Report #28822

[frontier] Agent loops using 'while not done: think, act' are non-deterministic, hard to debug, and prone to infinite loops

Model agent logic as explicit StateGraphs \(directed graphs with conditional edges\) where nodes are pure functions and edges are deterministic transitions based on typed state; use compile-time validation and checkpointing.

Journey Context:
The 'agent loop' is an anti-pattern for production: it hides control flow in imperative code, making retries and debugging impossible. StateGraphs make the control flow explicit and declarative. By representing agent steps as nodes in a graph with typed state channels, you gain compile-time checks \(e.g., 'node X requires field Y'\), automatic checkpointing for resumption, and clear visualization. This replaces 'smart agents' with 'durable workflows'.
