cli-anything: wrap any CLI into an agent skill

Turn any command-line tool into something an AI agent can call reliably and parse. The output is a thin, well-documented wrapper contract — never a reimplementation of the tool. Use the real tool; document how to drive it.

When to use

You have a CLI (your own, or a third-party binary) and you want an agent to invoke it predictably, read structured results, and recover from errors. This skill produces a SKILL.md wrapper that encodes that contract.

Step 1 — Introspect the CLI (do not guess)

Enumerate the real surface before writing anything:

• Run <tool> --help and <tool> <subcommand> --help for each subcommand.
• Capture: subcommands, flags (required vs optional), positional args, exit codes, and the output format (human text vs structured).
• If --help is thin, read the source or man page. Every claim in the wrapper must trace to observed behavior.

Step 2 — Define the output contract
