Plan artifacts read CLAUDE_CODE_PLAN_ARTIFACTS and a gate that falls back to false, so it is off by default.
The thrifty-sonic experiment now only applies to a single model, and the plan-artifacts toggle no longer shares its gate.
- The thrifty-sonic check short-circuits unless the model resolves to
claude-opus-5, beforetengu_thrifty_sonicis consulted; its environment variable is unchanged. - Plan artifacts now read the environment variable
CLAUDE_CODE_PLAN_ARTIFACTSand the gatetengu_basalt_loom, which falls back to false, replacing thetengu_thrifty_sonicread that was there.
CLAUDE_CODE_PLAN_ARTIFACTS
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_thrifty_sonic Off by default, switched on for this accountThe shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

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_basalt_loom Not enough to sayNothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

Read once, for one account on one subscription tier, against v2.1.223. It isn't a statement about your account. What a flag value here can and cannot tell you
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.
