description	Create or modify Bash scripts with purpose header, emoji logs, and readable guard-clause flow.

Bash Script Skill

When to use

• New Bash scripts.
• Existing Bash scripts that need updates.

Mandatory rules

• Use Bash (#!/usr/bin/env bash), never POSIX sh.
• Header must include purpose and usage examples.
• Use emoji logs for runtime states.
• Prefer early return and guard clauses.
• Keep logic straightforward and readable.
• Do not add unit tests unless explicitly requested.

Minimal template

#!/usr/bin/env bash
#
# Purpose: {description}
# Usage examples:
#   ./{script_name}.sh --help

set -euo pipefail

log_info() { echo "ℹ️  $*"; }
log_warn() { echo "⚠️  $*"; }
log_success() { echo "✅ $*"; }
log_error() { echo "❌ $*" >&2; }

Validation

• bash -n
• shellcheck -s bash (if available)
