algo-mst-kruskal-prim

algo-mst-kruskal-prim is a skill for Claude Code, Codex from Pavel-Kravchenko/Bioinformatics. It costs 68 tokens per session (2,086 once invoked), scanned A, original, no licence file.

A Python and NetworkX tool for finding a minimum spanning tree: the lowest-total-cost set of links that connects every point in a network. It uses the Kruskal or Prim algorithm.

In plain words
What is it for?
Use it for phylogenetic distance trees, gene co-expression network backbones, minimum-spanning-tree clustering, and Union-Find implementations.
Why use it?
It avoids implementing or choosing the network algorithm from scratch when you need a connected network with minimal total link cost.

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

algo-mst-kruskal-prim 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 12d 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.

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.
