Agent Building

Triggering a MoonBit Golem agent invocation without waiting for the result. Use when the user asks to fire-and-forget, trigger asynchronously, or enqueue an agent call from within agent code.

Fire-and-Forget Agent Invocation (MoonBit)

Overview

A fire-and-forget call enqueues a method invocation on the target agent and returns immediately without waiting for the result. The target agent processes the invocation asynchronously. This is for agent-to-agent calls from code, not from the CLI.

For CLI fire-and-forget, see the golem-trigger-agent-moonbit skill.

Usage

Every method on the auto-generated AgentClient has a corresponding trigger_ variant. Use AgentClient::scoped to obtain a client instance, then call the trigger_ method:

AgentClient::scoped("my-counter", fn(client) raise @common.AgentError {
  client.trigger_increment()
})

With arguments:

DataProcessorClient::scoped("pipeline-1", fn(client) raise @common.AgentError {
  client.trigger_process_batch(batch_data)
})

When to Use

Breaking RPC cycles: If agent A calls agent B and B needs to call back to A, use trigger_ for the callback to avoid deadlocks
Background work: Enqueue work on another agent without blocking the current agent
Fan-out: Trigger work on many agents in parallel without waiting for all results
Event-driven patterns: Notify other agents about events without coupling to their processing time

Example: Breaking a Deadlock

// In AgentA — calls AgentB and waits
AgentBClient::scoped("b1", fn(client) raise @common.AgentError {
  let result = client.do_work(data) // OK: awaited call
  // ...
})

// In AgentB — notifies AgentA without waiting (would deadlock if awaited)
AgentAClient::scoped("a1", fn(client) raise @common.AgentError {
  client.trigger_on_work_done(result) // OK: fire-and-forget
})

Example: Fan-Out

let regions : Array[String] = ["us-east", "us-west", "eu-central"]
for region in regions {
  RegionProcessorClient::scoped(region, fn(client) raise @common.AgentError {
    client.trigger_run_report(report_id)
  })
}

CLI Equivalent

From the command line, use --trigger:

golem agent invoke --trigger 'CounterAgent("my-counter")' increment
