borzoi

borzoi is a skill for Claude Code, Codex from companion-inc/feynman. It costs 41 tokens per session (208 once invoked), scanned A, original, MIT.

A set of workflows for using Borzoi, a model that predicts how DNA sequences may affect gene activity. It focuses on noncoding DNA, which does not directly encode proteins but can regulate genes.

In plain words
What is it for?
Use it to study noncoding genetic variants, design regulatory DNA sequences, and predict gene-expression effects across tissues or cell types.
Why use it?
It helps organize sequence and variant analyses while keeping genomic source data separate from model predictions.

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

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 10d 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

Borzoi

Use this skill for regulatory genomics modeling around sequence, variant, and expression effects.

Workflow:

  1. Pin genome build, interval coordinates, reference/alternate alleles, cell type or tissue, strand, and window size.
  2. Confirm the model route: local checkpoint, managed endpoint, notebook package, or external documented service. Record missing checkpoints as setup work, not as a completed model run.
  3. Build input FASTA/variant manifests with source URLs or accession IDs.
  4. Save prediction arrays, summary tables, plots, model version, and runtime metadata as Feynman artifacts.
  5. Compare predicted effects against GTEx, ENCODE, literature, or other source-backed evidence when available.

Keep source-owned genomic coordinates separate from model-owned effect predictions in every output.

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.

borzoi is a skill published in the GitHub repository companion-inc/feynman (8,870 stars, last pushed 14d ago), licensed MIT. It adds 41 tokens to every session and 208 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
