primekg SKILL.md skillA
primekg from k-dense-ai/scientific-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add k-dense-ai/scientific-agent-skills/primekg@v1.4Pins v1.4 in mdr.lock. Pin the fingerprint instead.

Queries a pinned Precision Medicine Knowledge Graph (PrimeKG) CSV for typed gene, drug, disease, and phenotype nodes, direct associations, disease context, and one- or two-hop paths. Use for PrimeKG reproducibility, biological association lookup, and hypothesis generation with relation and data provenance preserved.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PrimeKG Knowledge Graph ## When to use Use for reproducing PrimeKG analyses, resolving entities in a specific graph artifact, or exploring recorded gene, drug, disease, phenotype, anatomy, and pathway associations. A path supports a research hypothesis; it does not establish causality, treatment efficacy, a prescribing recommendation, or a diagnostic conclusion. [PrimeKG upstream](https://github.com/mims-harvard/PrimeKG) now recommends OptimusKG for new work. This skill remains scoped to PrimeKG CSVs; the helper is not an OptimusKG client. Published PrimeKG integrates 20 resources, with approximately 129,000 nodes and 4.05 million undirected relationships. CSVs contain reverse rows, so row counts differ from distinct undirected relationship counts. Count the actual pinned artifact. ## 1. Pin and verify the input The [official dataset](https://doi.org/10.7910/DVN/IXA7BM) remained **V2.1**, published 2022-05-02, at the 2026-10-01 review. Its `kg.csv` has Dataverse file ID **6180620**, size **981751236 bytes**, and provider MD5 **aac8191d4fbc5bf09cdf8c3c78b4e75f**. The record declares **CC0 1.0**; upstream construction code is MIT.

How to install
mdr add k-dense-ai/scientific-agent-skills/primekg@sha256:b20698944fa51b28The line at the top of this page pins the label v1.4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
