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.

Claude Code v2.1.251

Writes re-check that the path still lands in an allowed directory

You'll notice
Useful3 Signal2
File Tools

Writes re-check the path still lands in an allowed directory right before applying.

What

Just before applying a write, the tool re-resolves the file path and confirms it still falls inside the directories edits are permitted to touch, refusing the write with an explicit message if it does not.

Details
  • Runs unconditionally on the write path, as part of the permission check used in accept-edits mode.
  • Refusal message: the path resolved outside the directories edits may land in, and the edit is not applied.
Evidence

when this edit was checked the path resolved outside the directories edits may land in; not applying it

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