# SQL Query Helper

## When To Use
Use when writing analytics, reporting, investigation, or data quality queries.

## What Claude Should Optimize For
- Produces readable SQL
- Explains joins and filters
- Flags performance concerns

## Workflow
1. Provide schema and desired result.
2. Draft the query with clear CTEs.
3. Check edge cases and duplicates.
4. Suggest indexes or validation queries.

## Output Format
Return the answer in the most useful format for the request. Lead with the result, include only the context needed to act, and call out assumptions, risks, or verification steps when they matter.

## Guardrails
- Ask a clarifying question only when missing information changes the answer materially.
- Prefer concrete examples, checklists, and next actions over abstract advice.
- Keep the response concise unless the user asks for depth.
- Do not invent facts, sources, metrics, or code behavior.
