Evaluate Diagram

Evaluate a generated diagram against a human reference using PaperBanana's VLM-as-Judge scoring.

Instructions

1. $ARGUMENTS[0] is the path to the generated image.
2. $ARGUMENTS[1] is the path to the human reference image.
3. Ask the user for:
   • Source context: the methodology text (or a file path to read it from). If the user provides a file path, read that file to get the text.
   • Figure caption: a description of what the diagram communicates.
4. Call the MCP tool evaluate_diagram with:
   • generated_path: the generated image path
   • reference_path: the reference image path
   • context: the methodology text content
   • caption: the figure caption
5. Present the evaluation scores to the user. Scores cover 4 dimensions: Faithfulness, Conciseness, Readability, and Aesthetics.

CLI Fallback

If the MCP tool is not available, fall back to the CLI:

paperbanana evaluate --generated <generated-img> --reference <reference-img> --context <context-file> --caption "<caption>"
