What problem does it solve?
Product managers often produce mermaid diagrams that fail to render, choose the wrong diagram type for their message, or create diagrams that a simple list would communicate better. This Skill guides PMs through selecting the right diagram type, writing valid syntax, and validating output before embedding it in PRDs, specs, and roadmaps.
Core Features & Use Cases
- Diagram Type Selection: A selection guide and PM use-case reference map 15 mermaid diagram types (flowchart, sequence, state, Gantt, quadrant, ER, and more) to specific communication needs.
- Syntax Validity Rules: Six core rules covering label quoting, special character escaping, node declaration order, and per-type node limits prevent most rendering failures.
- Planning Worksheet and Validation: A fill-in worksheet forces node inventory and cardinal-rule checks before writing code, followed by a quality checklist covering rendering, accessibility, and readability.
- Use Case: A PM preparing a launch PRD uses the worksheet to plan a feature-approval flowchart, a Gantt launch timeline, a webhook sequence diagram, and a prioritization quadrant, then validates each in mermaid.live before embedding.
