Worked on the Shopify/cli repository, focusing on resolving a targeted bug related to UI Extensions module import paths. Addressed an incorrect import reference by updating the CLI app package from '@shopify/ui-extension' to '@shopify/ui-extensions', ensuring that both the main logic and associated tests for extension type generation referenced the correct module. The fix was implemented in a single, low-risk commit to maintain release stability and minimize disruption. Utilized full stack development skills with a focus on JavaScript and TypeScript, aligning the codebase and test suite to prevent future regressions and support ongoing development of extension generation features.
