scribble

scribble is a skill for Claude Code, Codex from CHENyiru3/AI-Skills-Collections. It costs 30 tokens per session (434 once invoked), scanned A, original, MIT.

A tool guide for combining several kinds of single-cell biology data, such as gene activity, DNA accessibility, and protein measurements. Single-cell analysis studies measurements from individual cells rather than averaging across a whole sample.

In plain words
What is it for?
It is for combining RNA, ATAC, and protein data, working with paired multi-omics samples, and creating unified cell embeddings. Multi-omics means analysing multiple biological measurement types together.
Why use it?
Separate measurement types describe different parts of the same cells and are difficult to compare directly. Integration creates a shared representation for analysing them together.

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

scribble 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 6d 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.

What it actually says

Scribble: Multi-Omics Integration

Overview

Scribble is a tool/package for multi-omics integration in single-cell analysis. It provides methods for integrating different modalities (gene expression, chromatin accessibility, protein) to create unified representations of cells.

When to Use This Skill

This skill should be used when:

  • Integrating multiple single-cell modalities
  • Performing multi-omics integration
  • Creating unified embeddings from heterogeneous data
  • Analyzing paired multi-omics data

Quick Start

Installation

pip install scribble

# Or from GitHub
pip install git+https://github.com/username/scribble.git

Basic Usage

import scribble
import scanpy as sc
import numpy as np

# Load multi-modal data
rna = sc.read_h5ad("rna.h5ad")
atac = sc.read_h5ad("atac.h5ad")
protein = sc.read_h5ad("protein.h5ad")

# Integration
combined = scribble.integrate(
    [rna, atac, protein],
    method="cca"  # or "mnn", "wnn"
)

Integration Methods

CCA Integration

# Canonical Correlation Analysis
combined = scribble.integrate(
    [rna, atac],
    method="cca",
    n_components=50
)

WNN (Weighted Nearest Neighbors)

# Weighted nearest neighbors
combined = scribble.integrate(
    [rna, protein],
    method="wnn"
)

Best Practices

  1. Preprocess each modality: Normalize and select features
  2. Check for batch effects: Verify integration quality

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.

scribble is a skill published in the GitHub repository CHENyiru3/AI-Skills-Collections (1 stars, last pushed 7d ago), licensed MIT. It adds 30 tokens to every session and 434 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 2026-10-02.
