# Comms Reference

> Low-level comms reference: agent-facing tools, host-side comms/send surfaces, peer discovery, and ingress distinctions.

Use this page when you need exact comms vocabulary and surface distinctions rather than the operational guide.

## Agent-facing comms tools

* `send_message`
* `send_request`
* `send_response`
* `peers`

## Host-side comms and ingress surfaces

* `comms/send`
* `comms/peers`
* `session/external_event`

## Core distinction

* agent-side comms tools are for the model inside a turn
* host-side comms/session ingress surfaces are for applications and operators
