bio-ortholog-inference

bio-ortholog-inference is a skill for Claude Code, Codex from PKU-YuanGroup/OpenAI4S. It costs 141 tokens per session (4,981 once invoked), scanned A, original, MIT.

A guide to retrieving precomputed ortholog relationships from public databases. Orthologs are genes in different species inherited from a common ancestral gene.

In plain words
What is it for?
Finding the equivalent gene in another species, querying orthology APIs, and comparing confidence or results across resources.
Why use it?
It saves you from recalculating relationships that databases have already inferred and helps explain why sources may disagree.

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

bio-ortholog-inference scanned grade A with 1 finding 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/compara_orthologs.py, scripts/cross_resource.py, scripts/kegg_orthology.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.

How it starts

The opening of the file, as written. The whole thing — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Version Compatibility

Reference examples tested with: requests 2.31+, pandas 2.2+; OrthoDB v12 API, Ensembl REST (Ensembl release 112+), OMA REST API, eggNOG 6.0+, PANTHER v18+

Before using code patterns, verify installed versions match. If versions differ:

  • Python: pip show requests pandas
  • API surface: confirm endpoint URLs and JSON schema match the current API docs

If endpoints return 404 or unexpected JSON, check release notes for the resource; schema migrations happen with each major version (Ensembl release is the biggest moving target).

Ortholog Inference (Database Access)

"What is the X ortholog of gene Y?" -> Many ortholog resources have already done the inference at scale. Pulling their answers is faster and often more reliable than re-computing. This skill is the database-access view: how to query the major orthology resources programmatically, what their confidence semantics mean, and when their disagreements matter.

For de novo orthology inference (running OrthoFinder, SonicParanoid, OMA standalone on local proteomes), see comparative-genomics/ortholog-inference — that's a much deeper treatment of the computational side.

This skill is about pulling answers from:

  • OrthoDB v12 — broadest coverage (1700+ species), levels from species-specific to deep

  • Ensembl Compara — vertebrate-focused, tree-reconciled, confidence scores

  • OMA browser — high precision, HOG (Hierarchical Orthologous Group) framework

  • eggNOG 6.0 — pre-computed functional groups, deepest functional annotation

  • PANTHER — protein family + ortholog calls with experimentally validated curation

  • KEGG Orthology (KO) — pathway-centric orthologous functional units

  • HomoloGene — deprecated since 2014, but data still queryable for legacy comparison

  • Python: requests.get() against REST endpoints; pandas for parsing

  • CLI: curl against the same endpoints; OrthoDB also has bulk downloads

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.

bio-ortholog-inference is a skill published in the GitHub repository PKU-YuanGroup/OpenAI4S (407 stars, last pushed yesterday), licensed MIT. It adds 141 tokens to every session and 4,981 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
