ユースケース

実用的な使い方： SciAgent-Skills

How to run a bulk RNA-seq differential expression analysis

👤 Biologists and bioinformaticians with FASTQ files and a need for DE results ⏱ ~120 min advanced

使うタイミング： You have paired-end FASTQ, a reference, and a condition table.

前提条件

Skill installed — git clone https://github.com/jaechang-hits/SciAgent-Skills ~/.claude/skills/sciagent-skills
Conda/mamba + compute — Use a Linux server or HPC; macOS fine for small datasets

フロー

Plan the pipeline

Plan a bulk RNA-seq DE workflow for 2 conditions x 3 reps with salmon + tximport + DESeq2. Output expected files per step.✓ コピーしました

→ Step list with tools and intermediate outputs
Run quantification

Run salmon quant for each sample; produce a script.✓ コピーしました

→ Bash script with salmon invocations
DE analysis

Load quants via tximport, run DESeq2, produce MA + volcano plots and a top-50 gene table.✓ コピーしました

→ R script + output files

結果： A DE table + plots you can hand to a PI or collaborator.

注意点

Mis-matched reference versus annotation GTF — Check release numbers explicitly; salmon and DESeq2 can silently run on mismatched IDs
Low-count filtering removes biological signal — Use independent filtering or raise threshold gradually; don't blanket filter

Single-cell RNA-seq QC and clustering baseline

👤 Researchers starting scRNA analysis from 10x output ⏱ ~90 min advanced

使うタイミング： You have a cellranger output directory and need a first-pass Seurat or Scanpy analysis.

フロー

Load + QC

Load 10x data from cellranger output, do QC (pct.mt, counts, features), filter, normalize.✓ コピーしました

→ QC plots + filtered object
Cluster

Run PCA, find neighbors, cluster at resolution 0.5, and UMAP.✓ コピーしました

→ Cluster labels + UMAP plot
Marker genes

Find cluster markers, produce a top-5-per-cluster heatmap.✓ コピーしました

→ Marker table + heatmap

結果： An annotated UMAP and marker table ready for biological interpretation.

注意点

Over-clustering at the default resolution — Try a sweep 0.2-1.0 and pick based on silhouette + biological plausibility

Germline variant calling from WGS

👤 Genomics teams calling SNPs and indels ⏱ ~180 min advanced

使うタイミング： You have aligned BAMs and need a VCF using best-practices (GATK).

フロー

Plan pipeline

Plan GATK best-practices germline pipeline from aligned BAMs: BQSR, HaplotypeCaller, joint genotyping with GenomicsDBImport.✓ コピーしました

→ Pipeline outline with expected runtimes
Generate scripts

Produce Snakemake rules for each step.✓ コピーしました

→ Snakefile with rules and config

結果： A reproducible Snakemake pipeline ready to run on your cluster.

注意点

Skipping BQSR on small cohorts — Still do it — GATK's downstream filters assume recalibrated quality scores

Triage small-molecule hits from a screen

👤 Med-chem groups triaging HTS results ⏱ ~60 min advanced

使うタイミング： You have a hit list and want to rank by drug-likeness + novelty.

フロー

Filter by Lipinski + PAINS

Compute Lipinski and PAINS flags on this SMILES list, output a filtered table.✓ コピーしました

→ RDKit-based script + filtered CSV
Similarity to known drugs

For remaining hits, compute Tanimoto similarity to ChEMBL approved drugs; flag >0.85 as known-scaffold.✓ コピーしました

→ Similarity table with flags

結果： A triaged hit list prioritized for follow-up.

組み合わせ

他のMCPと組み合わせて10倍の力を

sciagent-skill + filesystem

Read local FASTQ/BAM files and have SciAgent plan the analysis pipeline on actual data

List the FASTQ files in ~/data/rnaseq/, then use SciAgent to plan a salmon + DESeq2 pipeline for these samples.✓ コピーしました

sciagent-skill + github

Search nf-core or Bioconductor repos for reference implementations, then adapt with SciAgent

Search nf-core/rnaseq on GitHub for how they handle trimming, then use SciAgent to adapt that step for my pipeline.✓ コピーしました

ツール

このMCPが提供する機能

ツール	入力	呼び出すタイミング	コスト
Bulk RNA-seq workflow	FASTQ + design	Standard DE analysis	compute
scRNA-seq workflow	10x output	Single-cell baseline	compute
Variant calling	BAMs	WGS/WES cohorts	compute
Proteomics analysis	MS data	MS-based proteomics	compute
Drug discovery triage	SMILES list	Hit triage	compute

コストと制限

運用コスト

APIクォータ: None at skill level
呼び出しあたりのトークン: 10-50k per pipeline design
金額: Free skills; compute costs depend on dataset size
ヒント: Plan the pipeline as a script first, then run; don't keep Claude in the loop during long compute.

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： No credentials

データ送信先： Pipeline designs and snippets go to Claude. Actual patient data should stay on HIPAA-compliant compute.

Do not paste patient identifiers or raw sequence data that could be re-identified into prompts.
Always review generated variant-calling parameters — wrong caller settings can produce misleading results.

トラブルシューティング

よくあるエラーと対処法

tximport fails on missing transcript-to-gene mapping

Regenerate tx2gene from the same GTF you used for the salmon index; mismatch is the usual cause.

Seurat object too large for available RAM

Subsample or switch to on-disk storage with BPCells or DelayedArray-backed Seurat

Conda environment conflicts during pipeline setup

Use mamba instead of conda for faster resolution; pin exact versions in environment.yml rather than floating constraints

確認： mamba env create -f environment.yml --dry-run

Generated script references wrong genome build (hg19 vs hg38)

Explicitly state the genome build in your first prompt; SciAgent defaults may not match your data

代替案

SciAgent-Skills 他との比較

代替案	代わりに使う場面	トレードオフ
Galaxy / nf-core	You want audited, community pipelines rather than LLM-generated scripts	Less conversational; slower to customize
