scvi-tools

scvi-tools is a skill for Claude Code, Codex from Lord1Egypt/scientific-agent-toolkit. It costs 65 tokens per session (1,681 once invoked), scanned A, a copy of scvi-tools, MIT.

A Python toolkit for probabilistic models of single-cell biology data, such as gene activity measured in individual cells. It models uncertainty while correcting batch differences and combining different measurement types.

In plain words
What is it for?
Use it for single-cell RNA sequencing, chromatin-accessibility, spatial transcriptomics, cell-type annotation, differential expression, and transfer learning.
Why use it?
It helps analyse complex single-cell datasets when samples were collected in batches or contain several biological data types.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

scvi-tools scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

scvi-tools

Overview

scvi-tools is a comprehensive Python framework for probabilistic models in single-cell genomics. Built on PyTorch and PyTorch Lightning, it provides deep generative models using variational inference for analyzing diverse single-cell data modalities.

When to Use This Skill

Use this skill when:

  • Analyzing single-cell RNA-seq data (dimensionality reduction, batch correction, integration)
  • Working with single-cell ATAC-seq or chromatin accessibility data
  • Integrating multimodal data (CITE-seq, multiome, paired/unpaired datasets)
  • Analyzing spatial transcriptomics data (deconvolution, spatial mapping)
  • Performing differential expression analysis on single-cell data
  • Conducting cell type annotation or transfer learning tasks
  • Working with specialized single-cell modalities (methylation, cytometry, RNA velocity)
  • Building custom probabilistic models for single-cell analysis

Core Capabilities

scvi-tools provides models organized by data modality:

1. Single-Cell RNA-seq Analysis

Core models for expression analysis, batch correction, and integration. See references/models-scrna-seq.md for:

  • scVI: Unsupervised dimensionality reduction and batch correction
  • scANVI: Semi-supervised cell type annotation and integration
  • AUTOZI: Zero-inflation detection and modeling
  • VeloVI: RNA velocity analysis
  • contrastiveVI: Perturbation effect isolation

2. Chromatin Accessibility (ATAC-seq)

Models for analyzing single-cell chromatin data. See references/models-atac-seq.md for:

  • PeakVI: Peak-based ATAC-seq analysis and integration
  • PoissonVI: Quantitative fragment count modeling
  • scBasset: Deep learning approach with motif analysis

3. Multimodal & Multi-omics Integration

Joint analysis of multiple data types. See references/models-multimodal.md for:

  • totalVI: CITE-seq protein and RNA joint modeling
  • MultiVI: Paired and unpaired multi-omic integration
  • MrVI: Multi-resolution cross-sample analysis

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
