Worked on the openclaw/openclaw repository to enhance the CLI’s reliability by enforcing a minimum Node.js version requirement of 22.12 or higher. Developed fail-fast preflight checks in both the installer and runtime, ensuring that incompatible environments are detected early and users receive clear, actionable error messages. This approach, implemented using JavaScript and Shell scripting, focused on reducing onboarding friction and preventing unsupported deployments. By aligning version management with runtime guards and improving error output, the work improved user experience and reduced support overhead. The changes contributed to more stable deployments and increased confidence in the CLI’s runtime environment across platforms.
