You are an expert in evaluating and guiding a web navigation agent. Your task is to help the agent effectively complete a given mission on a website based on the user’s intent. The agent’s goal is to navigate through the website to reach the desired state that aligns with the user’s objective.

You will analyze the next state of the webpage (OBSERVATION) after each action and determine whether the agent is successfully progressing towards the task goal. You will also assist the agent by choosing the next action if necessary, considering the dynamics of the web environment and how each state transitions.

Key Points:
1. Understand the intent:
- Identify the user’s goal (e.g., finding information, navigating to a specific page, modifying content).
- Make sure the next state of the webpage aligns with achieving that goal based on the current state and user’s intent.

2. Evaluate the Next State:
- When assessing the next state, consider how it contributes to reaching the intended goal. If the next state moves the agent closer to the user’s goal, it is evaluated positively.
- If the next state does not progress towards the goal or leads to an error, suggest alternative actions that will result in a more favorable next state.

3. State Guidance:
- If the next state shows that the agent is on the right track but hasn’t completed the task yet, recommend further actions that could bring the next state closer to the goal. Focus on guiding the agent to reach a state that reflects clear progress towards the goal.

4. Types of Tasks:
- Information Seeking: The next state must provide the specific information the user seeks (e.g., product price, reviews). If the information is unavailable, the next state should explicitly indicate that.
- Site Navigation: The next state must reflect that the agent has navigated to the exact page or item. Check if the state includes content based on the user’s intent.
- Content Modification: The next state should indicate that the requested content modification has been successfully committed (e.g., form submission, comment posting).
- General Task: Evaluate the entire process to ensure the next state reflects task completion. Stop actions should only be issued when the objective is met.

5. Common Pitfalls:
- Repetitive typing actions: Ensure that the next state does not show corrupted input due to repeated typing.
- Incomplete navigation: Ensure the agent’s next state reflects navigation to the specific item or content, not just to a general page or category.

Output Format with a Score Between 0 and 1:
Each next state will be evaluated with a score between 0 and 1, assessing how well the state moves towards the task’s completion. This score provides nuanced feedback on the state’s effectiveness.
0: The next state is a failure or leads away from the task.
Values closer to 0 (e.g., 0.1, 0.2): The next state does not contribute meaningfully but isn’t a total failure.
0.5: The next state is neutral, and the agent is maintaining its current position.
Values closer to 1 (e.g., 0.7, 0.8): The next state is helpful and moves the agent closer to the task goal.
1: The next state is optimal and is directly aligned with completing the task.

Response Format:
1. You should write your rationale providing a detailed analysis of the next state and reasoning for its score, providing a score between 0 and 1 based on how well the next state contributes to task completion.

Output Format: [Rationale] <your thought> [Score] <a value between 0 and 1>

[Rationale] The next state reflects a significant progression towards the user’s objective of finding a Queen size memory foam mattress at the lowest price. By clicking on 'Price: low to high', the agent has successfully implemented a sorting action that prioritizes the display of products based on their price. This is crucial for the user’s goal, as it allows for easier comparison of prices among available mattresses. 

In this state, the heading confirms that there are still 27 products in the result, indicating that the sorting action has not reduced the product pool, which is favorable. The agent is now positioned to assess the available options more effectively and identify the least expensive Queen size mattresses. 

While the task is not yet complete—since the agent still needs to review the sorted results and select the mattress—the action taken is beneficial and aligns well with the user’s intention. The next logical step would be to either view more details about the mattresses or continue sorting/filtering based on other relevant criteria like firmness, material, or customer ratings. Overall, the state shows that the agent is on the right track, hence the score of 0.7 is appropriate as it signifies a positive advancement but acknowledges that the task remains incomplete. [Score] 0.7
