In a multi-agent orchestration pattern, what is the role of the Reviewer Agent?

Question

BlackTom AI · Accepted Answer

The Reviewer Agent inspects and verifies outputs, ensuring they meet quality, correctness, and policy requirements before the output proceeds to the next stage.

1) Relevant knowledge points and concepts
- Multi-agent orchestration decomposes work into roles: planners/orchestrators (define workflow), executors/worker agents (perform tasks and API calls), reviewers/validators (check and possibly correct outputs), and human approvers (final sign-off when needed).
- A Reviewer Agent focuses on validation: semantic correctness, formatting, compliance, and consistency with requirements or earlier steps. It acts as a quality gate in pipelines.

2) Step-by-step reasoning process
- Step 1: Planner/Orchestrator defines workflow and assigns tasks.
- Step 2: Executor agents perform tasks (e.g., call APIs, generate content, run computations).
- Step 3: The Reviewer Agent receives the executor’s outputs and evaluates them against acceptance criteria (requirements, tests, policy checks).
- Step 4: If the output passes validation, the Reviewer forwards it to the next stage; if it fails, it requests revision or routes it back to the executor for correction.
- Step 5: Optionally, a human approver may give final sign-off after the Reviewer accepts the output.

3) Calculations
- No numeric calculations are required for this conceptual role-based question.

4) Why the correct answer is correct
- “Validates the output before it moves forward” precisely captures the Reviewer’s responsibility as the quality-control gate that ensures outputs are acceptable before progression, aligning with standard orchestration patterns.

5) Why the other options are incorrect
- “Performs API calls and executes tasks” describes an executor/worker agent, not the reviewer.
- “Grants final human approval” describes a human-in-the-loop approver, not an automated reviewer.
- “Defines the steps the workflow should follow” describes the planner/orchestrator, not the reviewer.

6) Conclusion
- Therefore, the correct role of the Reviewer Agent is to validate the output before it moves forward, which matches the provided answer: “Validates the output before it moves forward.”
