Query the Monarch Initiative knowledge graph for disease-gene-phenotype associations across species.

  • Works in 5 steps: Phenotype-to-gene mapping - Find genes… → Disease-to-gene associations - Discover… → Cross-species ortholog discovery -… → …
  • Rare disease gene discovery
  • SKILL.md covers Overview, Core Capabilities, Key Workflows and Best Practices
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Monarch Database is an agent skill from lamm-mit/scienceclaw. Query the Monarch Initiative knowledge graph for disease-gene-phenotype associations across species. Integrates OMIM, ORPHANET, HPO, ClinVar, and model organism databases. Use for rare disease gene discovery, phenotype-to-gene mapping, cross-species disease modeling, and HPO term lookup.

Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management, covering Knowledge graphs. The licence is CC0-1.0.

When your agent uses it

  • Rare disease gene discovery
  • Phenotype-to-gene mapping
  • Cross-species disease modeling
  • HPO term lookup

Example prompts

  • “/monarch-database”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Phenotype-to-gene mapping - Find genes associated with human phenotype terms
  2. Disease-to-gene associations - Discover disease-causing genes using MONDO disease identifiers
  3. Cross-species ortholog discovery - Identify model organism orthologs for human genes
  4. HPO semantic similarity - Compare phenotype profiles between individuals/organisms
  5. Automated disease diagnosis - Build diagnostic algorithms from phenotype to gene lists

What it can do on your machine

Read from SKILL.md and the folder at commit ab9aba1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • monarchinitiative.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Monarch Database loads about 453 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 168 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~453

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Monarch Initiative Database

Overview

The Monarch Initiative (https://monarchinitiative.org/) is a multi-species integrated knowledgebase that links genes, diseases, and phenotypes across humans and model organisms. It integrates data from over 40 sources including OMIM, ORPHANET, HPO (Human Phenotype Ontology), ClinVar, MGI (Mouse Genome Informatics), ZFIN (Zebrafish), RGD (Rat), FlyBase, and WormBase.

Core Capabilities

The skill provides REST API v3 access for:

  1. Phenotype-to-gene mapping - Find genes associated with human phenotype terms
  2. Disease-to-gene associations - Discover disease-causing genes using MONDO disease identifiers
  3. Cross-species ortholog discovery - Identify model organism orthologs for human genes
  4. HPO semantic similarity - Compare phenotype profiles between individuals/organisms
  5. Automated disease diagnosis - Build diagnostic algorithms from phenotype to gene lists

Key Workflows

  • Rare disease gene discovery using patient phenotypes (HP terms)
  • Model organism selection for disease research
  • Phenotype-based patient stratification
  • Cross-species disease mechanism studies
  • Regulatory variant functional consequence prediction

Best Practices

Use standardized identifiers: MONDO for diseases, HP for phenotypes, HGNC for human genes. Leverage the integrated data from multiple curated sources for robust evidence accumulation.
