Worked on the nvm-sh/nvm repository to enhance installation reliability and streamline continuous integration processes. Focused on improving the install.sh script by adding ZDOTDIR support for zsh users, which refined NVM profile detection and ensured compatibility across different shell environments. Updated and expanded the test suite using Shell and YAML to validate these changes and address previous test flakiness, resulting in a more robust installation workflow. Enhanced the GitHub Actions CI pipeline by configuring it to trigger urchin tests on pull requests, increasing early quality checks and coverage. Emphasized repository health through clearer commit traceability and ongoing test validation.
