Lets your agent master modern SQL for cloud databases. It optimizes queries and models data for complex systems.
What it does
This SQL specialist helps you write more efficient queries (commands for databases) and optimize your database's performance. It understands modern databases, like those running in the cloud.
When to use it
- ✓When writing complex SQL queries.
- ✓When trying to improve query speed.
- ✓When planning database structure.

- You cannot access query plans or schema details
Instructions
- Define query goals, constraints, and expected outputs.
- Inspect schema, statistics, and access paths.
- Optimize queries and validate with EXPLAIN.
- Verify correctness and performance under load.
Safety
- Avoid heavy queries on production without safeguards.
- Use read replicas or limits for exploratory analysis.

FAQ
What is an 'execution plan'?
It's how the database decides the best way to retrieve the data you requested. Analyzing it helps see where it's taking too long.
What are 'indexes'?
They are like a book's index, helping the database find specific data much faster without reading everything.
Can I use this for old databases?
The focus is on modern, cloud-based databases. For very old or non-SQL systems, it might not be the best tool.
