Deploy

new AgentRuntime(configuration?, settings?) takes two independent, optional arguments — configuration (connection/auth, same shape as every other Conductor client) and settings (behavior-only: worker/streaming/liveness tuning). Both fall back to env vars, then defaults; see the runtime reference for the full option list.

import { AgentRuntime } from '@io-orkes/conductor-javascript/agents';

const runtime = new AgentRuntime();   // reads connection + behavior entirely from env

deploy vs serve vs run vs plan

Method	What it does	Local workers?
runtime.run(agent, prompt, opts?)	Compile + start + stream + return an AgentResult.	Yes — registers and polls local tool() workers for the run.
runtime.start(agent, prompt, opts?)	Same as run but returns an AgentHandle for async interaction (stream, approve, pause, ...).	Yes.
runtime.stream(agent, prompt, opts?)	start + return its AgentStream.	Yes.
runtime.deploy(agent, { schedules? })	Compile + register the workflow definition on the server. No execution, no workers. CI/CD step. Returns DeploymentInfo.	No.
runtime.deploy(...agents)	Variadic form: compile + register multiple agents in one call, no schedules reconciliation. Returns DeploymentInfo[].	No.
runtime.serve(...agents, { blocking? })	Deploys the given agents (same registration as deploy), registers their local tool workers, and starts polling. Blocks until SIGINT/SIGTERM by default; pass a trailing { blocking: false } to return once deploy + registration + polling have started. With no agents, just (re)starts polling for workers already registered.	Yes (and keeps them alive when blocking).
runtime.plan(agent)	Compile to a workflow definition and return it, without executing.	No.
runtime.shutdown()	Stop worker polling.	—

serve() already deploys, so a standalone deploy() call beforehand is optional — only worth doing when you want registration decoupled from worker start-up (e.g. a dedicated CI/CD step).

Production pattern

Compile/register with deploy() during a release step (or let serve() do it), then run one or more long-lived serve() worker processes for the tool workers. Trigger executions via the control plane (runtime.client.run(...)/start(...)) or schedules — not by calling run() from inside the worker process itself. Use plan() in CI to inspect the compiled workflow definition before it's deployed.

// Long-lived worker process -- deploys + registers workers + starts polling
await runtime.serve(myAgent);   // blocks

// Trigger (control plane, no local workers needed for LLM-only / remote-tool agents)
const result = await runtime.client.run(myAgent, 'do the thing');

Always call shutdown() (or dispose cleanly) for short-lived scripts so worker polling actually stops; a long-lived serve() process is expected to run until SIGINT/SIGTERM.

Recovering after a worker process restart

There's no execution-scoped reattach call (no resume(executionId)). Recovery is process-level: start a fresh serve() with no agents in the replacement process — it resumes polling for whatever tool workers are already registered on the server, covering every affected execution's domain at once. See stateful agents for how WorkerStallError/liveness monitoring surfaces the need to do this.

Plans / PLAN_EXECUTE

strategy: 'plan_execute' runs a planner sub-agent to produce a JSON plan, then executes it deterministically as a sub-workflow. You must provide a planner agent (and may provide a fallback):

const harness = new Agent({
  name: 'plan_harness',
  model: 'openai/gpt-4o',
  strategy: 'plan_execute',
  planner: plannerAgent,     // required — produces the JSON plan
  fallback: agenticAgent,    // optional — runs agentically if the plan can't compile/run
  tools: [/* tools the plan steps call */],
});
const result = await runtime.run(harness, 'Build a release report.');

You can also supply a deterministic static plan with the typed builders and pass it via RunOptions.plan — it wins over the planner's output (the planner still runs, but its output is discarded):

import { Plan, Step, Op, Generate, Ref } from '@io-orkes/conductor-javascript/agents';

const plan = new Plan({
  steps: [
    new Step('fetch', { operations: [new Op('fetch_data', { args: { source: 'db' } })] }),
    new Step('summarize', {
      dependsOn: ['fetch'],
      operations: [new Op('summarize', {
        generate: new Generate({
          instructions: 'Summarize the fetched data.',
          outputSchema: '{"type":"object","properties":{"summary":{"type":"string"}}}',
          context: new Ref('fetch'),     // reference a prior step's output
        }),
      })],
    }),
  ],
});

const result = await runtime.run(harness, 'Run the pipeline.', { plan });

Builders: Plan({ steps, validation?, onSuccess?, onFailure? }), Step(id, { operations?, dependsOn?, parallel? }), Op(tool, { args? | generate? }), Generate({ instructions, outputSchema, maxTokens?, context? }), Validation(tool, { args?, successCondition? }), Action(tool, { args? }), Ref(stepId), Context({ text? | url?, headers?, required?, maxBytes? }).

For planner reference docs, set plannerContext: [...] on the agent (strings or Context instances; URLs are fetched at runtime, no recompile).
