arboreto

arboreto is a skill for Claude Code, Codex from agentlas-ai/agentlas-desktop. It costs 66 tokens per session (2,364 once invoked), scanned A, a copy of arboreto, Apache-2.0.

A Python library for inferring gene regulatory networks from gene-expression data. A gene regulatory network describes which transcription factors—proteins that control gene activity—may influence which target genes.

In plain words
What is it for?
Use it with bulk or single-cell RNA sequencing data to find likely transcription-factor and target-gene links using GRNBoost2 or GENIE3.
Why use it?
It turns large expression tables into candidate regulatory relationships and can distribute the computation across local or remote machines.

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

arboreto 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/basic_grn_inference.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Arboreto

Overview

Arboreto is a Python library from Aerts Lab for inferring gene regulatory networks (GRNs) from gene expression data. It parallelizes tree-based ensemble regression (GRNBoost2, GENIE3) with Dask across local cores or remote clusters.

Core capability: Identify which transcription factors (TFs) regulate which target genes based on expression patterns across observations (cells, samples, conditions).

Upstream: PyPI 0.1.6 (2021-02-09, latest). Docs: arboreto.readthedocs.io. Primary downstream consumer: pySCENIC.

Quick Start

Install arboreto:

uv pip install arboreto

Basic GRN inference:

import pandas as pd
from arboreto.algo import grnboost2

if __name__ == '__main__':
    # Load expression data (genes as columns)
    expression_matrix = pd.read_csv('expression_data.tsv', sep='\t')

    # Infer regulatory network
    network = grnboost2(expression_data=expression_matrix)

    # Save results (TF, target, importance)
    network.to_csv('network.tsv', sep='\t', index=False, header=False)

Critical: Always use if __name__ == '__main__': guard because Dask spawns new processes.

Core Capabilities

1. Basic GRN Inference

For standard GRN inference workflows including:

  • Input data preparation (Pandas DataFrame or NumPy array)
  • Running inference with GRNBoost2 or GENIE3
  • Filtering by transcription factors
  • Output format and interpretation

See: references/basic_inference.md

Use the ready-to-run script: scripts/basic_grn_inference.py for standard inference tasks:

python scripts/basic_grn_inference.py expression_data.tsv output_network.tsv --tf-file tfs.txt --seed 777 --limit 5000

2. Algorithm Selection

Arboreto provides two algorithms:

GRNBoost2 (Recommended):

  • Fast gradient boosting-based inference
  • Optimized for large datasets (10k+ observations)
  • Default choice for most analyses

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

arboreto is a skill published in the GitHub repository agentlas-ai/agentlas-desktop (6 stars, last pushed today), licensed Apache-2.0. It adds 66 tokens to every session and 2,364 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 88% identical to arboreto, differing in 348 lines, and is treated as a copy.
