via 0xfurai/claude-code-subagents
Master MQTT protocol implementation with optimized QoS, secure connections, and efficient IoT messaging patterns.
What is mqtt-expert?
Specializes in MQTT protocol architecture, message brokering, and IoT communication optimization. Use this agent to design topic hierarchies, configure QoS levels, implement security measures, and troubleshoot connection and delivery issues in MQTT systems.
- Design and validate MQTT topic hierarchies and message structures for efficient organization
- Configure and optimize QoS levels (0, 1, 2) based on use case requirements and latency constraints
- Implement secure client-broker communication with authentication, encryption, and connection lifecycle management
- Manage message retention, last will messages, and persistence strategies for reliable delivery
- Audit MQTT broker configurations for performance, scalability, and resource efficiency
- Troubleshoot connection issues, disconnections, and message delivery problems with monitoring and logging guidance
