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.

Permission rules are screened before they leave the machine

Permissions

Permission rules that reach outside the project or only fit your device are not forwarded to the cloud.

What

Each permission rule forwarded to a cloud session is classified first. Rules that reach outside the project are dropped as rooted, rules that only make sense on your own device are dropped as device, malformed rules as invalid, and rules past the count or length caps as over_cap. The rest are kept.

Details
  • Screening walks through wrapper commands (sudo, doas, env, timeout, xargs and others) to find the real command underneath.
  • It knows a large table of network-capable commands including curl, wget, ssh, psql, mongosh and invoke-webrequest.
  • It also flags arguments that bind a server to any address, such as --host, --bind or HOST= with values like 0.0.0.0, :: or localhost.
  • Counts of what was dropped are reported as droppedRooted, droppedDevice, droppedInvalid, droppedOverCap and droppedGuarded.

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