} Use when
- Task needs a wide range of ideas or solution approaches
- A single agent keeps converging on the same answer
- A coordinator agent or human can synthesize the outputs
Avoid when
- Task has one clear correct answer
- Budget cannot cover several parallel agent runs
Problem
For complex problems or creative ideation, a single AI agent instance might get stuck in a local optimum or fail to explore a diverse range of solutions. Generating a breadth of ideas can be challenging for a sequential, monolithic process.
Solution
Employ a multi-agent approach for brainstorming and idea generation. This involves:
- Defining a core problem or task.
- Spawning multiple independent (or semi-independent) AI agent instances.
- Assigning each agent the same initial task or slightly varied perspectives on the task.
- Allowing each agent to work in parallel to generate ideas, solutions, or approaches.
- Collecting the outputs from all agents.
- Optionally, a coordinating agent or a human user can then synthesize these diverse outputs, identify common themes, or select the most promising ideas for further development.
This pattern leverages parallelism to explore a wider solution space and can lead to more creative or robust outcomes than a single agent might produce alone.
Example (parallel brainstorming)

A[Core Problem/Task] --> B[Agent 1: Perspective A]
A --> C[Agent 2: Perspective B]
A --> D[Agent 3: Perspective C]
B --> E[Solution Set 1]
C --> F[Solution Set 2]
D --> G[Solution Set 3]
E --> H[Coordinator/Human]
F --> H
G --> H
H --> I[Synthesized Solutions]
H --> J[Common Themes]
H --> K[Best Ideas Selected]
Example
- "Use 3 parallel agents to brainstorm ideas for how to clean up
@services/aggregator/feed_service.cpp." (from Claude Code examples)
How to use it
- Use this when you need diverse perspectives or want to avoid local optimum trapping.
- Assign distinct roles or perspectives to each agent (e.g., critic, optimist, technical realist).
- Limit to 2-4 agents for manageable coordination (practitioner guidance, not a measured threshold); note that research on sampling-and-voting finds accuracy generally improves with more agents, so add agents when the task rewards coverage and you can afford the runs.
- Use a coordinating agent or human to synthesize and deduplicate outputs.
Trade-offs
- Pros: Explores wider solution space, reduces local optimum trapping, enables diverse perspective exploration.
- Cons: Adds orchestration complexity, coordination overhead increases with agent count, requires synthesis mechanisms.
