The agent wasn't the hard part A developer's post-mortem of an AI agent project reveals that most bugs were in the plumbing and configuration rather than the AI itself. The developer highlights issues such as fabricated proof points from config files, a true but useless Blur hook, and four bugs between job queuing and execution, noting that some failures looked like success, including twenty green ticks with zero posters and claimed but unbuilt Cloud Trace. The angle is that almost every real bug was in the plumbing or the config rather than the AI, and several looked exactly like success: the fabricated proof points that came from your own config file, the Blur hook that was true and sourced and useless, four bugs living between "a job is queued" and "a job runs", twenty green ticks with zero posters, and Cloud Trace I'd claimed rather than built. That's an honest post rather than a marketing one, which is why it's worth reading.
