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.

New hook events and compiled-in plugin admission defaults

Not switched on
Useful3 Signal5
Hooks Notable

Three new hook event names appear, and unverified plugins are still allowed to load.

UserPromptExpansion, TaskCompleted and TeammateIdle are registered as hook events.

What

The list of hook event names now includes UserPromptExpansion, TaskCompleted and TeammateIdle next to the existing PreToolUse, PermissionRequest and UserPromptSubmit. Separately, a map of reasons to block a plugin ships with manifest_invalid, disabled_by_default and will_not_load blocking, while identity_unverified and archive_not_probed do not: an unverified plugin identity or an unscanned plugin archive is not enough to refuse loading by default.

Details
  • Those admission values are build-time constants, not settings.
Evidence

identity_unverified: !1

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