A developer uses it when they need web-embeddable or dashboard-style figures rather than static publication plots.14installs193PolarsThis skill teaches an agent to use Polars, a Python DataFrame library built on Apache Arrow, for fast in-memory data processing. It covers the expression-based API, lazy vs eager evaluation, filtering, group-by and window functions, joins, and I/O across CSV, Parquet, JSON, and databases. Developers use it as a faster pandas replacement for datasets that fit in RAM and for building ETL pipelines.14installs194Protein StructureThis skill directs an agent through structural-biology analysis of proteins: retrieving or predicting 3D structures, assessing quality (resolution, pLDDT/PAE), identifying binding sites, running molecular docking, and comparing structures via alignment. It names databases (PDB, AlphaFold DB, UniProt) and tools (AutoDock Vina, PyMOL, ChimeraX). Researchers use it when working with PDB files, protein folding, or binding-site analysis.14installs195Pubmed DatabaseThis skill guides an agent to search PubMed and MEDLINE literature using advanced Boolean operators, MeSH terms, and field tags, and to access data programmatically through the NCBI E-utilities REST API. It documents ESearch, EFetch, and related endpoints, batch processing, and rate limits. Researchers use it for systematic reviews, meta-analyses, and automated literature workflows.14installs196Rdkit ChemistryThis skill teaches an agent molecular chemistry with RDKit: parsing and validating SMILES, computing descriptors (MW, LogP, TPSA, HBD/HBA), running substructure searches, generating Morgan and MACCS fingerprints with Tanimoto/Dice similarity, applying the Lipinski Rule of Five, and rendering 2D structures. Cheminformatics developers use it for molecular property analysis and similarity screening.14installs197Reactome DatabaseThis skill guides an agent to query the Reactome pathway database via its REST API and the reactome2py Python client for systems-biology analysis. It covers retrieving pathway data from the Content Service, running overrepresentation and expression-data enrichment via the Analysis Service, mapping genes to pathways, and visualizing results. Researchers use it for pathway enrichment on gene or protein lists.14installs198Scanpy SinglecellScanpy-singlecell is a skill for single-cell RNA-seq analysis using the scanpy and anndata Python libraries. It guides preprocessing and QC, clustering and cell-type annotation, differential expression, trajectory inference, and UMAP/tSNE visualization. A developer uses it when analyzing scRNA-seq datasets and following scanpy best practices.14installs199SongseeThis skill drives the songsee command-line tool to generate spectrograms and feature-panel visualizations from audio files. A developer uses it to render a spectrogram, produce a multi-panel grid of audio features like mel, chroma, MFCC, and tempogram, or extract a time slice of a track. It documents the CLI flags for visualization types, palettes, output size, FFT settings, frequency range, and format.14installs200TrelloThis skill manages Trello boards, lists, and cards through the Trello REST API. A developer uses it to list boards and lists, list or create cards, move cards between lists, add comments, or archive cards directly from the command line with curl and jq. It documents API key and token setup and the Trello rate limits.14installs
