Use when the user asks to map, chart, diagram, visualise or plan something in Builderii.\n---\n\n# Draw a diagram in Builderii\n\n1. **Pick the kind.** A process or decision → flowchart (`create_flowchart`). Ideas around a topic → mind map (`create_mindmap`). Who calls whom, in order → sequence diagram (`create_sequence_diagram`). Pages of a site → sitemap (`create_sitemap`). Work over time → roadmap (`create_roadmap`, real dates). Tables and keys → database diagram (`create_database`, or paste SQL / a Prisma schema in `sql`). Mermaid you already have → `import_mermaid`.\n2. **Which board.** Use the board the user named; otherwise `create_board` with a specific name (kind `flowchart` or `mindmap` where it fits).\n3. **Write the structure.** Short labels in the user's words. Flowcharts: a start and an end, decisions with labelled arrows (yes / no), 5 to 20 steps. Mind maps: one central idea (parent `\"\"`), 4 to 7 branches, 2 to 4 ideas each. Sequence diagrams: participants in order, then messages (`sync`, `async`, `reply`). Builderii lays everything out, so give no coordinates.\n4. **Changing one that's there:** `list_diagrams`, then `get_diagram` for its ids, then the matching `update_*` with its `ref` — only the changes for flowcharts, mind maps and brainstorms; the whole diagram (keeping ids) for sequence diagrams, sitemaps, roadmaps and database diagrams. Don't draw a second copy.\n5. **Or let Builderii's AI draw it:** `generate` with the `type` and a prompt (pass `diagram` to change one). If it answers `working`, call `get_ai_job` shortly after.\n6. **Confirm** in a line or two what you drew, with the board's link.\n"
