Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| inspect_pageA | Inspect a webpage's structure, metadata, and content. Use for understanding what's on a page without visual analysis. Basic mode uses static fetch (fast, no browser). Full mode uses headless browser for DOM/accessibility/element extraction. Does NOT invoke the vision model. |
| analyze_imageA | Analyze one or more local image files using MiniMax vision. No browser involved. Use for screenshots, mockups, design files, or any image. Supports PNG, JPEG, GIF, WebP, BMP. |
| analyze_page_visualA | Analyze a webpage visually using screenshot + DOM structure + MiniMax vision. Use for design critique, UX review, visual hierarchy, layout analysis, UI bugs, and above-the-fold analysis. Defaults to viewport screenshot. Returns structured findings with element refs and evidence. |
| extract_page_dataA | Extract structured data from a webpage matching a provided schema. DOM-first: uses static extraction first, escalates to headless browser then MiniMax vision only if needed. Use for pricing tiers, product info, contact details, speaker lists, tables, API docs, or any structured content. |
