The agents that actually stuck for me do one narrow thing, not everything

After months of building agents, the author concludes that do-everything agents were always brittle—impressive in demos but unusable in practice because it was impossible to tell when they went off the rails. The agents that stuck are embarrassingly narrow: one watches a folder and tags files, one drafts replies to a specific type of email, one summarizes a daily report.

Narrow agents are easy to trust because their behavior is predictable and failures are instantly visible. The author asks others running agents in production: are yours narrow and boring, or have you made a broad one actually hold up?
