Designing Deterministic AI Agent Loops: Architecture, Verification, and Replay State Machines
Designing Deterministic AI Agent Loops: Architecture, Verification, and Replay State Machines Most software engineers building with Large Language Models (LLMs) eventually hit the exact same wall: the naive agent loop problem. You start with a straightforward loop: User gives a prompt. LLM selects a tool to call. Runtime executes the tool. Result is appended to context. Repeat until LLM emits a final response. In demos, this works brilliantly. In production, it breaks in infuriatingly subtle wa…
