What

When you cancel (Ctrl-C) while background tasks are running, Claude Code can now take one of two paths to stop those background agents, depending on a feature flag called tengu_zinc_harbor.

Why

This is internal groundwork for changing how background agents get stopped on cancel; it isn't yet active for general users.

Feature flag
tengu_zinc_harbor 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.

This account: off · anonymous baseline: off · compiled default in v2.1.275: off

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
