Fire-and-Forget Agent Invocation (TypeScript)

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.

Usage

Every method on a definition RPC client has a .trigger() variant. It takes the same input record as the awaited call but returns void immediately:

import { CounterAgent } from './counter-agent.js'; const counter = CounterAgent.client.get({ name: 'my-counter' }); // Fire-and-forget — returns immediately counter.increment.trigger(); // input: {} // With arguments const processor = DataProcessor.client.get({ name: 'pipeline-1' }); processor.processBatch.trigger({ batch: batchData });

For an agent in another component, the generated guest client exposes the same .trigger() method, but its constructor uses flattened id parameters:

import { CounterAgent } from 'counter-agent-guest-client'; CounterAgent.get('my-counter').increment.trigger();

See the golem-call-another-agent-ts skill for the required golem.yaml and tsconfig.json setup. Use the definition’s .client for same-component calls.

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

import { AgentA } from './agent-a.js'; import { AgentB } from './agent-b.js'; // In AgentA — calls AgentB and waits const b = AgentB.client.get({ name: 'b1' }); const result = await b.doWork({ data }); // OK: awaited call // In AgentB — notifies AgentA without waiting (would deadlock if awaited) const a = AgentA.client.get({ name: 'a1' }); a.onWorkDone.trigger({ result }); // OK: fire-and-forget

CLI Equivalent

From the command line, use --trigger (or -t) to enqueue an invocation without waiting:

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