Worked on improving the reliability and consistency of the developer portal CLI in the worldcoin/developer-portal repository, focusing on a critical bug fix related to argument order for the Claude MCP setup command. Addressed an issue where server name and endpoint arguments needed to precede configuration flags, ensuring the CLI matched expected syntax and functioned correctly across both legacy and V3 components. This change reduced user errors during setup and streamlined developer onboarding. The work involved cross-component code updates, careful version-controlled patching, and demonstrated proficiency in frontend development, React, and TypeScript, with an emphasis on maintainable CLI design and usability.
