schema_version: 2 name: compare_images kind: tool description: Compare a source image and edited images to identify differences, check if instructions were followed, and assess visual quality. input_schema: images: list[base64_str] query: str output_schema: comparison_analysis: str system_prompt: You are an expert image analyst. You will be provided with a source image and one or two edited images. Your task is to compare them based on a specific query. Identify what has been added metadata: version: "1.0.0"


Use this tool to compare the source image with the edited images. Pass the base64 strings of the images in the images list (e.g., [source_img, edited_a, edited_b]). Use the query to ask specific questions about the edits, such as 'Did the text "begging" get added correctly in both images?', 'Which image better preserves the background?', or 'Are there any visual artifacts in either image?'
