AI agents suffer "context rot" due to memory degradation, not model limits

AI agents can suffer from "context rot," where their ability to recall and utilize information degrades over time due to factors like compression loss, drift, priority blurring, and noise accretion. This issue is not solved by simply enlarging the context window, as it can defer the problem and even lead to worse performance. Effective solutions involve summarizing information into executable facts, storing memory in a semantic index (like SQLite with embeddings) rather than within a single agent's session, transforming knowledge into on-demand skills, and layering memory by half-life to manage decay and prevent bloat.

    Your Agent Isn't Losing Memory. It's Rotting.

    <p>Agents don't forget because the model is bad. They forget because we built it into them. Six hours and forty messages in, what an agent needs is gone — or still there but wrong, drowned in noise.</p> <p>That's context rot.</p> <p>I've spent the last month inside a team of alwa…
