Shellck

Overview

Provide a fast, repeatable shellcheck pass for repo scripts. Use this skill after editing shell scripts or when a script fails unexpectedly.

Workflow

Ensure shellcheck is installed.
From the repo root, run the helper script.

Quick start

Run against the default scripts/ directory:

$CODEX_HOME/skills/shellck/scripts/run_shellck.sh

Run against specific files or directories:

$CODEX_HOME/skills/shellck/scripts/run_shellck.sh scripts/perf-profiler
$CODEX_HOME/skills/shellck/scripts/run_shellck.sh scripts/ other/dir/some.sh

Behavior

If no paths are provided, it scans scripts/ for shell scripts.
If paths are provided, it accepts files or directories and filters to shell scripts by extension or shebang.
Exits non-zero on shellcheck failures.
