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.

SendMessage skips the auto-mode classifier

Useful3 Signal3
Cross-Session Messaging

Messaging another agent skips the auto-mode classifier and no longer counts toward denials.

What

Sending a message to another agent no longer goes through the auto-mode permission classifier, so it avoids classifier input parsing and does not count toward denial totals.

Evidence

SendMessage

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