# Image Caption Analysis — 图片描述与数据提取 ## Overview Analyze, extract data from, or understand image files (.png, .jpg, .jpeg, .gif, .webp, .bmp). The core workflow: 1. Run `scripts/caption.py` to get a text description of the image 2. Parse the description into structured data (DataFrame, etc.) 3. Analyze, visualize, or export ## scripts/caption.py — Image Caption The script converts images to text descriptions via a vision model. Configure via `SN_API_KEY` (minimum required), or use `SN_VISION_API_KEY` / `SN_VISION_BASE_URL` / `SN_VISION_MODEL` for fine-grained control. See the project environment variable spec for the full fallback chain. ### Usage ```bash # Basic — get text description python3 scripts/caption.py /mnt/data/image.png # Custom prompt — guide what to extract python3 scripts/caption.py /mnt/data/chart.png --prompt "提取所有数值，Markdown 表格格式" # JSON output — includes detected type, usage stats, cache info python3 scripts/caption.py /mnt/data/image.png --json # Batch — process all images in a directory python3 scripts/caption.py /mnt/data/images/ --batch --output /mnt/data/captions.json # Override model (optional) python3 scripts/caption.py /mnt/data/image.png --model gemini-3

How do I install it?

Run `npx skills add OpenSenseNova/SenseNova-Skills --skill sn-da-image-caption --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From OpenSenseNova/SenseNova-Skills, a repository with 4,855 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
