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 -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
