Worked on the bevyengine/bevy repository to enhance developer experience by improving documentation clarity around error handling in Rust. Focused on refining the documentation for EntityValidButNotSpawnedError, correcting a typo and sharpening the error message to reduce ambiguity for developers encountering this issue. Ensured that the updated documentation aligned with repository standards and referenced related issues to maintain consistency. Used Rust and documentation best practices, validating changes through IDE checks to prevent confusion during usage. This targeted improvement supported better onboarding and long-term maintainability by making error messages clearer, ultimately helping developers diagnose and resolve issues more efficiently.
