Agent skill
lsof
Enhanced lsof interface for viewing open files with TUI support and structured data exports (TSV, CSV). Core Scenario: When the user needs to identify which files are open by which processes, supporting interactive search.

lsof - List Open Files Enhancement
The lsof module provides a more intuitive way to interact with the system's open file list. It supports an interactive TUI for exploration and allows exporting results in common data formats.
When to Activate
- When investigating file locking issues or identifying process ownership of files.
- When performing interactive searches of open files using FZF.
- When exporting open file data to CSV or TSV for script processing.
- When needing thread-level details (
--task) for open files.
Core Principles & Rules
- Interactive TUI: Automatically displays a TUI when connected to a terminal; otherwise, defaults to TSV.
- Data-Centric: Use
--csvor--tsvwhen the output is intended for automation or external analysis. - Searchable: Leverage the
fzsubcommand for fast interactive filtering.
Patterns & Examples
Interactive Search
# Interactively search and view open files via FZF
x lsof fz
Export to CSV
# Output current open files as a CSV for processing
x lsof --csv
View Thread Info
# Display task (thread) IDs and names for open files
x lsof --task
Checklist
- Confirm if the user needs an interactive view or a static data export.
- Verify if thread-level information is required.
- Ensure the correct export format (CSV/TSV) is selected if needed.

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.
