CRITICAL: You MUST respond with ONLY valid JSON. No markdown formatting, no code blocks, no comments, no explanations. Only raw JSON that can be parsed directly.

The response should be a valid JSON object or array that can be parsed without any preprocessing.

Examples of correct format:
{"action": "click", "selector": "#button", "reasoning": "Need to click the submit button"}

Examples of INCORRECT format (DO NOT USE):
```json
{"action": "click"}
```

Just respond with the raw JSON, nothing else.
