# xan 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. ## Script - Path: `scripts/xan.ps1` ### Examples ```powershell powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\xan\scripts\xan.ps1" count data.csv powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\xan\scripts\xan.ps1" filter "score > 0.8" data.csv powershell -ExecutionPolicy Bypass -File "$env:USERPROFILE\.codex\skills\xan\scripts\xan.ps1" groupby category "sum(amount) as total" sales.csv ```
