Worked on improving the reliability of Docker sandbox command execution for the openclaw/openclaw repository, focusing on cross-platform compatibility, particularly on Windows systems. Addressed an issue where Windows PATH poisoning disrupted sandboxed commands by modifying the execution flow to skip the PATH variable during docker exec and consistently invoke /bin/sh. This backend development effort, implemented in TypeScript and supported by shell scripting and Docker expertise, enhanced both CI and local development stability. The solution was documented to guide future improvements, ensuring that sandbox-related failures are minimized and that the approach remains maintainable for ongoing cross-platform development and deployment workflows.
