Han Xu developed and maintained core features for the AIGNE-io/aigne-framework and blocklet/media-kit repositories, focusing on robust data transformation, documentation publishing, and accessibility improvements. He implemented schema transformation using JSONata and TypeScript, enabling flexible data integration, and introduced multilingual documentation pipelines with enhanced navigation and advanced guides. Han streamlined publishing workflows by automating asset uploads, board management, and cache control for AI model prompts, leveraging Node.js and React for full stack solutions. His work included targeted refactoring, code removal, and dependency management, resulting in cleaner codebases, reduced maintenance overhead, and improved user experience for both developers and end users.

December 2025: Implemented cross-model prompt caching across OpenAI, Gemini, and Anthropic with cache control and UI-visible statistics to improve latency and reduce token costs. Updated core components to support caching metrics and display them in the UI, enabling operators to monitor cache effectiveness and usage. The work is documented in commit 46c628f180572ea1b955d1a9888aad6145204842 (feat: add prompt caching for OpenAI/Gemini/Anthropic and cache token display (#838)).

October 2025: Delivered Gemini image model configurability and a documentation publishing pipeline with multilingual support for AIGNE-io/aigne-framework. The Gemini update adds the imageConfig parameter and updates core dependencies (@arcblock/did-connect-react, @blocklet/did-space-react, and @google/genai) to the latest versions, enabling richer configuration options and ensuring compatibility with updated libraries (commit 252de7a10701c4f5302c2fff977c88e5e833b7b1). The docs pipeline introduces translations, doc-smith config, updated sidebar navigation, and comprehensive guides on advanced topics (YAML-defined agents, prompts, hooks, streaming, and agent types) to improve structure, accessibility, and global onboarding (commit ab34a09ba3bd89fa93889d0e3f22986627d91a7a).
