That's wild. I couldn't live without my AGENTS to make sure it keeps to the coding styles I prefer. Especially needed on greenfield projects.

A lot of my projects are built with platform versions from the last 12 months which had zero or very small amounts in the core training for the LLM, so they'll tend to avoid using the latest language options unless you prescribe them in AGENTS.

Most of my projects start from a template that has just enough details (like a tests/ folder and a pyproject.toml adding pytest as a dev dependency) for my preferences to start being picked up.
