When should Codex use multiple agents? A benchmark, not a slogan

说明与用途

Codex 仅在满足特定条件时使用多代理，以确保独立任务与冻结接口的收益能抵消额外的令牌和协调成本。

问题

Determining when to employ multiple agents in Codex workflows to balance coordination costs against potential benefits.

结果

The benchmark demonstrated feasibility of multi-agent orchestration but did not prove superiority in speed or cost; it highlighted specific conditions where orchestration can be beneficial, such as independent modules with frozen interfaces or specialist evidence gathering.

工作流

• Define task with frozen contract and independent write surfaces
• Assess if task has at least two genuine ownership surfaces
• Ensure exclusive paths and frozen interfaces
• Set controller to retain integration and final review
• Limit delegation to at most two workers
• Each worker returns concise evidence and changed files
• Controller integrates, evaluates, and writes receipt
• Measure acceptance, coverage, cost, elapsed time, coordination, integration, and human effort

证据

More agents do not automatically produce better engineering. They usually add total tokens, duplicated context, handoff delay, and integration risk.

来源

Use one agent when the change is small, the interface is unsettled, or several steps must edit the same central files.

The orchestrated candidate returned live browser evidence covering creation, filtering, state transitions, validation feedback, console errors, and a mobile viewport.
