Worked on the Kotlinx.coroutines repository to improve contributor documentation and streamline the API validation process. Focused on updating the CONTRIBUTING.md file, the work clarified the correct command for validating the Kotlin Gradle Plugin ABI during public API dumps, addressing confusion caused by outdated apiDump references. Using Markdown and leveraging knowledge of contribution guidelines, the changes enhanced onboarding for new contributors and reduced CI failures related to API stability checks. By aligning documentation with the latest Gradle plugin ABI tooling, the update improved reproducibility and accuracy in API validation workflows, supporting a more consistent and reliable contributor experience for the project.
