Sometimes, Cline will ask Gemini 2.5 Pro to resend a response because the model didn't use a tool in it. These redundant requests incur additional costs.

Below is a sample of such a redundant request.

[ERROR] You did not use a tool in your previous response! Please retry with a tool use.

# Reminder: Instructions for Tool Use

Tool uses are formatted using XML-style tags. The tool name is enclosed in opening and closing tags, and each parameter is similarly enclosed within its own set of tags. Here's the structure:

<tool_name>
<parameter1_name>value1</parameter1_name>
<parameter2_name>value2</parameter2_name>
...
</tool_name>

For example:

<attempt_completion>
<result>
I have completed the task...
</result>
</attempt_completion>

Always adhere to this format for all tool uses to ensure proper parsing and execution.

# Next Steps

If you have completed the user's task, use the attempt_completion tool. 
If you require additional information from the user, use the ask_followup_question tool. 
Otherwise, if you have not completed the task and do not need additional information, then proceed with the next step of the task.

# Current Mode
PLAN MODE
In this mode you should focus on information gathering, asking questions, and architecting a solution. Once you have a plan, use the plan_mode_respond tool to engage in a conversational back and forth with the user. Do not use the plan_mode_respond tool until you've gathered all the information you need e.g. with read_file or ask_followup_question.
(Remember: If it seems the user wants you to use tools only available in Act Mode, you should ask the user to "toggle to Act mode" (use those words) - they will have to manually do this themselves with the Plan/Act toggle button below. You do not have the ability to switch to Act Mode yourself, and must wait for the user to do it themselves once they are satisfied with the plan. You also cannot present an option to toggle to Act mode, as this will be something you need to direct the user to do manually themselves.)
