alterlab-borzoi

alterlab-borzoi is a skill for Claude Code from AlterLab-IEU/AlterLab-Academic-Skills. It costs 164 tokens per session (1,015 once invoked), scanned A, original, MIT.

A DNA-sequence model that predicts functional genomic measurements across a long region, including RNA production, chromatin accessibility, and protein-DNA binding signals. It can compare reference and altered sequences to estimate regulatory effects.

In plain words
What is it for?
Use it to predict RNA-seq, CAGE, ATAC-seq, and ChIP-seq tracks, score non-coding variants, run in-silico mutagenesis, and rank candidate regulatory changes.
Why use it?
It helps prioritize changes outside protein-coding genes, where the impact on gene control is often difficult to assess directly. The predictions come from sequence rather than from a database lookup of known variants.

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

alterlab-borzoi 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 12d 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.

Borzoi (sequence → function)

Overview

Borzoi (Linder et al. 2025; calico/borzoi) is a sequence-to-function deep-learning model: given a DNA sequence over a long genomic context, it predicts genome-wide functional tracks — RNA-seq, CAGE, ATAC-seq, and ChIP coverage across many assays/tissues. Its headline use is non-coding variant effect scoring: run the reference and alternate alleles through the model and compare predicted tracks to estimate a regulatory variant's impact on expression or chromatin.

It predicts function from sequence; it does not look up known variants. For a variant's population frequency use alterlab-gnomad; for clinical significance use alterlab-clinvar.

When to Use This Skill

Use this skill when the user wants to:

  • Predict functional tracks (RNA-seq/CAGE/ATAC/ChIP) from a DNA sequence or locus.
  • Score a non-coding / regulatory variant's predicted effect (ref vs. alt).
  • Run in-silico mutagenesis to find driver bases in a regulatory element.
  • Prioritize candidate regulatory variants by predicted functional impact.

Does NOT Trigger

Scenario Use instead
Look up a variant's population frequency alterlab-gnomad
Look up a variant's clinical significance alterlab-clinvar
Predict a protein-structure / coding effect alterlab-alphafold
Single-cell foundation-model tasks alterlab-scgpt
Standard variant calling from reads alterlab-nf-core-sarek (or the relevant pipeline skill)

Core Capabilities

1. Track prediction from sequence

# calico/borzoi — API sketch; TODO(verify) against installed borzoi
# 1) extract the reference sequence window around a locus
# 2) run the model to get multi-track predicted coverage
# (see references/borzoi_usage.md for the exact model-loading + predict calls)

Provide a genome window (coordinates + reference, or a FASTA); the model returns predicted coverage across its output tracks.

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.
