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.

macOS Sandbox Unix Socket Permissions

What

More granular Unix socket permissions in the macOS sandbox.

Details
  • Changed from broad network* permission to specific network-bind and network-outbound for Unix sockets
  • Adds AF_UNIX socket domain permission explicitly
  • Improves security by limiting socket access to specific paths
Evidence

Sandbox socket rules (search for "(allow system-socket (socket-domain AF_UNIX))")

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