Constraint Decay: The Fragility of LLM Agents in Back End Code Generation | Hacker News

Hacker News discussed a study on LLM code generation reliability under multiple constraints.

The findings suggest performance drops as tasks require both correct behavior and adherence to architecture or style.

Commenters said frontier models may do better than the study shows, but agreed that added requirements increase drift.

The takeaway: LLMs handle isolated coding tasks better than complex back-end work with layered constraints.
