GitHub is exploring new repository-level controls that would let maintainers disable pull requests entirely or restrict them to collaborators. The move responds to growing complaints about low-quality contributions, including abandoned PRs and AI-generated code that fails to meet project standards.

Maintainers currently waste time reviewing submissions that violate guidelines or offer no real value. Some projects already use custom automations to close unwanted PRs. GitHub’s proposed short-term fixes include UI options to delete spam PRs and settings to block external contributions on a per-repo basis.

Longer-term, GitHub is considering AI-assisted triage tools and enhanced permission models. These could automatically flag PRs that don’t align with project rules or detect AI-generated content. The company is also weighing ways to let maintainers define acceptance criteria before PRs can be opened.

Community feedback will shape which features move forward. Some developers have suggested configurable AI detection thresholds, though early input suggests only 10% of AI-generated PRs are actually useful.
