What it does
MANDATORY prerequisite, load this skill BEFORE every `generate_diagram` tool call. NEVER call `generate_diagram` directly without loading this skill first. Trigger whenever the user asks to create, generate, draw, render, sketch, or build a diagram, flowchart, architecture diagram, sequence diagram, ERD or entity-relationship diagram, state diagram or state machine, gantt chart, or timeline. Also trigger when the user mentions Mermaid syntax or wants a system architecture, decision tree, dependency graph, API call flow, auth handshake, schema, or pipeline visualized in FigJam. Routes to type-specific guidance, sets universal Mermaid constraints, and tells you when to use a different diagram type or skip the tool entirely (mindmaps, pie charts, class diagrams, etc.).
generate-diagram
You MUST load this skill before every generate_diagram tool call. Skipping it causes preventable rendering failures and low-quality output.
generate_diagram takes Mermaid.js syntax and produces an editable FigJam diagram. This skill routes you to the right per-type guidance and sets universal constraints.
Step 1: Is generate_diagram the right tool?
Supported diagram types
flowchart, sequenceDiagram, stateDiagram / stateDiagram-v2, gantt, erDiagram.
Unsupported, don't call the tool
If the user wants any of these, tell them directly that generate_diagram doesn't support it instead of calling the tool and failing:
- Pie chart, mindmap, venn diagram, class diagram, journey, timeline, quadrant, C4, git graph, requirement diagram
When to push the user to edit in Figma
The tool cannot:
- Change fonts on an existing diagram
- Move individual shapes
- Edit a diagram node-by-node after generation
If the user asks for any of those on an existing diagram, recommend they open the diagram in Figma and edit there. For content-level changes, it's usually faster to regenerate.
Step 2: Pick the diagram type
Lightweight routing, use the first match.
