Developed cross-platform Windows command shell support for Codex hooks in the tirth8205/code-review-graph repository, focusing on enhancing compatibility and reliability for Windows environments. The work involved updating the hook generation logic to include Windows-specific command configurations and ensuring correct execution using cmd.exe syntax. Leveraging Python, Git, and Windows Shell scripting, unit tests were added to verify the new functionality and maintain robust CI workflows. This feature addressed previous execution issues on Windows, enabling git hooks to function consistently across platforms. The approach emphasized maintainability and thorough testing, resulting in a more seamless developer experience for teams working on Windows systems.
