What

A new internal helper resets certain permission settings (the alwaysAllowRules.command list and a pollEventDeliveryGuard marker) on the tool-permission context. Behind a new flag called tengu_iridescent_pascal, this reset can now be skipped and the existing context reused when nothing actually needs to change. When a caller explicitly opts out of the reset, it can instead set the poll-event-delivery guard directly.

Why

Skipping unnecessary resets avoids rebuilding the permission context on every call. Nothing has been read yet about how this flag is currently set for this site's account, so its effect for readers isn't yet known.

Read once, for one account on one subscription tier, against v2.1.280. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns nothing at all, having stopped carrying it for tengu_iridescent_pascal, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
