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 serialized for the host

Under the hood
Useful2 Signal3
Permissions

Permission rules sent to the host omit allow and environment lists for unpermitted callers.

What

Permission rules sent to the host are now assembled into a block of allow, soft-deny, hard-deny and environment lists. When the caller is not permitted, the allow and environment lists are omitted entirely, and nothing is sent at all when every list is empty.

Details
  • The accompanying check treats the auto and bypassPermissions modes identically.
Evidence

hardDeny

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