writing-queries

What problem does it solve?

This Skill guides structured SQL query development to ensure correctness, documentation, and reproducibility in data analysis sessions.

Core Features & Use Cases

• Phase-driven query design: Clarifies the analytical question, selects tables, and plans calculations before writing code.
• Clean SQL with best practices: Comments, explicit aliases, proper NULL handling, and safe aggregations.
• Documentation & reproducibility: Generates traceable query notes and results for auditability.
• Use Case: When you need repeatable SQL analyses for dashboards, audits, or data science experiments.

Quick Start

Draft Phase 1 requirements and then generate a complete SQL query for a simple KPI, e.g., total revenue by region for last month.
