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.

Directory ownership verification helper

Permissions

A new check refuses directory paths unless every segment is owned by you and not a symlink.

What

A new check walks a directory path one segment at a time and refuses it unless every segment is owned by the current user and is not a symlink, finally confirming the resolved real path matches the expected target. On Linux and WSL it uses open-by-handle checks; elsewhere it falls back to creating the directories and stat-checking them.

Details
  • No code in this build calls it, so nothing yet routes through this stricter check.
Evidence

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