Create technical diagrams using diagramming languages like Mermaid, PlantUML, GraphViz, and others. Use when users request diagrams, flowcharts, sequence diagrams, architecture diagrams, ER diagrams, Gantt charts, mind maps, or any visual representation of systems, processes, or data structures. Trigger examples:"画一个系统架构图"、"创建一个流程图"、"生成一个时序图"、"帮我做个甘特图"。

When & Why to Use This Skill

This Claude skill empowers users to instantly generate professional technical diagrams using industry-standard languages like Mermaid, PlantUML, and GraphViz. It streamlines the visualization of complex systems, workflows, and data structures, making it an essential tool for developers, architects, and technical writers to enhance documentation and communication efficiency.

Use Cases

  • System Architecture: Designing and visualizing cloud infrastructures, microservices, and network topologies for technical proposals.
  • Software Development: Creating sequence diagrams and flowcharts to document logic flows, API interactions, and state machines.
  • Database Modeling: Generating Entity-Relationship (ER) diagrams to visualize database schemas and data relationships.
  • Project Planning: Producing Gantt charts and timelines to track project milestones, resource allocation, and schedules.
  • Knowledge Management: Building mind maps and organizational charts to structure complex ideas or team hierarchies.

Diagram Creator

Quick Start

Use Mermaid as the default choice - it's versatile, well-supported, and handles most diagram types:

graph LR
    A[开始] --> B{判断}
    B -->|是| C[执行]
    B -->|否| D[结束]

Tool Selection Guide

Default: Use Mermaid for most cases (flowcharts, sequence diagrams, Gantt charts, ER diagrams)

Alternative tools for specific needs:

  • Complex UML/C4: PlantUML
  • Network/Architecture: GraphViz (DOT)
  • ASCII art style: Ditaa
  • Timeline/Waveforms: WaveDrom
  • Full list: See TOOLS.md

Apply these colors for professional, consistent diagrams:

用途 颜色 HEX 场景
主色 深海蓝 #0052CC 核心系统、主要服务
辅色 天空蓝 #4C9AFF 子系统、API 网关
中性 浅灰 #EBECF0 背景、分组、边界
强调 活力橙 #FF991F 重点模块、第三方依赖
线条 深炭灰 #172B4D 连接线、文字、边框

Example

graph TD
    %% 定义样式
    classDef core fill:#0052CC,stroke:#172B4D,stroke-width:2px,color:#fff;
    classDef sub fill:#4C9AFF,stroke:#172B4D,stroke-width:1px,color:#fff;
    classDef container fill:#EBECF0,stroke:#172B4D,stroke-width:1px,stroke-dasharray: 5 5,color:#172B4D;
    classDef warn fill:#FF991F,stroke:#172B4D,stroke-width:2px,color:#fff;

    %% 图表内容
    subgraph VPC [云私有网络 VPC]
        LB(负载均衡 LB):::sub
        
        subgraph AppLayer [应用层 Group]
            API(API 网关):::sub --> Auth(认证服务):::core
            Auth --> Core(核心业务系统):::core
        end
        
        subgraph DataLayer [数据层 Group]
            DB[(主数据库)]:::core
            Redis(缓存 Redis):::warn
        end
    end
    
    User((用户)) --> LB
    LB --> API
    Core --> DB
    Core -.-> Redis

    %% 应用样式
    class VPC,AppLayer,DataLayer container;

Workflow

  1. Understand the diagram requirements and type needed
  2. Select appropriate tool (default: Mermaid)
  3. Design structure and layout
  4. Apply recommended colors for visual clarity
  5. Generate clean diagram code
  6. Validate syntax and readability

Output only the diagram code - no XML tags, no extra explanations.
