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.

Your always-allowed command list can no longer grow while an injected event is being delivered.

What
The permission context used when checking a tool call gained a flag that marks a poll-event or empty dispatch delivery. While it is set, the layers that would normally inject or replace the list of always-allowed commands leave the context untouched, so the allowlist cannot grow during that delivery.
Details
Applies on every build; no setting turns it on or off.
