Worked on the FoundationAgents/OpenManus repository to address a dependency conflict that was impacting build stability. Focused on dependency management using Python, the developer resolved the issue by pinning the pydantic_core package to version 2.27.2 and tightening the upper bound in setup.py to prevent future incompatibilities. This approach restored compatibility and ensured that continuous integration pipelines could run without interruption. All changes were carefully documented in the commit history to support future maintainability. No new features were introduced during this period, as the primary effort centered on stabilizing the codebase and maintaining reliable builds through precise dependency control.
