- Introduced new core search tools in the Report Agent: InsightForge for deep insights, PanoramaSearch for comprehensive views, and QuickSearch for rapid queries. - Updated the Report Agent to prioritize tool usage for data retrieval, ensuring all report content is based on simulation results rather than internal knowledge. - Enhanced the ZepToolsService with methods for InsightForge and PanoramaSearch, allowing for multi-dimensional queries and historical data retrieval. - Improved documentation to reflect the new functionalities and usage guidelines for the Report Agent and Zep tools.

【最重要的规则 - 必须遵守】
|
||
═══════════════════════════════════════════════════════════════
|
||
|
||
1. 【必须调用工具获取数据】
|
||
- 你正在撰写的是基于模拟结果的分析报告
|
||
- 所有内容必须来自模拟图谱中的真实数据
|
||
- 禁止使用你自己的知识来编写报告内容
|
||
- 每个章节至少调用1-3次工具获取相关信息
|
||
|
||
2. 【必须引用模拟结果原文】
|
||
- 检索到的事实原文是最有价值的内容
|
||
- 在报告中使用引用格式展示这些原文,例如:
|
||
> "原文内容..."
|
||
- 这些原文证明了模拟的真实效果
|
||
|
||
3. 【尊重模拟结果】
|
||
- 报告内容必须反映模拟中实际发生的情况
|
||
- 不要添加模拟中不存在的信息
|
||
- 如果某方面信息不足,如实说明
|
||
|
||
═══════════════════════════════════════════════════════════════
|
||
【可用检索工具】(建议每章节调用2-5次)
|
||

|
||
|
||
{self._get_tools_description()}
|
||
|
||
【工具使用建议】
|
||
- insight_forge: 用于深度分析,会自动分解问题并多维度检索
|
||
- panorama_search: 用于了解全貌和演变过程
|
||
- quick_search: 用于快速验证某个具体信息

3. Observation: [分析工具返回的结果]

1. 内容必须基于工具检索到的模拟数据

3. 使用Markdown格式:

- 使用 > 引用重要原文
|
||
- 使用 **粗体** 强调关键信息

- 使用列表组织要点

4. 保持与其他章节的逻辑连贯性
