Use the auto-generated `<AgentName>Client` type produced by the `#[agent_definition]` macro. Call `Client::get(...)` with the target agent's constructor parameters, then invoke methods on the client and await the results.

The calling agent obtains a client handle and invokes a method, which blocks until the target agent processes the request and returns a result. The target agent is created implicitly on first invocation if it does not already exist.

Yes. Declare the dependency in `golem.yaml` and run `golem build`, which generates bridge SDK code for inter-component dependencies. The generated client type for the remote agent then becomes available in your Rust project.

No. `Client::get(...)` does not create the agent; the agent is created implicitly on its first invocation. If an agent with those constructor parameters already exists, you receive a handle to the existing instance.

Deadlocks occur when agents form RPC cycles, such as A awaiting B while B awaits A. Break cycles by using fire-and-forget `trigger_` calls instead of awaited calls in one direction.

Use phantom agents, which allow multiple distinct instances sharing the same constructor parameters. This is covered separately from standard awaited RPC calls.
