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.
When a hook produces invalid JSON output, the error message now says "The hook's output was:" (previously "The hook's stdout was:"), more accurately reflecting that output may come from various sources.
Evidence
Error message (search for "The hook's output was:")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
