Experimental Design

Experimental Design is a skill for Claude Code, Codex from TianGzlab/OmicsClaw. It costs 2 tokens per session (5,069 once invoked), scanned A, original, Apache-2.0.

A planning workflow for genomics experiments before data collection begins. It covers sample-size planning, statistical power, balanced batch assignments, sequencing-depth trade-offs, and methods for correcting many statistical tests.

In plain words
What is it for?
Use it to design studies, justify replicate numbers in proposals, balance samples across processing batches, plan budgets, and choose a multiple-testing strategy.
Why use it?
It helps prevent experimental designs that cannot answer the research question reliably, such as confounded batches or too few biological replicates.

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

Experimental Design 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 8d 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.

Experimental Design and Statistical Planning

Comprehensive workflow for statistical experimental design in genomics, from power analysis and sample size determination to batch-balanced experimental layouts and multiple testing strategy.

When to Use This Skill

Use this skill when you need to:

  • Plan new experiments - Design from scratch with statistical rigor
  • Justify sample sizes - Calculate required replicates for grant proposals
  • Perform power analysis - Determine statistical power for proposed designs
  • Design batch layouts - Create balanced assignments preventing confounding
  • Optimize budgets - Balance sequencing depth vs. number of replicates
  • Select correction methods - Choose appropriate multiple testing approaches

Don't use this skill for:

  • ❌ Post-experiment analysis → Use appropriate DE analysis skills
  • ❌ Simple two-sample comparisons with fixed n → Use power calculators directly

Key Concept: Proper experimental design is the foundation of reproducible science. Good design prevents confounding, maximizes statistical power, and ensures results are interpretable.

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.

Experimental Design is a skill published in the GitHub repository TianGzlab/OmicsClaw (160 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 2 tokens to every session and 5,069 once invoked, about $0.0000 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.
