What has your coding agent made you worse at, and did you do anything about it?

Handing work to a coding agent changes which skills get used every day. Writing a regular expression from memory might get harder. Reading an unfamiliar codebase without help might feel slower. Holding a large refactor in your head might stop being something you practise. Or it might go the other way, and you read more code than ever, because reviewing the agent's output has become the main job.

The trade can be worth it. Few people miss memorising every flag of a command they run twice a year. But some skills only show their value when the tool is not there: during an outage, in an interview, or when the agent is confidently wrong and you need to see why.

We are curious what this looks like for you:

• Which skill do you think has slipped since you started using an agent daily?
• Which skill has improved, if any?
• Have you done anything on purpose to keep a skill sharp, like turning the agent off for certain tasks?
