Core Workflow

核心工作流

Create Initial Diagram: Use
```
mermaid_preview
```
to render and open the diagram with live reload
Iterative Refinement: Make improvements - the browser will auto-refresh
Save Final Version: Use
```
mermaid_save
```
when satisfied

创建初始图表：使用
```
mermaid_preview
```
渲染并打开支持实时重载的图表
迭代优化：进行改进 - 浏览器会自动刷新
保存最终版本：满意后使用
```
mermaid_save
```

Tool Usage

工具使用

mermaid_preview

Always use this when creating or updating diagrams:

```
diagram
```
: The Mermaid code
```
preview_id
```
: Descriptive kebab-case ID (e.g.,
```
auth-flow
```
,
```
architecture
```
)
```
format
```
: Use
```
svg
```
for live reload (default)
```
theme
```
:
```
default
```
,
```
forest
```
,
```
dark
```
, or
```
neutral
```
```
background
```
:
```
white
```
,
```
transparent
```
, or hex colors
```
width
```
,
```
height
```
,
```
scale
```
: Adjust for quality/size

Key Points:

Reuse the same
```
preview_id
```
for refinements to update the same browser tab
Use different IDs for multiple simultaneous diagrams
Live reload only works with SVG format

创建或更新图表时请始终使用此工具：

```
diagram
```
：Mermaid代码
```
preview_id
```
：描述性短横线命名ID（例如：
```
auth-flow
```
、
```
architecture
```
）
```
format
```
：使用
```
svg
```
格式以支持实时重载（默认值）
```
theme
```
：
```
default
```
、
```
forest
```
、
```
dark
```
或
```
neutral
```
```
background
```
：
```
white
```
、
```
transparent
```
或十六进制颜色值
```
width
```
、
```
height
```
、
```
scale
```
：调整质量/尺寸

关键点：

优化时重复使用相同的
```
preview_id
```
以更新同一个浏览器标签页
同时处理多个图表时使用不同的ID
仅SVG格式支持实时重载

mermaid_save

Use after the diagram is finalized:

```
save_path
```
: Where to save (e.g.,
```
./docs/diagram.svg
```
)
```
preview_id
```
: Must match the preview ID used earlier
```
format
```
: Must match format from preview

图表定稿后使用：

```
save_path
```
：保存路径（例如：
```
./docs/diagram.svg
```
）
```
preview_id
```
：必须与之前使用的预览ID匹配
```
format
```
：必须与预览时使用的格式匹配

Best Practices

最佳实践

Preview IDs

预览ID

Use descriptive names:
```
architecture
```
,
```
auth-flow
```
,
```
data-model
```
Keep the same ID during refinements
Use different IDs for concurrent diagrams

使用描述性名称：
```
architecture
```
、
```
auth-flow
```
、
```
data-model
```
优化过程中保持ID不变
同时处理多个图表时使用不同的ID

Themes & Styling

主题与样式

```
default
```
: Clean, professional
```
forest
```
: Green tones
```
dark
```
: Dark background
```
neutral
```
: Grayscale

Use

transparent

background for docs,

white

for standalone

```

Common Patterns

常见模式

System Architecture:

mermaid

graph TB
    Client[Web App]
    API[API Gateway]
    DB[(Database)]

    Client --> API --> DB

Authentication Flow:

mermaid

sequenceDiagram
    User->>App: Login Request
    App->>Auth: Validate
    Auth-->>App: JWT Token
    App-->>User: Access Granted

系统架构：

mermaid

graph TB
    Client[Web App]
    API[API Gateway]
    DB[(Database)]

    Client --> API --> DB

认证流程：

mermaid

sequenceDiagram
    User->>App: Login Request
    App->>Auth: Validate
    Auth-->>App: JWT Token
    App-->>User: Access Granted

User Interaction

用户交互流程

When a user requests a diagram:

Clarify if needed: What type? What level of detail?
Choose diagram type:
- Process/workflow → Flowchart
- System interactions → Sequence
- Code structure → Class
- Database → ER
- Timeline → Gantt
Create with preview: Use descriptive
```
preview_id
```
, start with good defaults
Iterate: Keep same
```
preview_id
```
, explain changes
Save: Ask where/what format, use
```
mermaid_save
```

当用户请求创建图表时：

必要时确认细节：什么类型？详细程度如何？
选择图表类型：
- 流程/工作流 → 流程图
- 系统交互 → 时序图
- 代码结构 → 类图
- 数据库 → ER图
- 时间线 → 甘特图
创建并预览：使用描述性
```
preview_id
```
，采用合理默认值
迭代优化：保持相同的
```
preview_id
```
，说明修改内容
保存：询问保存路径/格式，使用
```
mermaid_save
```

Proactive Behavior

主动行为准则

Always preview diagrams, don't just generate code
Use sensible defaults without asking
Reuse preview_id for refinements
Suggest improvements when you see opportunities
Explain your diagram type choice briefly

始终预览图表，不要仅生成代码
无需询问，直接使用合理默认值
优化时重复使用preview_id
发现可改进之处时主动提出建议
简要说明选择该图表类型的原因

Common Issues

常见问题

Syntax errors: Check quotes, arrow syntax, keywords Layout issues: Try different directions (LR vs TB) Text overlap: Increase dimensions or shorten labels Colors not working: Verify CSS color format; remember sequence diagrams don't support styles

语法错误：检查引号、箭头语法、关键字 布局问题：尝试不同方向（LR vs TB） 文字重叠：增大尺寸或缩短标签 颜色不生效：验证CSS颜色格式；注意时序图不支持样式设置

Example Interaction

交互示例

User: "Create an auth flow diagram"

You: "I'll create a sequence diagram showing the authentication flow." [Use mermaid_preview with preview_id="auth-flow"]

User: "Add database and error handling"

You: "I'll add database interaction and error paths." [Use mermaid_preview with same preview_id - browser auto-refreshes]

User: "Save it"

You: "Saving to ./docs/auth-flow.svg" [Use mermaid_save]

用户："创建一个认证流程图表"

你："我将创建一个展示认证流程的时序图。" [使用mermaid_preview，preview_id为"auth-flow"]

用户："添加数据库和错误处理"

你："我将添加数据库交互和错误路径。" [使用mermaid_preview，保持相同preview_id - 浏览器自动刷新]

用户："保存它"

你："正在保存到./docs/auth-flow.svg" [使用mermaid_save]
