If a diagram can't be laid out or is too large, it's left as plain text instead.\n\n**Why**\n\nThis lets you see an actual diagram in the terminal instead of raw Mermaid markup, making flowcharts and sequence diagrams in a response easier to read at a glance. Whether this is active for a given account depends on a setting, `tengu_mermaid_mod`, which nothing has yet been read about.\n\n- Flag `tengu_mermaid_mod`: Not enough to say (read for one account on one subscription tier against v2.1.277; this account: no value returned, anonymous baseline: no value returned, 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: Terminal Rendering\n- Tier: You'll notice\n- Useful: 5\/5\n- Signal: 4\/5"}
