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 for remote tools now match alias names

You'll notice
Useful4 Signal2
Permissions

Permission rules now match a forwarded tool's alternate names, so your rule applies to every spelling.

What

A permission rule can now refuse a forwarded tool call when it names any of the tool's alternate names, not just the exact name the call arrived under, so rules you wrote against one spelling take effect on the others.

Details
  • Refusal text now names the tool from the matching rule rather than the incoming call, and deny messages carry extra rule context.
Evidence

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