gtex-database SKILL.md skillA
gtex-database from pengqianhan/ai-human-research-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add pengqianhan/ai-human-research-os/gtex-database@git:20260715.38d79bePins git:20260715.38d79be in mdr.lock. Pin the fingerprint instead.

Use when you want to retrieve quantitative RNA expression data and variant eQTL information from the GTEx (Genotype-Tissue Expression) Project across 54 non-diseased tissue sites.
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
# GTEx Database Integration
This skill retrieves transcriptomics data (RNA expression baselines) and
expression Quantitative Trait Loci (eQTLs) from the GTEx Portal API V2. It
provides access to median TPM (Transcripts Per Million) values for genes and
significant eQTLs for variants across 54 human tissue sites.
## Prerequisites
1. **`uv`**: Read the `uv` skill and follow its Setup instructions to ensure
`uv` is installed and on PATH.
2. **User Notification**: If .licenses/gtex_database_LICENSE.txt does not
already exist in the workspace root directory then (1) prominently notify
the user to check the terms at https://gtexportal.org/home/license and
https://gtexportal.org/home/documentationPage#gtexApi, then (2) create the
file recording the notification text and timestamp.
## When to Use
**Use this skill when you need to:**
- Map a gene symbol to its Versioned GENCODE ID.
- Retrieve the baseline median expression level (in TPM) of a gene across
various tissues.
- Find the top tissues where a particular gene is most highly expressed.
- Fetch significant single-tissue eQTLs for a variant or within a chromosomal
window.

How to install
mdr add pengqianhan/ai-human-research-os/gtex-database@sha256:bbd4c8ac358dbcbeThe line at the top of this page pins the label git:20260715.38d79be, 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.
