When it is not enabled, Claude is told to call it early access and never guess a variable name.\n\n**Details**\n\n- The gate itself is unchanged: the remote flag `tengu_walnut_spire`, which defaults to off, or the environment variable.\n\n**Evidence**\n\n`CLAUDE_CODE_WALNUT_SPIRE=1`\n\n- Flag `tengu_walnut_spire`: Off in both readings (read for one account on one subscription tier against v2.1.233; this account: off, anonymous baseline: off, compiled default: 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.\n- Area: Plugin Eval\n- Names: `CLAUDE_CODE_WALNUT_SPIRE`, `claude plugin eval`\n- Tier: Use it now\n- Useful: 3\/5\n- Signal: 5\/5"}
