During March 2026, Zkqiang developed a configurable domain option for the Feishu channel in the bytedance/deer-flow repository, enabling seamless international Lark platform integration. By parameterizing the domain, Zkqiang addressed connectivity issues caused by domain mismatches, allowing support for both open.feishu.cn and open.larksuite.com. The solution involved updating both the API and WebSocket clients, as well as revising configuration files and documentation to guide users through international deployment. Utilizing Python, YAML, and asynchronous programming, Zkqiang delivered a focused backend enhancement that resolved a specific integration challenge and improved the flexibility of the system’s configuration and onboarding process.
