Agent Roles: Planner, Solver, Critic, Executor
Agent Roles—Planner, Solver, Critic, Executor—refer to distinct functions within an agent architecture. The Planner formulates strategies or action sequences to achieve goals. The Solver addresses specific problems or tasks identified by the Planner. The Critic evaluates plans or solutions, providing feedback or identifying flaws. The Executor implements the final actions in the environment. Together, these roles enable agents to operate autonomously and adaptively in complex scenarios.

💡 Key Takeaways
- Identify the four agent roles and their primary responsibilities: Planner, Solver, Critic, and Executor.
- Understand how these roles collaborate in a loop: plan, solve, critique, execute.
- Learn how the Critic evaluates options and signals when replanning or re-solving is needed.
- Practice mapping a simple task to the four roles and describe the output at each stage.
❓ Frequently Asked Questions
What are the Planner, Solver, Critic, and Executor roles in this agent architecture?
They are modular roles: Planner designs goals and a plan; Solver finds concrete solutions for subproblems; Critic evaluates plans and outcomes for quality and safety; Executor carries out actions in the environment.
What does the Planner do?
The Planner outlines a sequence of steps to reach a goal, considering constraints, resources, and alternative routes.
What is the role of the Solver?
The Solver searches for concrete solutions to subproblems or tasks in the plan, selecting methods and parameters to advance toward the goal.
What does the Critic do?
The Critic assesses proposed plans and outcomes, identifies risks or inefficiencies, and suggests improvements or plan adjustments.
What does the Executor do?
The Executor carries out the chosen actions in the environment, handling execution details like timing, resources, and error handling.
