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
shellcheckis 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.
Resources

run_shellck.sh: shellcheck runner with sensible defaults and directory filtering.
