Your AI agent is probably doing too much.
We call it the "Pareto Cut" - a way to stop a small fix from becoming a full rebuild. When an AI coding agent overbuilds the simple stuff, a 5-min fix turns into 20 min.
The fix: find the 20% of the work that creates 80% of the outcome.
On a small task, overbuilding wastes 15 minutes. On a larger build (especially one running autonomously overnight) every unnecessary decision compounds, leaving a mess to clean up in the morning.
Your agents might want to reinvent the wheel. But it's often best fixing/hardening the existing system.
