regex skillA

regex is agent-read markdown (skill) from bug-ops/zeph: Write, test, and debug regular expressions for pattern matching, search, and text extraction across programming languages. Use when the user asks to match patterns in text, validate input formats (email, URL, IP, phone, date), extract data with capture groups, build search patterns with lookahead or lookbehind, or understand regex syntax differences between PCRE, POSIX, JavaScript, Python, and Rust flavors..

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 bug-ops/zeph/regex@v1.0
Exact content
mdr add bug-ops/zeph/regex@sha256:291c2584687c3a44

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.
