free-vision-skill

Fully-local image understanding (OCR / table extraction / description) via macOS Vision. Images never leave your Mac.

Install (DSH-Plugin)

dsh plugin add @niyongsheng/free-vision-skill

Then add to cordis.patch.yml:

- insert:
    - id: free-vision-skill
      name: '@niyongsheng/free-vision-skill'
      config:
        timeout: 120000

Tools

• view_image — describe image content (scene, people, QR, composition)
• ocr_image — extract text; layout=true for table structure + coordinates

Input: http(s) URL / base64 / local path.

Paste-to-path (Web UI)

Paste (⌘V) an image in the DSH web input box → its local absolute path is inserted. Loopback-only upload, magic-byte checked: PNG / JPEG / GIF / WebP / HEIC / HEIF.

Usage (Claude Code Skill)

swift scripts/ocr.swift image.png          # OCR
swift scripts/ocr.swift --layout image.png # table + coordinates
swift scripts/ocr.swift --describe image.png # describe image

Notes

• Requires macOS 11+ & Xcode Command Line Tools
• First run compiles ~5–10s, cached afterwards
