DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

What
Filesystem checks now separate "this path escapes the allowed directory" from "this path could not be confirmed to be inside it", the latter carrying a machine-readable code.

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