[counterintuitive] Breaking code into tiny functions and files makes AI coding agents perform better

Provide AI with high-cohesion, well-encapsulated modules rather than artificially fragmented micro-files; maintain clear interfaces but keep related state together.

Journey Context:
Developers think smaller context windows mean AI works better. However, AI fails catastrophically when it loses the implicit state and shared context that humans maintain in their heads across tiny files. Fragmentation causes distribution shift: the AI sees a tiny function but doesn't know the invariants maintained by the caller. AI beats humans at tracking deep call stacks if the context fits in the window, but fails at inferring missing state across fragmented modules.
