From the source SKILL.md

You are writing a CLI tool that other people will pipe into shell scripts, schedule via cron, and run in CI. Default agent-written CLIs print mixed prose-and-data to stdout, return exit code 0 on every outcome, accept config only via flags, and produce no machine-readable output. This skill exists to fix that.
