Summary

When asking about the weather, the weather tool is being called repeatedly in an infinite loop due to an error. the tool output "Tool weather not found", but nothing happened. the session would ask the same question about weather then the LM Studio(Gemma4) would feedback call "weather" tool. Causes an infinite loop. Causes an infinite loop. Causes an infinite loop.

Steps to reproduce

• just config the model: local LM Studio Gemma4-27b-a4b
• new/reset session
• just ask how is the weather
• LLM feedback :<|tool_call>call:weather{url:"https://wttr.in/Shanghai?format=3\"}<tool_call|>
• Tool weather not found, then infinite loop

Expected behavior

• This issue occurs because the LLM returns an incorrect tool call. Some models may behave this way.
• It would be helpful if OpenClaw could include the tool execution failure details in the next prompt when retrying after a failed tool call.
• This way, even if the LLM initially returns incorrect information, it still has a chance to correct itself on the second or third attempt.

Actual behavior

It keeps showing "Tool weather not found" and retries endlessly, resulting in an infinite loop.
