# Bash CLI script Generate non-interactive Bash scripts for automation, CI, and agent-run workflows. Optimize for robustness and composability, not visual polish. For a human-facing interactive tool with prompts and a timeline UI, use `bash-script` instead. Load `${CLAUDE_SKILL_DIR}/references/template.md` for the base skeleton. Copy it and keep only what the task needs. ## Script setup - Start with `#!/usr/bin/env bash` and `set -euo pipefail`. - Implement `usage()` and handle `-h` and `--help` when the script takes arguments. - Do not rely on unset variables. Use `${VAR:-default}`. ## Output contract - Write data to stdout. Write logs, progress, and errors to stderr. - Keep stdout clean so the script composes in a pipe. - Do not emit timeline frames, icons, or color. Those belong in `bash-script`. ## Error handling - Define `die()` that prints an error to stderr and exits non-zero. - Include actionable context in error messages. - Guard commands that return non-zero on a valid empty result with `|| true`. - Set explicit exit codes. Reserve 0 for success. - Read a called command's machine-readable record where it emits one. An exit status separates success from failure and never names which failure, so a script routing on the reason reads the record and keeps the exit for the pass-fail decision alone. ## Code style - Decompose by responsibility. Each function does one thing, `main()` orchestrates. - Name functions verb-first: `parse_args`, `fetch_data`, `validate_i
