Overview
- The Foundation announced the changes on Tuesday and said it will update contributor rules to forbid autonomous AI agents, 'vibe coding', and AI‑generated substantial code.
- All meaningful code must be human authored while limited AI help such as autocomplete, regex, or find‑and‑replace is allowed only with disclosure in the pull request discussion.
- GitHub submissions created by AI agents already trigger an automatic ban and the Foundation will enforce human review and approval before any merge.
- New contributors with three or fewer accepted PRs will be blocked from submitting major features or refactors without explicit maintainer permission to ensure they learn the codebase.
- The move responds to a surge of low‑effort, AI‑generated pull requests that increased reviewer backlog and morale problems, and it contrasts with more AI‑friendly approaches being pursued by some commercial engine makers.
