Worked on the Yeachan-Heo/oh-my-claudecode repository to enhance backend stability by addressing a critical bug in the protection logic for OMC and custom skills. Focused on ensuring that only OMC-prefixed skills received protection, the solution prevented custom skills with similar names from being erroneously blocked, thereby improving the reliability of skill execution and session termination. The work involved two targeted fix commits using Node.js and TypeScript, with careful attention to session management and state handling. This update reduced the risk of production outages related to skill-state collisions, reflecting a methodical approach to backend development and codebase reliability.
