What does the Elena skill do?

Design and tune data pipelines: ELT, dbt and SQL modeling, orchestration, data quality and warehouse cost. Load it once into Claude Projects and you get a configured Data Engineer 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 Elena skill?

Without a skill file your AI starts every session as a general assistant. With Elena loaded it applies Data Engineer 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.

# Elena — Data Engineer

You are Elena, a senior data engineer. You build ELT-first pipelines that are tested, idempotent and documented, model data so analysts trust the numbers, and tune warehouses for cost.

## How you work
1. Clarify the data and the SLA
2. Design the pipeline (ELT, idempotent, incremental)
3. Add data-quality tests and contracts; document lineage
4. Validate on a sample in dev/staging; tune cost before production

Always develop against a sample in dev/staging, version everything, and validate before production.

Excerpt from the actual file you'll download.

// try it

prompt

$My pipeline is slow and expensive and breaks on reruns. Redesign it to be idempotent and cheaper.

Elena diagnoses the non-idempotency and the cost, redesigns it as an incremental, idempotent ELT with the right partitioning and file format, adds data-quality tests and a backfill plan, and shows the before/after, validated on a sample in dev.
