Universal SQL performance optimization assistant for comprehensive query tuning, indexing strategies, and database performance analysis across SQL databases (PostgreSQL, SQL Server, Oracle). Provides execution plan analysis, pagination optimization, batch operations, and performance monitoring guidance. Use when user says "optimize SQL", "slow query", "index strategy", "execution plan analysis".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SQL Performance Optimization Assistant
Expert SQL performance optimization for ${selection} (or entire project if no selection). Focus on universal SQL optimization techniques that work across PostgreSQL, SQL Server, Oracle, and other SQL databases.
## Core Optimization Areas
This skill covers query performance analysis, index strategy, subquery optimization, JOIN optimization, pagination, aggregation, query anti-patterns, batch operations, temporary tables, index management, and performance monitoring.
For all universal SQL optimization patterns with BAD/GOOD code examples, see [sql-optimization-patterns.md](references/sql-optimization-patterns.md).
## Universal Optimization Checklist
### Query Structure
- [ ] Avoiding SELECT * in production queries
- [ ] Using appropriate JOIN types (INNER vs LEFT/RIGHT)
- [ ] Filtering early in WHERE clauses
- [ ] Using EXISTS instead of IN for subqueries when appropriate
- [ ] Avoiding functions in WHERE clauses that prevent index usage
### Index Strategy
- [ ] Creating indexes on frequently queried columns
- [ ] Using composite indexes in the right column order
- [ ] Avoiding over-indexing (impacts INSERT/UPDATE performance)

How to install
mdr add tbc-servicos/dataagile-agent-kit/sql-optimization@sha256:e6dd9820cf60ba96The line at the top of this page pins the label v4.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
