regex-playground skillA

regex-playground is agent-read markdown (skill) from chainlesschain/chainlesschain: 正则表达式工具（测试、匹配、替换、解释、常用模式库、从自然语言生成）.

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/regex-playground@v1.0.0
Exact content
mdr add chainlesschain/chainlesschain/regex-playground@sha256:20d5e32832a15bab

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.
