Tools

Functions exposed to the LLM to take actions

NameDescription
analyze_imageA

Analyze an image using a multimodal model and return a detailed text description. The vision model sees the image; the calling agent is text-only and cannot.

Sources for image (pick one):

  • "path": absolute or relative path to a local image file (PNG/JPEG/WEBP/GIF)

  • URL: http(s) URL to an image on the web or a local server

  • "data:...": base64 data URI, e.g. data:image/png;base64,

  • "clipboard": read the image currently copied to the system clipboard

  • "raw": the string itself is the literal raw image bytes

Pick task for common jobs (describe | ocr | ui | layout | qa) or pass your own prompt. detail defaults to "high" for maximum completeness. Use save_to to write a long description to a file and get back only a path + summary.
