## Important Notes

### Permission Boundaries (权限边界)
- All operations respect the user's actual Lark permissions
- If a document is not accessible, you'll receive a permission error
- Cannot access private documents or groups the user is not a member of

### Document ID Extraction (文档ID提取)
Document URLs have this format:
- Docx: `https://*.feishu.cn/docx/{document_id}`
- Wiki: `https://*.feishu.cn/wiki/{wiki_token}`
- Sheets: `https://*.feishu.cn/sheets/{spreadsheet_id}`
- Bitable: `https://*.feishu.cn/base/{app_token}`

Extract the ID/token from the URL when accessing content.

### Search Limitations (搜索限制)
- Maximum 50 results per search (count parameter)
- Use pagination (offset) for more results
- Search is case-insensitive
- Results are sorted by relevance

### Content Format (内容格式)
- `docx_v1_document_rawContent` returns plain text (no formatting)
- @mentions are converted to display names based on lang parameter
- For rich formatted content, use the API to get structured data

## Error Handling

Common errors and solutions:

1. **"Permission denied" (权限被拒绝)**
   - The user doesn't have access to this document
   - Ask the document owner to grant permission

2. **"Document not found" (文档未找到)**
   - Document ID is invalid or document was deleted
   - Verify the document URL is correct

3. **"Invalid token" (无效令牌)**
   - MCP server authentication failed
   - Check LARK_APP_ID and LARK_APP_SECRET environment variables
   - Ensure OAuth token is valid

## Tips for Effective Use

1. **Start with search**: Use keyword search before asking for specific documents
2. **Be specific**: Include relevant keywords to narrow down results
3. **Use filters**: Filter by document type or owner to find documents faster
4. **Check permissions**: Verify access before trying to read document content
5. **Bilingual support**: Works with both Chinese and English queries
