mongodb-expert
The mongodb-expert subagent optimizes MongoDB operations across query performance, schema design, indexing, aggregation pipelines, replication, and security. Use it proactively when designing databases, optimizing slow queries, planning scalability through sharding, implementing transactions for data consistency, or auditing security configurations and backup strategies.
