peak-annotation SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

peak-annotation from ammawla/encode-toolkit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

Guide for annotating ENCODE peaks with genomic features using ChIPseeker and GREAT. Use when users need to assign peaks to genes, determine genomic feature distribution (promoter, intron, intergenic), or perform gene ontology enrichment of peak-associated genes. Trigger on: peak annotation, ChIPseeker, GREAT, peak to gene, genomic feature, promoter enrichment, gene ontology, peak distribution, TSS distance, nearest gene.

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

# Peak Annotation of ENCODE Data

## When to Use

- User wants to annotate genomic peaks with nearby genes, regulatory features, or functional categories
- User asks about "peak annotation", "ChIPseeker", "gene assignment", or "peak-to-gene mapping"
- User needs to classify peaks as promoter, enhancer, intronic, intergenic, etc.
- User wants to run GO/pathway enrichment on genes near their peaks
- Example queries: "annotate my H3K27ac peaks with nearby genes", "what genes are near these ATAC-seq peaks?", "run pathway analysis on peak-associated genes"

Help the user annotate ENCODE peak calls with genomic features and functional enrichment. Peak annotation bridges the gap between regulatory elements (peaks) and biological function (genes, pathways). This skill covers two complementary approaches: ChIPseeker for genomic feature annotation and visualization, and GREAT for functional enrichment analysis of non-coding regions.

How to install

The exact contents, by fingerprint
mdr add ammawla/encode-toolkit/peak-annotation@sha256:9c26b29e3ef8de63

The line at the top of this page pins the label git:20260920.6050003, 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.
