minimap2-read-mapping-starter

minimap2-read-mapping-starter is a skill for Claude Code, Codex from ma-compbio-lab/SkillFoundry. It costs 0 tokens per session (315 once invoked), scanned A, original, Apache-2.0.

A small-read mapping workflow that compares DNA sequencing reads in FASTQ files with a reference sequence using minimap2. It sorts and indexes the results in BAM format and reports basic alignment statistics.

In plain words
What is it for?
Use it for short-read alignment, creating an indexed BAM file, and checking mapped and unmapped reads, mapping quality, and example alignments.
Why use it?
It provides a repeatable way to check whether reads match a reference before doing tasks such as measuring gene activity or finding variants.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./slurm/envs/genomics/bin/python skills/genomics/minimap2-read-mapping-starter/scripts/run_minimap2_read_mapping.py \.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

minimap2-read-mapping-starter 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 5d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/run_minimap2_read_mapping.py, tests/test_run_minimap2_read_mapping.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

minimap2 Read Mapping Starter

Use this skill to align a tiny FASTQ file against a small reference with minimap2, sort and index the resulting BAM, and summarize the alignments.

What it does

  • runs minimap2 -a -x sr from the repo-managed genomics prefix
  • sorts and indexes the alignment with samtools
  • reports mapped and unmapped reads, mean MAPQ, and representative alignments

When to use it

  • you need a verified starter for alignment-and-mapping
  • you want a minimal short-read mapping example before adding quantification or variant calling
  • you need a deterministic BAM-producing smoke fixture

Example

./slurm/envs/genomics/bin/python skills/genomics/minimap2-read-mapping-starter/scripts/run_minimap2_read_mapping.py \
  --reference skills/genomics/minimap2-read-mapping-starter/examples/toy_reference.fa \
  --reads skills/genomics/minimap2-read-mapping-starter/examples/toy_reads.fastq \
  --bam-out scratch/genomics/minimap2/toy_reads.bam \
  --summary-out scratch/genomics/minimap2/toy_reads_summary.json

Verification

  • Skill-local tests: python3 -m unittest discover -s skills/genomics/minimap2-read-mapping-starter/tests -p 'test_*.py'
  • Expected summary: read_count == 3, mapped_count == 2, reference_names == ["chrToy"]
Files

What ships with it

9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

minimap2-read-mapping-starter is a skill published in the GitHub repository ma-compbio-lab/SkillFoundry (38 stars, last pushed 4mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 315 tokens. 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 2026-09-03.
