Install the "mermaid" agent skill from https://github.com/WH-2099/mermaid-skill/tree/main/.claude/skills/mermaid. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Generate Mermaid diagrams from user requirements. Supports flowcharts, sequence diagrams, class diagrams, ER diagrams, Gantt charts, and 18 more diagram types. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"wh-2099-mermaid","task":"Install mermaid","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes.Supply asset profile

# Mermaid Diagram Generator
Generate high-quality Mermaid diagram code based on user requirements.
## Workflow
1. **Understand Requirements**: Analyze user description to determine the most suitable diagram type 2. **Read Documentation**: Read the corresponding syntax reference for the diagram type 3. **Generate Code**: Generate Mermaid code following the specification 4. **Apply Styling**: Apply appropriate themes and style configurations
## Diagram Type Reference
Select the appropriate diagram type and read the corresponding documentation:

## Configuration & Themes
- [Theming](references/config-theming.md) - Custom colors and styles - [Directives](references/config-directives.md) - Diagram-level configuration - [Layouts](references/config-layouts.md) - Layout direction and spacing - [Configuration](references/config-configuration.md) - Global settings - [Math](references/config-math.md) - LaTeX math support
## Output Specification
Generated Mermaid code should:
1. Be wrapped in ```mermaid code blocks 2. Have correct syntax that renders directly 3. Have clear structure with proper line breaks and indentation 4. Use semantic node naming 5. Include styling when needed to improve visual appearance
## Example Output
```mermaid flowchart TD A[Start] --> B{Condition} B -->|Yes| C[Execute] B -->|No| D[End] C --> D ```

Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Generate Mermaid diagrams from user requirements. Supports flowcharts, sequence diagrams, class diagrams, ER diagrams, Gantt charts, and 18 more diagram types. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"wh-2099-mermaid","task":"Install mermaid","agent":"codex","outcome":"success","install_used":true}.

# Mermaid Diagram Generator
Generate high-quality Mermaid diagram code based on user requirements.
## Workflow
1. **Understand Requirements**: Analyze user description to determine the most suitable diagram type 2. **Read Documentation**: Read the corresponding syntax reference for the diagram type 3. **Generate Code**: Generate Mermaid code following the specification 4. **Apply Styling**: Apply appropriate themes and style configurations
## Diagram Type Reference
Select the appropriate diagram type and read the corresponding documentation:

## Configuration & Themes
- [Theming](references/config-theming.md) - Custom colors and styles - [Directives](references/config-directives.md) - Diagram-level configuration - [Layouts](references/config-layouts.md) - Layout direction and spacing - [Configuration](references/config-configuration.md) - Global settings - [Math](references/config-math.md) - LaTeX math support
## Output Specification
Generated Mermaid code should:
1. Be wrapped in ```mermaid code blocks 2. Have correct syntax that renders directly 3. Have clear structure with proper line breaks and indentation 4. Use semantic node naming 5. Include styling when needed to improve visual appearance
## Example Output
```mermaid flowchart TD A[Start] --> B{Condition} B -->|Yes| C[Execute] B -->|No| D[End] C --> D ```
