monarch-database

monarch-database is a skill for Claude Code, Codex from vitaclaw/vitaclaw. It costs 68 tokens per session (3,336 once invoked), scanned A, original, no licence file.

A medical research knowledge graph for connecting diseases, genes, and observable traits across species. It combines information from several disease, genetics, clinical-variant, and model-organism databases.

In plain words
What is it for?
It helps with rare-disease gene discovery, matching observed traits to possible genes, comparing disease models across species, and looking up Human Phenotype Ontology terms.
Why use it?
It removes the need to search these separate sources one by one when investigating rare diseases and their possible genetic causes.

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

monarch-database 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 2mo 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.

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.
