name: shellck
description: Run shellcheck on shell scripts after editing scripts or when debugging shell errors. Use for linting scripts in a repo (especially scripts/), catching issues like set -u with unset vars, bad subshell usage, or quoting mistakes.

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

1) Ensure shellcheck is installed.
2) 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.
