Report #24559

[counterintuitive] Why does the LLM lose track of nested loops or deep recursive function calls when writing or tracing code?

Flatten recursive logic into iterative loops when generating code, and limit the depth of nested logical steps in prompts to under 3-4 levels.

Journey Context:
Agents try to trace deep recursion step-by-step in the context. While transformers have a context window, their effective reasoning depth degrades rapidly with nesting. They do not have a call stack. Each recursive step forces the model to attend to the entire previous state, diluting the signal. Flattening to iteration moves the state management to the generated code's runtime, not the LLM's context.
