Write pseudocode for a ReAct-style loop

Coding prompt (pseudocode)

Write pseudocode (does not need to compile) for a ReAct-style agent loop that alternates between reasoning and actions.

Requirements

• The agent receives a user question.
• On each iteration, the model produces something like:
  • Thought: internal reasoning about what to do next
  • Action: the name of a tool to call (e.g., Search, Calculator, LookupDB) or Finish
  • ActionInput: arguments for the tool
• If an Action is chosen:
  • Call the tool, obtain an Observation.
  • Append Observation back into the context for the next iteration.
• Stop when the model chooses Finish or when a maximum number of steps is reached.
• Include basic safeguards:
  • max steps / timeouts
  • handling tool errors
  • preventing infinite loops

Deliverable

Provide the loop structure and the data you keep in state (e.g., conversation history, scratchpad, tool outputs).
