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.

Under the hood
Useful1Signal2
Permissions
A tool result now spells out that a blanked message means nothing was sent and nothing subscribed.
What's wrong with this entry?
Anonymous. No account, no email.
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.
