feat: Add SQL Query Generator AgentKit

[aakritipp]

What This Kit Does

An AI-powered agent that converts natural language questions into optimized SQL queries. Users paste their database schema and ask questions in plain English. The agent returns production-ready SELECT queries with explanations, confidence scores, and assumption tracking.

Problem It Solves

Writing SQL from scratch is time-consuming, especially for complex joins and aggregations. This tool lets developers and analysts quickly get a working query by describing what they need in plain English.

Key Features

• Generates read-only SELECT queries only (never INSERT/UPDATE/DELETE/DROP)
• Returns structured output: SQL, explanation, tables used, assumptions, confidence
• Cross-database compatible (PostgreSQL, MySQL, SQLite)
• Handles ambiguous questions gracefully

Providers & Prerequisites

• Any LLM provider configured in Lamatic (e.g., Anthropic, OpenAI, Google)

How to Run Locally

1. cd kits/sql-query-generator/apps
2. npm install
3. cp .env.example .env.local and fill in values
