No nameNote function call found in response. The model faile

Error message

No nameNote function call found in response. The model failed to generate a valid response.

What it means

GenNoteName, in the non-XML path, expects a nameNote function call whose content is JSON for prompts.NoteNameRes. When the response Content is empty — i.e. the model made no nameNote function call — this error is returned, meaning no structured name was produced.

Solutions

1. Retry the request once before failing the operation.
2. Set tool_choice to force the nameNote function.
3. Verify nameNote is registered in the tools list with a valid schema.
4. Raise max_tokens and keep format instructions explicit.
5. Prefer models with reliable native function calling.

Example fix

// before
modelReq{Prompt: prompt, Tools: tools}
// after
modelReq{Prompt: prompt, Tools: tools, ToolChoice: {Type: "function", Function: {Name: "nameNote"}}}

func hasContent(res *shared.ModelRes) bool { return res != nil && res.Content != "" }

name, err := model.GenNoteName(ctx, req)
if err != nil {
    if strings.Contains(err.Error(), "No nameNote function call found") {
        name, err = model.GenNoteName(ctx, req) // one retry
    }
    if err != nil { return fmt.Errorf("note naming failed: %w", err) }
}

When it happens

Trigger: PreferredOutputFormat != XML and the LLM response lacks a nameNote function call: plain-text answer, refusal, missing/misconfigured tools, or provider silently dropping tool_call fields.

Common situations: Switching to models with weaker function calling, API version drift changing tool_call shape, prompts encouraging direct answers, or token truncation before the tool call.
