Structured shell, pipelines, and data transforms from the terminal. Built by Nushell. Supports structured output — good for scripts and agents.

Open CLI packages the install path, verify step, and safe-start workflow so this tool can move from “interesting CLI” to something you can actually use. It also integrates with skills.sh so each CLI comes with the right companion skills, not just a binary and a docs link.

When to apply

  • structured shell, pipelines, and data transforms from the terminal.
  • You want shell utilities you can script with structured output.
  • You need structured shell.
  • You need pipelines.
  • You need data transforms.
