medsci-agent: Skill for OpenCode

.opencode/skills/biopython/SKILL.md

biopython is a skill for OpenCode from omar-A-hassan/medsci-agent. It costs 21 tokens per session (270 once invoked), scanned A, original, MIT.

A Python toolkit for molecular biology data, especially DNA, RNA, and protein sequences. It can read FASTA files, calculate sequence statistics, translate DNA into protein, and work with alignments.

In plain words
What is it for?
Use it to parse FASTA files, inspect sequence composition and molecular weight, translate DNA, find sequence patterns, calculate protein properties, and analyze alignments.
Why use it?
It removes the need to write common sequence-processing code from scratch. It makes routine analysis of biological sequences easier to repeat.

Skill for OpenCode

Written for OpenCode: installed under .opencode/.

This is omar-A-hassan/medsci-agent's own configuration. It tells OpenCode how to work on medsci-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything medsci-agent configures →

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

biopython 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 7d 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.

What it actually says

BioPython — Molecular Biology Toolkit

When to Use

  • Parsing FASTA sequence files
  • Analyzing protein or nucleotide sequences
  • Computing sequence composition and molecular weight
  • Translating DNA to protein
  • Working with sequence alignments

Available Tools

  • parse_fasta(path) — Read FASTA file, return sequence metadata
  • analyze_sequence(sequence, seq_type) — Composition, MW, stats
  • analyze_sequence(sequence, seq_type="DNA", translate=true) — Translate DNA→protein

Amino Acid Properties

  • Hydrophobic: A, V, L, I, M, F, W, P
  • Polar: S, T, N, Q, Y, C
  • Positive: K, R, H
  • Negative: D, E
  • Special: G (flexible), P (rigid)

Common Sequence Analysis Tasks

  1. Check sequence length and composition
  2. Identify signal peptides (N-terminal Met + hydrophobic stretch)
  3. Find potential glycosylation sites (N-X-S/T)
  4. Calculate theoretical pI and MW
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.

biopython is a skill published in the GitHub repository omar-A-hassan/medsci-agent (18 stars, last pushed 5mo ago), licensed MIT. It adds 21 tokens to every session and 270 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
