A pull request arrives with thirty seven changed files, polished comments, and a description that explains the architecture with unusual confidence. The reviewer approves it. Two days later the team finds the bypassed authorization rule. Nothing looked careless. That was part of the problem.
Within a month there are several teams, several tools, several permission models, and several definitions of done. Management asks how much faster engineering has become. Nobody can say, but the token dashboard is exceptionally detailed.
The team called this agent unpredictability. The ticket was six words long.
A coding agent did not fail to read the documentation. The repository stopped producing documentation years ago. Apparently, intelligence was expected to compensate for archaeology.
Cost is an architectural property, not a billing surprise. Treat your agent as a metered process, or a few sessions will eat a month of budget in a week
All green. All wrong..
