bedtools-genomic-intervals
jaechang-hits
"Toolkit for genomic interval operations on BED, BAM, GFF, VCF files. Find overlapping regions, merge adjacent intervals, calculate coverage depth, extract FASTA sequences, find nearest features, and manipulate interval coordinates. Essential for ChIP-seq peak annotation, target region filtering, and genome arithmetic. Use tabix instead for indexed single-region queries; use deeptools for normalized bigWig coverage."

testing
mcouthon
"Behavioral testing strategy — deciding what to test and how. Use when writing tests, reviewing test quality, or fixing tests that test mocks instead of behavior. Triggers on: 'use testing mode', 'write tests', 'test strategy', 'tests are brittle', 'tests test mocks', 'improve test quality', 'what should I test'. Full access mode - can write and run tests."
research-synthesis

review-pr
yonatangross
"PR review using parallel specialized agents for code quality, security, testing, architecture, and performance analysis. Synthesizes findings into a review report with conventional comments (praise/issue/suggestion/nitpick) and approve or request-changes verdict. Use when reviewing pull requests, conducting security audits, or validating changes before merge."
