Rust Project Adopts AI Coding Guidelines: LLMs Can Assist but Not Author

The Rust project's five core teams have officially adopted new guidelines for using large language models (LLMs) in contributions to the rust-lang/rust repository. The rules permit LLMs for analysis, review, and translation but prohibit direct generation of code or documentation, with mandatory disclosure of AI involvement. The guidelines aim to balance AI utility with code quality, including a circuit-breaker mechanism to prevent over-reliance.
