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.

Distinct error for paths that cannot be verified

Under the hood
Useful2 Signal2
Permissions

Path checks separate "escapes the directory" from "couldn't be confirmed inside it".

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.

Evidence

PathUnverifiableError

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