[SYSTEM NOTICE] By the way, you have executed the same tool web_search_tavily 3 times consecutively. Double-check whether another tool, different arguments, or a summary would move the task forward better.

Hi @hxy310! I'm Dosu and I’m helping the AstrBot team.

这个问题有两个层面的原因：

1. LLM 返回了空参数 {}

从日志可以看到 使用工具：web_search_tavily，参数：{}，说明 LLM 在调用 web_search_tavily 时没有传递 query 参数。虽然工具的 JSON schema 中已正确声明 "required": ["query"] [1]，但某些 LLM 仍可能返回空参数。

2. Runner 缺少必填参数校验

tool_loop_agent_runner.py 中的参数处理逻辑只做了过滤（移除不期望的参数），但没有校验必填参数是否存在 [2]。空参数 {} 直接传给了工具的 call 方法，导致 kwargs["query"] 抛出 KeyError [3]。错误信息 error: 'query' 被反馈给 LLM，但 LLM 仍然重复发起相同的空参数调用，形成死循环直到达到 max_step 上限。

这与 #7387 报告的 agent 工具调用循环问题类似 [4]。

建议的修复方向：

1. 在 tool_loop_agent_runner.py 参数过滤之后、工具执行之前，增加对 required 参数的校验，缺失时返回明确的错误提示（如 "Missing required parameters: ['query']"），而非让工具抛出 KeyError
2. 工具实现侧也可加防御性检查，对 query 缺失时返回友好错误而非直接崩溃
3. 增强重复错误检测——连续 N 次相同工具返回相同错误时主动终止循环，而非等到 max_step

To reply, just mention @dosu.
