 >If your pull request introduces a large change that materially impacts the work of the CLI or the rest of the repository (e.g., you're introducing new templates, arguments, or otherwise major changes), make sure that it was **discussed and agreed upon** by the project maintainers. Pull requests with large changes that did not have a prior conversation and agreement will be closed.

However, to help the team focus on important issues and features, we will close issues and PRs that are **low-effort AI-generated changes**. If you are submitting an AI generated issue or pull request, please include **concrete test cases**, **scenarios**, and an outline of the **end-to-end developer experience** with your suggested change.
