   Do you use LiteLLM by any chance?

   This happens to me every time compaction happens (automatically by reaching limit or manually).
   Only using LiteLLM

   I don't think that _noop tool call is healthy for the context data and this tool is injected only for LiteLLM-like providers.

    Using the latest opencode with Qwen3.5-122B-a10b model on latest LM Studio, I have the same issue any time I run /compact. After that I can't use the session any more, I get the error message below.

    "Error rendering prompt with jinja template: "No user query found in messages.".\n\nThis is usually an issue with the model's prompt template. If you are using a popular model, you can try to search the model under lmstudio-community, which will have fixed prompt templates. If you cannot find one, you are welcome to post this issue to our discord or issue tracker on GitHub. Alternatively, if you know how to write jinja templates, you can override the prompt template in My Models > model settings > Prompt Template."
