Maintainers Reject Low-Quality AI Pull Requests

This week tldraw maintainers announced a new contributions policy to automatically close external pull requests after an influx of low-quality AI-generated PRs. The maintainer reports formally correct but context-free diffs, increased PR volume, and QA friction, arguing AI tools have lowered implementation cost while raising noise. The change aims to preserve contextual knowledge and require better contributor vetting to keep meaningful open-source contributions.
