Out-of-core DataFrame for billion-row data via lazy evaluation and memory-mapped files. Use when data exceeds RAM (10 GB–TB) for fast aggregation, filtering, virtual columns, and visualization without loading. Supports HDF5, Arrow, Parquet, CSV with cloud (S3, GCS, Azure). Built-in ML transformers (scaling, PCA, K-means). In-memory: polars; distributed: dask.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'vaex-dataframes' ] || [ -L ~/.agents/skills/'vaex-dataframes' ]; then echo 'A skill folder named vaex-dataframes already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jaechang-hits/SciAgent-Skills' "$d" && git -C "$d" checkout --quiet '65d6ceb875e20b751ffb3a6d8ee19516558789e1' -- 'skills/scientific-computing/vaex-dataframes' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/scientific-computing/vaex-dataframes' ~/.agents/skills/'vaex-dataframes' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'vaex-dataframes' ~/.claude/skills/'vaex-dataframes' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
