During March 2025, Zhengshuli developed two core features across the menloresearch/OpenManus and FoundationAgents/OpenManus repositories, focusing on automation flexibility and resource governance. In menloresearch/OpenManus, Zhengshuli engineered advanced browser configuration options, enabling headless mode, security enhancements, and custom connection settings through Python-based configuration management and browser automation. For FoundationAgents/OpenManus, Zhengshuli integrated token usage limitation by leveraging tiktoken for counting and enforcing input token caps, improving system stability and resource control. The work demonstrated depth in backend development, system integration, and error handling, resulting in more reliable automated workflows and maintainable codebases without introducing new bugs during the period.
