What does Context Rot mean?
What happens when the files, rules, memories, examples, or long conversation history feeding an AI assistant go stale and quietly start making the model worse.
Context rot is stale context. The model may have plenty of information, but some of it no longer matches the code, product, or task.
Origin and usage
Borrowed from software rot and documentation drift, then applied to AI coding assistants, agent memory, and long-context workflows.
