About gtars
gtars
Supports Gtars for local genomic interval models and set algebra
gtars is an agent skill for Gtars, a library for genomic interval and reference-sequence work. It provides native Rust implementations, Python bindings and a feature-gated gtars command-line binary. The skill covers local genomic interval models and set algebra, overlaps and counts, consensus and coverage, tokenisation and fragment processing. It advises starting with the bundled local inspectors, and calling upstream code only after the data contract, provenance, resource limits and side effects are clear. The skill records a verified snapshot dated 1 October 2026, so you can see which versions the examples were checked against. Use it when you are working with sets of genomic intervals, such as BED-style regions, and need to compare them, count overlaps, build coverage, or tokenise intervals for machine learning. It is part of the k-dense-ai scientific agent skills repository on GitHub, which has about 49,600 stars. The listing shows it as free, and it has about 1,800 installs. Its security audits show passes from Gen Agent Trust Hub, Socket and Snyk. Install it with npx skills add https://github.com/k-dense-ai/scientific-agent-skills --skill gtars.
