New flag can widen when the extended usage-limit header is sent

A server flag can widen when subagent requests send the extended usage-limit header.

The extended usage header can now be sent without a cached reason when tengu_smooth_harbor is on server-side.

What

The rule deciding whether nested and subagent queries send the extended usage-limit header was pulled into one helper. It previously required a cached reason that extra usage is disabled; now, when there is no such reason, the header can still be sent if tengu_smooth_harbor is on.

Details
  • tengu_smooth_harbor falls back to off, and is still combined with tengu_lantern_spool, which also falls back to off.
  • Nothing in the build turns either on, so absent remote config the behaviour is exactly what it was.

Feature flag
tengu_smooth_harbor Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.246: off

tengu_lantern_spool Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

What has happened since
Flag reading moved The flag server now returns off for tengu_lantern_spool, 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.
