User says GPT 5.6 over-plans, invents tests, and burns tokens in coding work

A Reddit user says GPT 5.6 became hard to use for coding because it kept inventing tests, over-planning, and chasing rabbit holes.
- The complaint is not about raw capability, but about workflow behavior: too much procedural overhead, unnecessary smoke tests, and token waste.
- The user ended up signing up for Claude just to make Codex “shut up” and stick to the basics.
- The post is a concrete example of a common agentic-coding failure mode: the model keeps optimizing the process instead of finishing the task.
