Skill for building agent-native CLIs

I’ve been building agent-native CLIs for my own workflows and decided to turn what I learned into a reusable skill that might be useful for others. The main idea: As agents move from “API wrappers” to running inside ephemeral sandboxes, CLIs become a really useful interface. But they need to be designed differently. A good CLI for agents should be: * predictable * scriptable * easy to parse * safe by default * non-blocking * clear when something fails The skill covers things like: * `--json` output for agents * `--plain` output for scripts * stdout/stderr separation * avoiding blocking prompts * useful exit codes * actionable errors and hints * command design patterns link in the comment
