Explain the ReAct Agent Loop
AMDSoftware Engineer · OnsiteLast updated
Explain a ReAct tool loop through state, action selection, observations, recovery, stopping criteria, and validation of task completion.
Explain the ReAct architecture for a tool-using agent. Describe how reasoning, actions, and observations interact and how the loop decides to continue or finish.
Constraints & Assumptions
Use a generic tool-enabled application with defined tool schemas. Focus on observable state transitions and decision quality; an action must be grounded in available tools and its result must be treated as an observation, not proof that the overall task succeeded.
Clarifying Questions
Which tools are available? What state persists across iterations? How are failures, time budgets, and completion checked? Which actions require external authorization?
Follow-up questions
- What prevents repeated ineffective tool calls? How should an agent handle an ambiguous tool result? When is a fixed workflow more reliable than an open-ended loop?
