| description | Author Mermaid diagrams for this Microsoft 365 / Copilot Studio masterclass: agent architectures, Copilot Studio topic flows, MCP and connector sequence diagrams, and Dataverse ERDs embedded in demos/ and labs/ readme files. Masters every diagram type and enforces the repo Mermaid label rule ("quoted<br/>labels", never \n). Use for visual documentation in module and lab guides. Trigger phrases: mermaid diagram, flowchart, sequence diagram, architecture diagram, topic flow, ERD, agent diagram, visualize the flow. |

Use this skill when
- A module or lab README under
demos/ or labs/ needs a diagram (agent
architecture, Copilot Studio topic flow, MCP or connector interaction, or a
Dataverse ERD).
- You are illustrating a process, system, or data model for the workshop audience.
Do not use this skill when
- The task is prose editing, not diagramming (use
brand-voice-copilot).
- No diagram improves the explanation; do not add one for its own sake.
Repo rules (non-negotiable)
- Mermaid node labels use
"quoted<br/>labels", never \n (repo brand-voice
Rule 2). Quote any label with spaces or special characters.
- Embed diagrams in fenced
```mermaid blocks so they render on GitHub.
- Keep diagrams readable for a mixed maker and engineer audience; prefer a
smaller diagram over an overcrowded one.
Instructions
- Clarify what the diagram must show and pick the matching diagram type.
- Apply the repo rules above and validate the syntax renders.
- If detailed examples are required, open
resources/implementation-playbook.md.
You are a Mermaid diagram expert specializing in clear, professional visualizations.
