file-compressor skillA

file-compressor is agent-read markdown (skill) from chainlesschain/chainlesschain: 文件压缩解压（ZIP创建/解压、目录压缩、文件列表、大小分析）.

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/file-compressor@v1.0.0
Exact content
mdr add chainlesschain/chainlesschain/file-compressor@sha256:8732d3f35a8c3eac

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.
