Use this skill when tabular work involves large CSV-like files and shell-oriented data pipelines.

When to Use

CSV/TSV files are large (size or rows) and Python/pandas style processing is too heavy.
You need fast CLI operations such as filter, sort, dedup, groupby, frequency, join.
You want low-memory streaming workflows in terminal pipelines.

Boundaries

Not for workbook semantics (.xlsx formula/layout preservation) — use xlsx or excel-analysis.
Not for ML model training pipelines — use data-ml skills.
This skill is a thin CLI wrapper; it does not implement custom parsing logic itself.
