bioskills-sparse-handling

bioskills-sparse-handling is a skill for OpenCode from ai4nucleome/BioMaster. It costs 32 tokens per session (209 once invoked), scanned A, original, no licence file.

A tool for storing and processing single-cell expression matrices efficiently. These matrices contain many zeros because most genes are inactive in each cell, so sparse storage avoids keeping unnecessary values.

In plain words
What is it for?
Use it to store, transform, and normalize zero-heavy expression data with scipy.sparse and AnnData.
Why use it?
It reduces memory use and makes large single-cell datasets easier to normalize and manipulate.

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

bioskills-sparse-handling 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.
