Worked on enhancing the Knowledge Base Synchronization API within the 1Panel-dev/MaxKB repository by implementing and documenting a required sync_type parameter. This addition allowed API clients to specify synchronization behavior, supporting either replace or complete modes, and addressed integration reliability concerns. The work involved updating both the Python codebase and the associated API documentation to clarify usage and semantics, directly resolving Issue #5081. By aligning code changes with documentation and linking them to a specific commit, the developer ensured consistency and transparency. The focus on API development and documentation improved client integration workflows and established clearer expectations for future contributors.
