gtars

gtars is a skill for Claude Code from jimmc414/Kosmos. It costs 50 tokens per session (1,755 once invoked), scanned A, original, no licence file.

A fast toolkit for working with genomic intervals, meaning regions of DNA stored in files such as BED files, with Python support.

In plain words
What is it for?
Use it to analyse regions, coverage tracks, and sequencing fragments; detect overlaps; tokenize genomic regions; and support computational genomics or machine learning.
Why use it?
It speeds up common operations such as finding overlapping regions, measuring coverage, and preparing regions for machine-learning models.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gtars scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
