What mysql does

The skill covers MySQL query development and server administration. It can guide work with SELECT, JOIN, subqueries, INSERT, UPDATE, DELETE, stored procedures, triggers, and events. Its scope also includes database creation, users, privileges, the InnoDB and MyISAM engines, and character sets.

For performance work, it uses EXPLAIN, index tuning, the slow query log, and Performance Schema. It also covers mysqldump, binary logs, replication, Group Replication, MySQL Router, ProxySQL, and failover strategies. SQL fundamentals, Linux basics, and networking concepts are prerequisites, so those areas need to be familiar before tackling the administration tasks.

What it helps with

inspect a query plan with EXPLAIN
tune indexes and investigate slow queries
create MySQL users with the right privileges
plan backups with mysqldump
configure replication and a failover strategy

Example prompts for the agent

Review this MySQL query with several JOIN clauses and suggest suitable indexes.
Check the MySQL user setup and write SQL for the required privileges.
Plan a backup flow with mysqldump and outline the replication setup.
