Unclear What either switch controls is not known, so it is unclear whether anything a user can see depends on them.

What

Claude Code contains two new switches that Anthropic's servers can set for each account:

  • tengu_serene_rain: an on/off switch. It is off unless it is switched on remotely, and a second condition must also hold before it has any effect. It read off for this site's account and for an account with no special settings.
  • tengu_spare_attic: a number setting. It is 0 unless a different value is sent remotely.
Why

Both switches are off by default, so nothing changes for most people unless the server turns them on.

Read from
Feature flag
tengu_serene_rain 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 v2.1.319: 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.

tengu_spare_attic 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 v2.1.319: not a boolean we can read

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.
