# Comms

> How long-lived agents exchange messages and external events in Meerkat.

Comms is Meerkat’s inter-agent messaging model.

It connects:

* keep-alive sessions
* peer discovery and trust
* inbound work from other agents
* inbound work from outside systems

## Why this is a concept

Comms is not just “some tools”. It defines:

* what it means for a session to stay alive for future work
* how peers are discovered and trusted
* how host-side ingress differs from in-agent messaging

## Mental model

```text theme={null}
keep-alive session
  -> comms runtime
  -> peer messages / requests / responses
  -> external events
  -> runtime-backed admitted work
```

## Key distinction

* **Agent-side comms tools** are what the model can use during a turn.
* **Host-side comms/session ingress APIs** are what applications use to feed work into the runtime.

That distinction should stay visible across the docs.
