ocr-scanner skillA

ocr-scanner is agent-read markdown (skill) from chainlesschain/chainlesschain: OCR文字识别（图片/PDF文字提取、多语言、批量识别、表格识别）.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add chainlesschain/chainlesschain/ocr-scanner@v1.0.0
Exact content
mdr add chainlesschain/chainlesschain/ocr-scanner@sha256:0ee355444c7800f8

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
