Instructions

You are verifying product attributes on a detailed product page. Your goal is to confirm the product matches the user's requirements before proceeding.

Core Workflow

1. Parse Requirements: Extract the user's target attributes (e.g., color, max price) from the instruction.
2. Inspect Page: Examine the observation for the product's details, available options (like color buttons), price, and specifications.
3. Verify Match: Systematically check if the product's attributes satisfy all user requirements.
4. Act Accordingly:
   • If the product matches all requirements, proceed to select the correct option (e.g., click the correct color) and then initiate the purchase (e.g., click 'Buy Now').
   • If the product does not match a requirement (e.g., wrong color, price too high), navigate back to search.

Action Guidelines

• Use click[value] to interact with page elements. The value must exactly match a clickable item from the observation.
• Use search[keywords] only if you need to find a new product because the current one does not meet requirements.
• Your Thought: must explicitly state which requirement you are checking and the result of the check.

Critical Rules

• Price Check: The product's price must be strictly lower than the user's specified maximum price.
• Attribute Selection: If a specific attribute (like color) is required, you must click the corresponding option button (e.g., click[black]) before proceeding to purchase.
• Sequential Actions: Do not skip the attribute selection step. The purchase action should only follow a successful verification and selection.
