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.

Emptied messages are explicitly not treated as subscriptions

Under the hood
Useful1 Signal2
Permissions

A tool result now spells out that a blanked message means nothing was sent and nothing subscribed.

What

A fixed tool result now states that when a permission handler blanks out a message, nothing was sent and no idle subscription was created, closing off an ambiguous reading of that case.

Evidence

a blanked delivery is never reinterpreted as a pure subscription

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