# `Agentic.Protocol.ACP`

Generic ACP (Agent Client Protocol) implementation.

Implements `Agentic.AgentProtocol` for any ACP-compatible agent.
One module handles all ACP agents -- the agent identity (kimi, cursor, etc.)
is specified via backend config, not via separate modules.

## Usage

    # Direct use
    {:ok, session_id} = Agentic.Protocol.ACP.start(
      %{command: "kimi", args: ["acp"], workspace: "/path"},
      context
    )

    # Via registry
    Agentic.Protocol.Registry.register({:acp, :kimi}, Agentic.Protocol.ACP)
    {:ok, module} = Agentic.Protocol.Registry.lookup({:acp, :kimi})

## Backend Config

    %{
      command: "kimi",           # CLI binary name
      args: ["acp"],             # Arguments to enable ACP mode
      env: %{},                  # Extra environment variables
      workspace: "/path/to/dir", # Working directory (cwd)
      mcp_servers: [],           # MCP servers to forward to agent
      permission_policy: :ask    # :ask | :allow_all | :deny_all
    }

# `available_for?`

```elixir
@spec available_for?(String.t()) :: boolean()
```

Check availability for a specific agent command.

Unlike other protocols, ACP availability depends on the command
specified in the backend config. Use `available_for?/1` to check.
