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.

Huge hook output no longer floods error messages

You'll notice
Useful3 Signal1
Hooks

A hook that dumps huge output now gives you a readable error instead of a wall of text.

What

Oversized hook output and error stacks are now cut down the middle with a marker saying how many characters were removed, so a hook that dumps a large stdout produces a readable failure instead of a wall of text.

Details
  • The count in the marker accounts for characters already elided by nested markers, so it stays accurate.
  • Errors are formatted as name and message plus at most five stack frames, each clipped to a line length.
  • Applied to worktree-create hook failure output.
Evidence

characters truncated

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