AI Agents
---------

[](#ai-agents)

Each agent is a self-contained microservice that generates [SWML](docs/swml_service_guide.md) (SignalWire Markup Language) and handles [SWAIG](docs/swaig_reference.md) (SignalWire AI Gateway) tool calls. The SignalWire platform runs the entire AI pipeline (STT, LLM, TTS) -- your agent just defines the behavior.
