Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionmermaidjs-v11Execute the skills CLI command in your project's root directory to begin installation:
Fetches mermaidjs-v11 from mrgoonie/claudekit-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate mermaidjs-v11. Access via /mermaidjs-v11 in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Create text-based diagrams using Mermaid.js v11 declarative syntax. Convert code to SVG/PNG/PDF via CLI or render in browsers/markdown files.
Basic Diagram Structure:
{diagram-type}
{diagram-content}
Common Diagram Types:
flowchart - Process flows, decision treessequenceDiagram - Actor interactions, API flowsclassDiagram - OOP structures, data modelsstateDiagram - State machines, workflowserDiagram - Database relationshipsgantt - Project timelinesjourney - User experience flowsSee references/diagram-types.md for all 24+ types with syntax.
Inline Markdown Code Blocks:
```mermaid
flowchart TD
A[Start] --> B{Decision}
B -->|Yes| C[Action]
B -->|No| D[End]
```
Configuration via Frontmatter:
```mermaid
---
theme: dark
---
flowchart LR
A --> B
```
Comments: Use %% prefix for single-line comments.
Convert .mmd files to images:
# Installation
npm install -g @mermaid-js/mermaid-cli
# Basic conversion
mmdc -i diagram.mmd -o diagram.svg
# With theme and background
mmdc -i input.mmd -o output.png -t dark -b transparent
# Custom styling
mmdc -i diagram.mmd --cssFile style.css -o output.svg
See references/cli-usage.md for Docker, batch processing, and advanced workflows.
HTML Embedding:
