+  Analyze, describe, and extract information from images using the MiniMax vision MCP tool.
+  Use when: user shares an image file path or URL (any message containing .jpg, .jpeg, .png,
+  .gif, .webp, .bmp, or .svg file extension) or uses any of these words/phrases near an image:
+  "analyze", "analyse", "describe", "explain", "understand", "look at", "review",
+  "extract text", "OCR", "what is in", "what's in", "read this image", "see this image",
+  "tell me about", "explain this", "interpret this", in connection with an image, screenshot,
+  diagram, chart, mockup, wireframe, or photo.
+  Also triggers for: UI mockup review, wireframe analysis, design critique, data extraction
+  from charts, object detection, person/animal/activity identification.
+  Triggers: any message with an image file extension (jpg, jpeg, png, gif, webp, bmp, svg),
+  or any request to analyze/describ/understand/review/extract text from an image, screenshot,
+  diagram, chart, photo, mockup, or wireframe.

+
+# Vision Analysis
+
+Analyze images using the MiniMax `MiniMax_understand_image` MCP tool available in the MiniMax Token Plan.
+
+## Prerequisites
+
+- MiniMax Token Plan subscription with valid `MINIMAX_API_KEY`
+- MiniMax MCP configured in OpenCode (`MiniMax_understand_image` tool available)
+
+## Analysis Modes
+
+| Mode | When to use | Prompt strategy |
+|---|---|---|
+| `describe` | General image understanding | Ask for detailed description |
+| `ocr` | Text extraction from screenshots, documents | Ask to extract all text verbatim |
+| `ui-review` | UI mockups, wireframes, design files | Ask for design critique with suggestions |
+| `chart-data` | Charts, graphs, data visualizations | Ask to extract data points and trends |
+| `object-detect` | Identify objects, people, activities | Ask to list and locate all elements |
+
+## Workflow
+
+### Step 1: Auto-detect image
+
+The skill triggers automatically when a message contains an image file path or URL with extensions:
+`.jpg`, `.jpeg`, `.png`, `.gif`, `.webp`, `.bmp`, `.svg`
+
+Extract the image path from the message.
+
+### Step 2: Select analysis mode and call MCP tool
+
+Use the `MiniMax_understand_image` tool with a mode-specific prompt:
+
+**describe:**
+```
+Provide a detailed description of this image. Include: main subject, setting/background,
+colors/style, any text visible, notable objects, and overall composition.
+```
+
+**ocr:**
+```
+Extract all text visible in this image verbatim. Preserve structure and formatting
+(headers, lists, columns). If no text is found, say so.
+```
+
+**ui-review:**
+```
+You are a UI/UX design reviewer. Analyze this interface mockup or design. Provide:
+(1) Strengths — what works well, (2) Issues — usability or design problems,
+(3) Specific, actionable suggestions for improvement. Be constructive and detailed.
+```
+
+**chart-data:**
+```
+Extract all data from this chart or graph. List: chart title, axis labels, all
+data points/series with values if readable, and a brief summary of the trend.
+```
+
+**object-detect:**
+```
+List all distinct objects, people, and activities you can identify. For each,
+describe what it is and its approximate location in the image.
+```
+
+### Step 3: Present results
+
+Return the analysis clearly. For `describe`, use readable prose. For `ocr`, preserve structure. For `ui-review`, use a structured critique format.
+
+## Output Format Example
+
+For describe mode:
+```
+## Image Description
+
+[Detailed description of the image contents...]
+```
+
+For ocr mode:
+```
+## Extracted Text
+
+[Preserved text structure from the image]
+```
+
+For ui-review mode:
+```
+## UI Design Review
+
+### Strengths
+- ...
+
+### Issues
+- ...
+
+### Suggestions
+- ...
+```
+
+## Notes
+
+- Images up to 20MB supported (JPEG, PNG, GIF, WebP)
+- Local file paths work if MiniMax MCP is configured with file access
+- The `MiniMax_understand_image` tool is provided by the `minimax-coding-plan-mcp` package
