful1 Signal1
Hooks

Hook telemetry now names the specific hook instead of the event that fired it.

What

The name reported when a hook runs is now computed rather than passed straight through, so the telemetry identifies the specific hook instead of the event that fired it.

Evidence

hookName: Vxt(R, u)

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