The core agent protocol. Every agent type implements this.

Each agent is a struct with at minimum a name field. The protocol provides polymorphic dispatch for running agents and accessing metadata.

Implementing a custom agent

defmodule MyAgent do
  @enforce_keys [:name]
  defstruct [:name, description: "", sub_agents: []]

  defimpl ADK.Agent do
    def name(agent), do: agent.name
    def description(agent), do: agent.description
    def sub_agents(agent), do: agent.sub_agents
    def run(agent, ctx), do: [ADK.Event.new(%{author: agent.name, content: "hello"})]
  end
end
