Coding agents are moving from sloppy mistakes to over-engineering, and scope creep is the new failure mode

- A coding-agent observer says models are moving through the same arc as software engineers: first they make silly mistakes, then they over-engineer everything.
- The current failure mode is scope creep: agents now get lost in irrelevant details instead of skipping important ones.
- The post points to a small sign of progress in Sol: the model is starting to show the judgment needed to know when code is unnecessary.
- The overall takeaway is that coding agents are improving, but the next leap is not raw capability — it is better judgment and restraint.
