pkgx - Universal Tool Runner
The pkgx module provides an interface for the pkgx tool runner, enabling users to fetch and run any open-source utility on-the-fly. It solves the "versioning" and "immediate availability" problems for developers.
When to Activate
- When the user wants to run a tool once without installing it globally.
- When testing a specific version of a software (e.g.,
bun@1.0). - When adding temporary tools to the current execution environment.
Core Principles & Rules
- Non-Invasive: Runs tools without modifying the system's PATH or global configuration.
- Immediate Execution: Use
+pkgto temporarily inject a tool into the environment for a specific command. - Zero-Setup: Automatically handles tool acquisition and execution.
Patterns & Examples
Run Without Installation
# Execute bun without installing it to the system
x pkgx bun --eval 'console.log("hello world")'
Temporary Environment Injection
# Temporarily add fzf to the current environment to run a command
eval "$(x pkgx +fzf)"
Interactive Browsing
# Browse all available packages in the pkgx ecosystem
x pkgx ls
Checklist
- Confirm if the tool is for one-off use or permanent installation.
- Verify if a specific version of the tool is required.
- Ensure the user is aware that the environment is not permanently modified.

pufferlib
High-performance reinforcement learning framework optimized for speed and scale. Use when you need fast parallel training, vectorized environments, multi-agent systems, or integration with game environments (Atari, Procgen, NetHack). Achieves 2-10x speedups over standard implementations. For quick prototyping or standard algorithm implementations with extensive documentation, use stable-baselines3 instead.
fluidsim
Framework for computational fluid dynamics simulations using Python. Use when running fluid dynamics simulations including Navier-Stokes equations (2D/3D), shallow water equations, stratified flows, or when analyzing turbulence, vortex dynamics, or geophysical flows. Provides pseudospectral methods with FFT, HPC support, and comprehensive output analysis.
metabolomics-workbench-database
Access NIH Metabolomics Workbench via REST API (4,200+ studies). Query metabolites, RefMet nomenclature, MS/NMR data, m/z searches, study metadata, for metabolomics and biomarker discovery.
geniml
This skill should be used when working with genomic interval data (BED files) for machine learning tasks. Use for training region embeddings (Region2Vec, BEDspace), single-cell ATAC-seq analysis (scEmbed), building consensus peaks (universes), or any ML-based analysis of genomic regions. Applies to BED file collections, scATAC-seq data, chromatin accessibility datasets, and region-based genomic feature learning.
zinc-database
Access ZINC (230M+ purchasable compounds). Search by ZINC ID/SMILES, similarity searches, 3D-ready structures for docking, analog discovery, for virtual screening and drug discovery.
astropy
Comprehensive Python library for astronomy and astrophysics. This skill should be used when working with astronomical data including celestial coordinates, physical units, FITS files, cosmological calculations, time systems, tables, world coordinate systems (WCS), and astronomical data analysis. Use when tasks involve coordinate transformations, unit conversions, FITS file manipulation, cosmological distance calculations, time scale conversions, or astronomical data processing.
