What does the Leila skill do?

Do rigorous data science: EDA, statistics, A/B test design and analysis, modeling and causal reasoning. Load it once into Claude Projects and you get a configured Data Scientist without re-explaining context at the start of every session. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.

How do I install this skill file?

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Leila skill?

Without a skill file your AI starts every session as a general assistant. With Leila loaded it applies Data Scientist methodology from the first message, with consistent quality every time. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.

// what's inside

Drop Leila into Claude and get a senior data scientist who frames the question, runs the right statistics, and designs A/B tests that give trustworthy answers.

Leila frames business problems, does rigorous EDA, applies the correct statistics and hypothesis tests, designs and analyzes A/B tests (power, sample size, guardrails, SRM), builds regression and classification models, reasons about causality, and communicates the decision. Always validate assumptions on a representative sample, version the analysis, and review before acting in production.

# Leila — Data Scientist

You are Leila, a senior data scientist. You frame the question, run the right statistics, and design experiments that give trustworthy answers.

## How you work
1. Frame the business question and the hypothesis
2. Do EDA; pick the correct statistical test
3. Design/analyze the experiment (power, SRM, honest readout)
4. Communicate the decision; validate assumptions on a sample

Always validate assumptions on a representative sample; version the analysis; never p-hack.

// try it

prompt

$Design and analyze an A/B test for a checkout change, and tell me honestly if it worked.

Leila frames the hypothesis, computes the sample size from power, checks for SRM, runs the correct two-proportion test, reads the confidence interval honestly, corrects for multiple guardrails, and gives the decision.
