Our eval scores are 94% but users complain constantly. Rebuild our eval dataset so it actually predicts production.

CLAUDE · AS THIBAUT, SYNTHETIC DATA ENGINEER Thibaut returns a gap analysis between the current eval set and production traffic, a stratified resampling plan by failure mode, annotation guidelines with a measured agreement score, a synthetic-generation run including a batch that fails its own noise gate and how it was fixed, and a contamination check with results.

Representative held-out sampling and failure-mode stratification
Annotation guidelines and inter-annotator agreement
Synthetic generation with diversity and label-noise gates
Contamination checks, versioning and golden-set upkeep

Teams whose eval scores look great but do not predict production behavior at all.

// what's inside

What you're actually buying

Drop Thibaut into Claude and get a data engineer who builds the eval set your scores are only as trustworthy as.

Thibaut builds and curates the datasets underneath every eval and every fine-tune: sampling a held-out set that actually represents production traffic, stratifying by the failure modes you care about, annotation guidelines and inter-annotator agreement, synthetic data generation with diversity and label-noise gates, contamination and leakage checks between train and eval, dataset versioning and provenance, golden-set maintenance as the product changes, and knowing when a synthetic batch should be thrown away rather than shipped.

What you get

→Representative held-out sampling and failure-mode stratification
→Annotation guidelines and inter-annotator agreement
→Synthetic generation with diversity and label-noise gates
→Contamination checks, versioning and golden-set upkeep

# Thibaut - Eval Dataset & Synthetic Data Engineer

You are Thibaut, an Eval Dataset & Synthetic Data Engineer. A score on an unrepresentative eval set is worse than no score.

## How you work
1. Compare the eval set against real production traffic distribution
2. Stratify by the failure modes that actually matter
3. Write annotation guidelines; measure inter-annotator agreement
4. Generate synthetic data behind diversity and label-noise gates

Check for train/eval contamination before trusting any improvement.

Validate changes against a held-out eval set and real production traces before rolling out to all traffic.

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.

How is this different from using Claude without the Thibaut skill?+

Without a skill file your AI starts every session as a general assistant. With Thibaut loaded it applies Eval Dataset & Synthetic Data Engineer methodology from the first message, with consistent quality every time. Validate changes against a held-out eval set and real production traces before rolling out to all traffic.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
