minimax-image-understanding is a Claude skill that calls the MiniMax VLM understand_image tool on screenshots, diagrams, and UI photos when text context is missing or OCR-style extraction is needed.
About
minimax-image-understanding is a Claude Code skill for the MiniMax coding-plan MCP extension that analyzes images via the understand_image tool. Pass a natural-language prompt plus an image_url to describe screenshots, extract error messages, read code from photos, interpret charts, or review UI layouts. Use cases include debugging from error screenshots, OCR on document images, and UX analysis when only a PNG is available. Developers reach for minimax-image-understanding whenever visual context is required and the text transcript alone is incomplete.
- Single understand_image tool: prompt plus image_url (HTTPS or data:image base64)
- POST {api_host}/v1/coding_plan/vlm with JSON prompt and image_url
- Documented use cases: error screenshots, UI/UX review, charts, OCR, visual debugging
- Explicit anti-patterns: skip when image already described, simple icons, inaccessible URLs, or redundant file context

Skip if: Batch image pipelines outside the MiniMax MCP tool or tasks solvable from plain text logs alone.
When should I use this skill?
The user shares a screenshot, diagram, chart, or UI photo and needs description, OCR, or visual debugging via understand_image.
What you get
Structured natural-language analysis of image content including OCR text, UI details, and diagram interpretations.
- image analysis text
- extracted OCR content

MiniMax Image Understanding Skill
Use this skill when you need to analyze, describe, or extract information from images.
How to Use
Call the understand_image tool directly with a prompt and image URL:
understand_image({
prompt: "Your question about the image",
image_url: "https://example.com/image.png"
})When to Use
Use understand_image when:
- Screenshots: Error messages, UI issues, code in screenshots
- Visual content: Photos, diagrams, charts, graphs
- Documents: Extracting text from images (OCR), understanding layouts
- UI/UX analysis: Evaluating designs, identifying components
- Visual debugging: Understanding visual bugs or layout issues
When NOT to Use
Do NOT use understand_image when:
- Image is already described in the conversation
- The image is a simple icon or emoji you recognize
- No image is provided or the image URL is inaccessible
- Redundant with existing context (e.g., file contents already visible)
Usage
understand_image({
prompt: "What do you see in this image?",
image_url: "https://example.com/screenshot.png"
})API Details
Endpoint: POST {api_host}/v1/coding_plan/vlm
Request Body:
{
"prompt": "Your question about the image",
"image_url": "data:image/jpeg;base64,/9j/4AAQ..."
}Response Format:
{
"content": "AI analysis of the image...",
"base_resp": {
"status_code": 0,
"status_msg": "success"
}
}Image Processing
The tool automatically handles three types of image inputs:
1. HTTP/HTTPS URLs: Downloads the image and converts to base64
- Example:
https://example.com/image.jpg
2. Local file paths: Reads local files and converts to base64
- Absolute:
/Users/username/Documents/image.png - Relative:
images/photo.png - Removes
@prefix if present
3. Base64 data URLs: Passes through existing base64 data
- Example:
data:image/png;base64,iVBORw0KGgo...
Image Formats
Supported:
- JPEG (.jpg, .jpeg)
- PNG (.png)
- WebP (.webp)
Not supported:
- PDF, GIF, PSD, SVG, and other formats
Crafting Effective Prompts
For Descriptions
- "Describe what's in this image in detail"
- "What is the main subject of this image?"
- "Describe the visual style and composition"
For Code/Technical
- "What code is shown in this screenshot?"
- "Extract all text from this image"
- "Identify the UI framework/components used"
For Analysis
- "Analyze this UI design. What is working well and what could be improved?"
- "What emotions or mood does this image convey?"
- "Compare this design to Material Design principles"
For OCR/Text Extraction
- "Extract all text from this image"
- "Read the error message in this screenshot"
- "What does the label say in this image?"
Examples
Error Analysis
understand_image({
prompt: "What is the error message and where is it located in this screenshot?",
image_url: "./error-screenshot.png"
})Code Screenshot
understand_image({
prompt: "What code is shown in this screenshot? Please transcribe it exactly.",
image_url: "https://example.com/code.png"
})Design Review
understand_image({
prompt: "Analyze this UI design. What is working well and what could be improved?",
image_url: "https://example.com/mockup.png"
})OCR
understand_image({
prompt: "Extract all text from this image",
image_url: "/Users/username/Documents/scan.png"
})Tips
1. Be specific in your prompt about what you want to know 2. Mention format if you need structured output (e.g., "list all elements") 3. Include context if the image is part of a larger task 4. For screenshots, specify if you need full-page or just a specific area 5. Complex analysis may trigger a confirmation prompt (analyze, extract, describe, recognize, transcribe, read)
Error Handling
- Status code 1004: Authentication error - check API key and region
- Status code 2038: Real-name verification required
- Invalid image: File doesn't exist or URL is inaccessible
- Unsupported format: Image format not in JPEG, PNG, WebP
