Worked on enhancing reliability and flexibility across backend systems, focusing on two repositories: Hermes Agent and Oh My Pi. Addressed a streaming workflow issue in Hermes Agent by updating the stream finalization logic, ensuring streams are properly closed when a 'done' signal is received, which reduces operational risk and improves stability. In Oh My Pi, generalized the web search tool prompt by removing model-specific references, making prompts adaptable to any AI model and supporting broader use cases. Utilized Python and Markdown for implementation, applying backend development and prompt engineering skills to deliver targeted improvements with clear commit-level traceability.
