shell-scripts skillA

shell-scripts is agent-read markdown (skill) from ahgraber/skills: Use when writing or reviewing Bash scripts and shell snippets, especially for shebang selection, quoting, parameter expansion ("${VAR}" style), test expressions (`[ ]` vs `[[ ]]`), ShellCheck-guided fixes, and portability decisions across POSIX sh, Bash, and zsh compatibility targets..

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 ahgraber/skills/shell-scripts@git:20260819.209d97b
Exact content
mdr add ahgraber/skills/shell-scripts@sha256:5f86227cf165fedd

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.
