This skill should be used when writing or transforming Nushell records (key-value structures) or tables — including `$env` manipulation, record literals, column projection with `select`/`reject`, building records from iterables, or any time keys/values/columns are being added, removed, filtered, or restructured. Trigger phrases: "record", "table", "key/value", "select column", "build a record", "filter columns", "transform $env".

From the source SKILL.md

Records are nu's primary data structure. A record is {key: value, …}. A table is a list of records that all share the same column shape — [[a b]; [1 2] [3 4]] is a table with two columns a and b and two rows. The distinction matters because some operations are record-shaped and some are table-shaped, and converting between the two is one of the most common operations.

What this skill does

Nushell Records is a community-contributed Claude Code skill in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/nushell-records/ and loads when your prompt matches the skill's trigger.
