Use @shellcheck-configuration to lint bash script

Phase 7: Documentation

Skills to Invoke

• documentation-templates - Documentation

Actions

1. Add script header
2. Document functions
3. Create usage examples
4. List dependencies
5. Add troubleshooting section

Copy-Paste Prompts

Use @documentation-templates to document bash script

Script Template

#!/usr/bin/env bash
set -euo pipefail

readonly SCRIPT_NAME=$(basename "$0")
readonly SCRIPT_DIR=$(cd "$(dirname "$0")" && pwd)

log() { echo "[$(date '+%Y-%m-%d %H:%M:%S')] $*"; }
error() { log "ERROR: $*" >&2; exit 1; }

usage() { cat <<EOF
Usage: $SCRIPT_NAME [OPTIONS]
Options:
    -h, --help      Show help
    -v, --verbose   Verbose output
EOF
}

main() {
    log "Script started"
    # Implementation
    log "Script completed"
}

main "$@"

Quality Gates

• ShellCheck passes
• Bats tests pass
• Error handling works
• Logging functional
• Documentation complete

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
