The agent demonstrates a strong capability in retrieving detailed astronomical data, as evidenced by the accurate and comprehensive response regarding the positions and properties of celestial bodies. However, the agent struggles with generating visual outputs such as Moon phase images and star charts, often due to tool malfunctions or input issues. These limitations significantly impact the agent's overall performance, as it fails to deliver on several key functionalities. The agent's ability to handle input specifications and manage tool limitations needs improvement to enhance its reliability and effectiveness.

Score: 6/10
Perform the operation of generating a Moon phase image for July 31, 2025.
No valid answer is generated due to invalid input. The attempt to generate a Moon phase image for July 31, 2025, failed because the request was incomplete. To successfully generate the image, we need to specify: - The observer's location (latitude and longitude) - The view type (portrait or landscape) - The style settings for the image. If you can provide these details, I can attempt to generate the Moon phase image again.

Perform the operation of generating a star chart for Los Angeles, California, on July 31, 2025, at 10:00 PM local time.
No valid answer is generated due to tool malfunction. The response indicates persistent issues with the star chart generation tool, specifically with the parameters being rejected due to unexpected keyword arguments. This suggests that the tool's expected input structure is not aligning with what was provided, preventing the generation of the star chart.
