What

The Kairos loop prompt check no longer reads tengu_kairos_loop_prompt from remote config and always returns false. The flag name is absent from this build.

Evidence

return we("tengu_kairos_loop_prompt", !1);

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

Read from
Feature flag
tengu_kairos_loop_prompt On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

What has happened since
Flag reading moved The flag server now returns on for tengu_kairos_loop_prompt, 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.
