How do I install the Crispr Guide Design skill?

Run npx skillmds@latest add bg-szy/crispr-guide-design in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Crispr Guide Design skill do?

Guide foundry It is listed under Coding & Dev Tools on SkillMD.

Is Crispr Guide Design safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

File contents

CRISPR Design Agent

Automate sgRNA selection, scoring, off-target evaluation, and oligo generation for CRISPR experiments using the documented workflow.

When to Use

Designing CRISPR knockout/knock-in experiments that need validated guides.
Locating all PAM-compatible target sites in a gene or locus.
Filtering guides by efficiency/off-target metrics before cloning.

Core Capabilities

Target discovery: Scan sequences for PAM motifs (e.g., NGG).
Efficiency scoring: Evaluate GC content, homopolymers, Doench/DeepCRISPR/CFD scores.
Filtering & ranking: Remove risky guides (SNP overlap, off-target hits) and output the best candidates.

Workflow

Resolve gene symbol + organism to canonical transcript coordinates and target region.
Enumerate PAM-compatible sites; extract spacers for the chosen Cas variant.
Score guides (efficiency + specificity) and compute GC metrics.
Run off-target search (≤3 mismatches) to flag problematic loci.
Filter/rank guides, generate cloning oligos/primers, and emit JSON/CSV outputs with coordinates.

Example Usage

python3 Skills/Genomics/CRISPR_Design_Agent/crispr_designer.py \
    --sequence "ATGGAGGAGCCGCAGTCAGATCCTAGCGTCGAGCCCCCTCTGAGTCAGGAAACATTTTCAGACCTATGGAAACTGTGAGTGGATCCATTGGAAGGGC" \
    --output guides.json

Guardrails

Always state genome build and Cas variant assumptions.
Avoid guides overlapping common SNPs when avoid_variants is true.
Flag high off-target density near coding regions for manual review.
