# Message Chunker - 消息分段工具
智能分段发送长消息，确保每条消息不超过平台限制。
## 触发条件
当消息满足以下任一条件时自动分段：
- 消息长度超过 4000 字符
- 包含多个独立章节/表格
- 发送失败（Status 400）后重试
## 平台限制
| 平台 | 单条限制 | 建议 |
|------|---------|------|
| 飞书 | ~4KB | 每条≤4000字符 |
| Telegram | 4096字符 | 每条≤4000字符 |
| Discord | 2000字符 | 每条≤1900字符 |
| WhatsApp | 65536字符 | 较宽松 |
## 分段规则
### 1. 按章节分段
```
## 章节1
内容...
--- 分段 ---
## 章节2
内容...
```
### 2. 按表格分段
```
表格1内容...
--- 分割 ---
表格2内容...
```
### 3. 按段落分段
- 优先在 `---` 分隔线处分段
- 其次在空行处分段
- 避免在句子中间分段
## 使用方法
### 自动模式（推荐）
在回复长消息时，Agent会自动判断并分段：
```
# 第1条消息（分段1/n）
内容...
# 系统自动发送第2条
内容续...
# 系统自动发送第3条
内容续...
```
### 手动标记分段
在消息中插入分段标记：
```
{{CHUNK}}
```
Agent会在标记处自动分段。
## 示例
**原始长消息**（10KB）：
```
# 汇报
## 第一部分
[大量内容]
## 第二部分
[大量内容]
## 第三部分
[大量内容]
```
**分段后**：
```
第1条: # 汇报\n## 第一部分\n[大量内容]
第2条: ## 第二部分\n[大量内容]
第3条: ## 第三部分\n[大量内容]
```
## 配置
在 `TOOLS.md` 中可自定义：
```yaml
message-chunker:
maxChunkSize: 4000 # 单条最大字符数
splitOnHeadings: true # 在标题处分段
splitOnTables: true # 表格后分段
includeContinuation: true # 添加"续"标记
```
## 注意事项
1. **不要过度分段** - 能合并的内容尽量合并
2. **保持完整性** - 单个表格不要拆分
3. **添加续接标记** - 让用户知道还有下文
4. **重试机制** - 分段后仍失败则记录到失败队列
