### response
Final answer to the user.

Use this tool only when the task is done, blocked, or no tool is needed.

Do not use this tool for "proceed", "continue", "go ahead", or similar continuation requests when there is an unfinished next step. Call a real tool instead.

Arguments in `tool_args`:
- `text`: concise final answer text

Example:

`{"tool_name":"response","tool_args":{"text":"There are 24 files in /tmp."}}`
