+# Intent Tool
+
+本模块提供基于意图识别的股票因子检索能力。
+
+## 快速开始
+
+```python
+from veadk.tools.builtin_tools.intent_tool.governance import IntentGovernor
+from veadk.tools.builtin_tools.intent_tool.retriever import StockRetriever
+
+# 1. 初始化
+governor = IntentGovernor()
+# 指定 VikingDB 中的 Collection 名称
+retriever = StockRetriever(collection_name="stock_factors_kb")
+
+# 2. 用户提问
+query = "前2月销额累计值同比稳增的半导体股"
+
+# 3. 意图识别
+intent_result = governor.process(query)
+
+if intent_result["status"] == "PROCEED":
+    # 4. 执行检索
+    context_data = retriever.retrieve(intent_result["payload"])
+    
+    print("检索到的上下文:")
+    print(context_data["context_str"])
+    
+    # 5. (可选) 发送给 LLM 生成最终回答
+    # llm.chat(query, context=context_data["context_str"])
+else:
+    print("需澄清:", intent_result["message"])
+```
+
+## ⚙️ 关键配置说明
+
+### IntentGovernor
+*   **默认值注入**: 在 `process` 方法中，针对 `industry` 和 `time_window` 为空的情况做了默认值处理（全市场/最新）。
+*   **指标清洗**: 内置 `_clean_indicator` (内部逻辑) 函数，防止“半导体”同时出现在行业和指标列表中。
+
+### StockRetriever
+*   **search_knowledge**: 调用 VikingDB 的标准接口。
+*   **Limit**: 默认每个指标检索 `TOP_K=1` 条最相关定义（因为使用了强时间约束，召回精度较高）。
+
+## ❓ 常见问题
+
+**Q: 为什么检索结果里还是有“前3月”的数据？**
+A: 请检查 `GoalFrame` 中的 `time_window` 是否被正确提取。如果提取正确，可能需要调整 VikingDB 的 Embedding 模型或增加 Rerank 步骤。
+
+**Q: 离线编译报错 "Reasoning mismatch"？**
+A: 这是因为 LLM 的思维链与生成的 JSON 不一致。请检查 `builder.py` 中的 Labeler Prompt，确保约束条件明确。我们已在最新版中放宽了校验逻辑。
+
+**Q: 如何更新意图识别能力？**
+A: 只需在 CSV 中添加新的典型 Case，重新运行 `builder.py`，然后重启在线服务即可。无需修改 Python 代码。
