# `Raxol.AgentClientProtocol.Schema.Ext`
[🔗](https://github.com/DROOdotFOO/raxol-agent/blob/raxol_agent_client_protocol-v0.1.0/packages/raxol_agent_client_protocol/lib/raxol/agent_client_protocol/schema/ext.ex#L1)

Extension types for ACP protocol extensibility.

ACP reserves method names prefixed with `_` (e.g. `_myext/doThing`) for
vendor/experimental extensions that aren't part of the core spec. Peers
that don't understand an extension method still parse it uniformly:

  * `Ext.ExtRequest` — an arbitrary `_`-prefixed request (expects a reply).
  * `Ext.ExtResponse` — the reply to an `ExtRequest`. Its wire
    representation is *transparent*: the response body IS the wrapped
    `data` term, not `%{"data" => ...}` — see the module doc there.
  * `Ext.ExtNotification` — an arbitrary `_`-prefixed notification (no
    reply expected).

Ported from the MIT `f1729/agent_client_protocol` (c) 2025 f1729; see NOTICE.md.

# `meta`

```elixir
@type meta() :: %{optional(String.t()) => term()} | nil
```

Free-form vendor metadata carried alongside a typed payload.
