scripting-cli-automation

Writing small scripts and command-line tools to automate repeatable tasks in Node and TypeScript (default) or shell - when to script versus do by hand, idempotent and safe-by-default behaviour (dry-run, confirmation for destructive actions), argument parsing, exit codes, stdout versus stderr, machine-readable JSON output, logging verbosity, config and environment variables, keeping secrets out of arguments, cross-platform paths, shell safety (quoting, strict mode, avoiding eval), testing scripts, usage via --help, script locations and pnpm package scripts, scheduled runs with failure alerts, and keeping scripts small and boring. Load when automating a repeated task, adding a script or CLI to a project, or reviewing a script for safety.
