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 event catalogue is rebuilt rather than cached

Under the hood
Useful1 Signal1
Hooks

The hook event table is rebuilt each time instead of cached; wording is unchanged.

What

The table describing every hook event, its summary, exit-code meaning and matcher rules, used to be cached against the sorted list of tool names. That cache and its reset method are gone and the table is now built fresh on each call. The events and their wording are unchanged.

Evidence

Before tool execution

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

Related

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
