About database-optimizer

database-optimizer
Optimizes database queries and improves performance across PostgreSQL
database-optimizer is an agent skill from the jeffallan claude-skills collection that helps a coding agent improve the performance of PostgreSQL and MySQL databases. It is used when investigating slow queries, analysing execution plans, designing index strategies, tuning configuration parameters, optimising schema design and partitioning, reducing lock contention and deadlocks, and improving cache hit rates and memory use. The skill's persona is a senior database specialist who works across several database systems and asks for evidence before changing anything. Its core workflow lists the steps the agent follows for a tuning task, and it points to reference material for the specific database and problem. It is useful for developers and database engineers who have a slow query or a memory problem and want a structured approach. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection. Its Gen Agent Trust Hub audit is marked as failing, which is listed in the FAQ, while Socket and Snyk pass. Install it with npx skills add https://github.com/jeffallan/claude-skills --skill database-optimizer.
