Sub-agent

You might say

Can I split a big task among a few helpers at the same time, then get one combined result?

A separate agent the main agent assigns to a bounded part of a larger taskBefore release, a main agent can ask one sub-agent to review copy and another to check mobile layout, then combine their evidence. Each sub-agent needs a clear scope, permissions, and expected return.

Worker Agent

Split a release review into three independent checks

The main Agent defines each subtask’s goal, input, permissions, and delivery format so multiple Agents do not do the same work.

Sub Agents suit clearly bounded work that can be verified independently; splitting work also adds coordination cost.

How a main agent delegates and combines work

Split bounded work first: Assign separate accessibility, test, or documentation checks with clear read/write boundaries and completion criteria.

Work in separate context: Each sub-agent can focus on its own evidence and tools, returning only the relevant conclusions.

The main agent synthesizes: It waits for required evidence, resolves overlap or conflict, and forms one final result. Shared-file edits need clear ownership or sequencing.

You can say this to an AI Agent

Split this pre-release review across three read-only subagents: one for accessibility, one for API error handling, and one for test gaps. Each must return file locations and evidence without editing code. Wait for all three, merge duplicates, and produce one risk-ranked list. Ask me before making changes.

Before release, accessibility, API error handling, and test gaps must be reviewed. All three checks are read-only and can produce independent evidence. What is the better arrangement?

A. Give several subagents the same instruction to check everything, without scope, evidence requirements, or a return formatB. Assign one read-only subagent to each scoped check, then have the main agent wait, deduplicate, and summarizeC. Have three subagents rewrite the same configuration file at once without ownership boundaries
