As AI coding agents become standard tools in 2025, many engineering teams observe a subtle but widespread pattern: the more features an agent implements autonomously, the less confident developers feel about manually modifying the codebase. This phenomenon, often called intervention paralysis, arises because incremental AI contributions gradually reduce the human maintainer’s mental model of the system. Over time, the growing gap between “what the code should do” and “how it actually works” creates significant psychological friction against refactoring or direct intervention. In this article, I examine the mechanisms behind this erosion of ownership and present a practical mitigation strategy used successfully at scale: scheduled human-led refactoring checkpoints combined with component-level agent sandboxing. The approach is straightforward. Pause new feature work after every n AI-added capabilities, invest m focused day in architectural cleanup, and thereafter restrict agent prompts to single, well-bounded modules.
