scanpy-sc-analyzer

scanpy-sc-analyzer is a skill for Claude Code, Codex from YuliaNuzhnenko/bioinformatics-agent-skills. It costs 34 tokens per session (550 once invoked), scanned A, original, MIT.

A single-cell RNA sequencing analysis workflow for checking data quality, correcting differences between batches, grouping similar cells, plotting them, and identifying marker genes.

In plain words
What is it for?
Use it to analyze Scanpy-compatible `.h5ad` data, create UMAP plots, form Leiden cell clusters, and annotate clusters using marker genes.
Why use it?
It organizes several analysis steps that would otherwise need to be configured and run separately. It helps reveal unreliable cells, batch-related distortions, and likely cell 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

scanpy-sc-analyzer 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 1mo 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.

Agent Skill: Single-Cell RNA-Seq & Harmony Integration Skill

Domain Version

📌 Description

Autonomous single-cell RNA-seq quality control filtering, Harmony batch-effect correction, Leiden clustering, UMAP visualization, and marker gene annotation.


🤖 Agent Execution Protocol

When an AI Agent is tasked with scanpy-sc-analyzer:

  1. Input Validation: Verify that the required input files or coordinates are supplied.
  2. Environment Check: Ensure dependencies (Scanpy, Harmony, AnnData, Plotly) are installed.
  3. Execution: Run the protocol pipeline snippet below.
  4. Output Generation: Produce actionable Markdown/JSON summaries with publication figures.

💻 Protocol Code Snippet

import scanpy as sc
import numpy as np

def run_sc_pipeline(h5ad_path):
    adata = sc.read_h5ad(h5ad_path)
    sc.pp.filter_cells(adata, min_genes=200)
    sc.pp.filter_genes(adata, min_cells=3)
    sc.pp.normalize_total(adata, target_sum=1e4)
    sc.pp.log1p(adata)
    sc.pp.highly_variable_genes(adata, n_top_genes=2000)
    sc.pp.pca(adata, n_comps=30)
    sc.pp.neighbors(adata, n_neighbors=15)

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.

scanpy-sc-analyzer is a skill published in the GitHub repository YuliaNuzhnenko/bioinformatics-agent-skills (9 stars, last pushed 2mo ago), licensed MIT. It adds 34 tokens to every session and 550 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
