A server-controlled switch is a setting Anthropic's servers can turn on or off. Both count as on if the server sends nothing. The second one's name points to colouring of code.\n\n**Why**\n\nBoth are on unless the server says otherwise, so the VS Code extension may behave differently without any change on your part.\n\n- Flag `tengu_vscode_code_colors`: Not enough to say (read for one account on one subscription tier against v2.1.311; this account: no value returned, anonymous baseline: no value returned, compiled default: on) 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- Flag `tengu_optimized_puzzle`: Not enough to say (read for one account on one subscription tier against v2.1.311; this account: no value returned, anonymous baseline: no value returned, compiled default: on) 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: IDE Integration\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
