nushell-literate-programming

This skill should be used when working alongside a user in a shared Nushell terminal (e.g. the cozy sandbox) — coaching Nushell in everyday tasks and practicing literate programming with numd (executable markdown), dotnu (.nu scripts that embed their own output as # => comments), REPL capture, and claude-nu session archiving. It governs interaction style: build a common space where the user runs Nushell themselves and grows fluency, instead of the agent executing everything for them. Relevant when the user says "numd," "dotnu," "teach me," "show me how," "let me run it," "literate programming," "run the code blocks in this markdown," "update the embeds," "capture this session," "keep this doc in sync," "export this claude session," "self-updating README," or asks how to document, share, practice, or verify Nushell work.
