//! ACP toolset — multiple ACP agents as a single ADK Toolset.

/// A collection of ACP agents exposed as an ADK Toolset.
///
/// Each agent becomes a named tool that can be invoked by the parent ADK agent.

/// # Example
///
/// ```rust,ignore
/// use adk_acp::{AcpToolset, AcpAgentTool};
///
/// let toolset = AcpToolset::new("coding-agents")
///     .add(AcpAgentTool::new("claude-code").description("Complex refactoring"))
///     .add(AcpAgentTool::new("codex").description("Quick code generation"));
///
/// let agent = LlmAgentBuilder::new("orchestrator")
///     .toolset(Arc::new(toolset))
///     .build()?;
/// ```
