Hey @ArrivedAditya, could you [upload your code to GitHub](https://docs.codecrafters.io/features/publish-to-github) and share the link? It will be much easier to debug if I can run it directly. ---

Added github link below. [https://github.com/ArrivedAditya/claude-code-challenge](https://github.com/ArrivedAditya/claude-code-challenge) I don’t think it will be helpful considering that error I am getting from Openrouter which serves the model. ---

@ArrivedAditya Looks like the tool message has included an unknown field “status”: ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/3X/7/b/7b370db9628851ca2892f6366020daf6b39c549b.png) ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/3X/a/7/a79e201e023248586a9ec9cbd4907f9b05deb8fe.png) ---

Thanks. The error was solved and I was able to complete the write tool section. ---
