scgpt
by HughYau
Embed and annotate single-cell expression data with scGPT, a foundation model for single-cell biology. Use this skill when: (1) Producing cell embeddings from an AnnData for clustering/integration, (2) Zero-shot or fine-tuned cell-type annotation, (3) Gene-level representation for perturbation/GRN tasks. For probabilistic single-cell models (scVI etc.), use the scvi-tools library.
qrcoin

canvas
by markdown-viewer
Create spatial node-based diagrams with free positioning. Best for mind maps, knowledge graphs, concept maps, and planning boards where precise spatial layout matters. Use JSON format with x/y coordinates. NOT for sequential flows (use mermaid) or data charts (use vega).
data-analytics
by markdown-viewer
Create data analytics and data pipeline diagrams using PlantUML syntax with analytics/database stencil icons. Best for ETL pipelines, data lakes, real-time streaming, data warehousing, and BI dashboards. NOT for simple flowcharts (use mermaid) or general cloud infra (use cloud skill).
vega
