What it does

Xan is an agent skill from foryourhealth111-pixel/Vibe-Skills. High-performance CSV processing with xan CLI for large tabular datasets, streaming transformations, and low-memory pipelines.

Its SKILL.md is about 310 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts.

It sits in Documents & Office, covering CSV and tabular files. It works with Microsoft Excel. The repository describes itself as: Intelligent Skill routing and workflow orchestration for AI agents — +21.12 pp reward, −29.6% tokens on SkillsBench with DeepSeekV4Flash-VE. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve CSV and tabular files

Example prompts

  • “/xan”

Requirements

  • PowerShell

What it can do on your machine

Read from SKILL.md and the folder at commit ddcaa2a. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (PowerShell), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Xan loads about 312 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 93 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~312

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

High-performance CSV processing with xan CLI for large tabular datasets, streaming transformations, and low-memory pipelines.

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
