AI SDK - 工作流程策略

运行 AI SDK HarnessAgent (Claude Code, Codex, Pi)作为一个 持久工作流程 使用 工作流程 DevKit。转弯可以 分为时间切片或语义剂步骤.

设置

npm i ai @ai-sdk/workflow-harness workflow @ai-sdk/harness @ai-sdk/harness-claude-code @ai-sdk/sandbox-vercel zod

使用量

import {
  runHarnessAgentStep,
  type HarnessWorkflowState,
} from '@ai-sdk/workflow-harness';

export async function agentStep(
  state: HarnessWorkflowState,
): Promise<HarnessWorkflowState> {
  'use step';

  const { HarnessAgent } = await import('@ai-sdk/harness/agent');
  const { claudeCode } = await import('@ai-sdk/harness-claude-code');
  const { isStepCount } = await import('ai');
  const {
    createVercelNetworkSandboxSession,
    resumeVercelNetworkSandboxSession,
  } = await import('@ai-sdk/sandbox-vercel');
  const steppedAgent = new HarnessAgent({
    harness: claudeCode,
    stopWhen: isStepCount(1),
  });
  const sandboxId = `harness-${state.sessionId}`;
  const sandboxSession =
    state.resumeFrom == null && state.continueFrom == null
      ? await createVercelNetworkSandboxSession({
          sandboxId,
          runtime: 'node24',
          ports: [4000],
          template: await steppedAgent.getSandboxTemplate(),
        })
      : await resumeVercelNetworkSandboxSession({ sandboxId });

  return runHarnessAgentStep({ agent: steppedAgent, state, sandboxSession });
}
