cat ~/.claude/skills/diagrams/mermaid-er-diagrams.md            # Database schema

Document Feature Implementation

Sequence: Flowchart → Sequence → State

cat ~/.claude/skills/diagrams/mermaid-flowcharts.md             # Business logic
cat ~/.claude/skills/diagrams/mermaid-sequence-diagrams.md      # Service interactions
cat ~/.claude/skills/diagrams/mermaid-class-state-diagrams.md   # State management

Project Planning

Sequence: Mindmap → Gantt → Timeline

cat ~/.claude/skills/diagrams/mermaid-specialized.md            # Brainstorm with mindmap
cat ~/.claude/skills/diagrams/mermaid-project-diagrams.md       # Schedule with Gantt
cat ~/.claude/skills/diagrams/mermaid-project-diagrams.md       # Roadmap with timeline

System Architecture Documentation

Sequence: C4 Context → C4 Container → Sequence

cat ~/.claude/skills/diagrams/mermaid-architecture-diagrams.md  # System context
cat ~/.claude/skills/diagrams/mermaid-architecture-diagrams.md  # Technology choices
cat ~/.claude/skills/diagrams/mermaid-sequence-diagrams.md      # Runtime behavior

Database Design

Sequence: ER → Class

cat ~/.claude/skills/diagrams/mermaid-er-diagrams.md            # Schema design
cat ~/.claude/skills/diagrams/mermaid-class-state-diagrams.md   # ORM models

Usage Instructions

  1. Auto-activation: This skill loads automatically when Claude Code detects diagram/visualization work
  2. Browse skills: Run cat ~/.claude/skills/diagrams/INDEX.md for full category overview
  3. Load specific skills: Use bash commands above to load individual diagram skills
  4. Follow workflows: Use recommended sequences for comprehensive documentation
  5. Combine diagrams: Multiple diagram types provide complete picture

Progressive Loading

This gateway skill (~200 lines, ~2K tokens) enables progressive loading:

  • Level 1: Gateway loads automatically (you're here now)
  • Level 2: Load category INDEX.md (~3K tokens) for full overview
  • Level 3: Load specific skills (~2-3K tokens each) as needed

Total context: 2K + 3K + skill(s) = 5-10K tokens vs 30K+ for entire category.

Quick Start Examples

"Create a flowchart for user authentication":

cat ~/.claude/skills/diagrams/mermaid-flowcharts.md

"Document API interactions":

cat ~/.claude/skills/diagrams/mermaid-sequence-diagrams.md

"Design database schema":

cat ~/.claude/skills/diagrams/mermaid-er-diagrams.md

"Show system architecture":

cat ~/.claude/skills/diagrams/mermaid-architecture-diagrams.md

"Create class diagram for ORM models":

cat ~/.claude/skills/diagrams/mermaid-class-state-diagrams.md

"Visualize project timeline":

cat ~/.claude/skills/diagrams/mermaid-project-diagrams.md

"Show data distribution":

cat ~/.claude/skills/diagrams/mermaid-charts.md

"Document Git workflow":

cat ~/.claude/skills/diagrams/mermaid-specialized.md

Best Practices

  1. Start broad, drill down: Architecture → Sequence → Class → Flowchart
  2. One diagram, one purpose: Don't mix abstraction levels
  3. Label everything: Relationships, transitions, axes, values
  4. Limit complexity: Split large diagrams into focused views
  5. Use GitHub/GitLab rendering: Diagrams auto-render in markdown
  6. Iterate in https://mermaid.live: Fast feedback loop

Mermaid.js Quick Tips

In Markdown files:

```mermaid
graph TD
    A --> B
```

Live Preview:

  • https://mermaid.live - Official editor
  • VS Code: Install "Mermaid Preview" extension
  • GitHub/GitLab: Auto-renders in README.md

Common Gotchas:

  • Use quotes for labels with spaces: A["Label with spaces"]
  • Escape special characters in labels
  • Check syntax highlighting for errors
  • Start simple, add complexity incrementally
