Cole Medin has developed an AI second brain that integrates with personal schedules, emails, and tasks, enhancing productivity by anticipating user needs. Built using Claude Code and the Claude Agent SDK, this system operates with simple markdown files and Python scripts. Medin is offering a 4-hour workshop to guide users through the process of building their own AI second brain, along with a livestream demonstration of its capabilities. This initiative highlights the potential for personalized AI tools in everyday productivity.

This release quietly introduces Code Mode, an opt-in feature where Claude writes JavaScript to call its own tools, marking a shift toward more autonomous agent-like behavior within the CLI. The update also hardens the plugin ecosystem by enforcing version ranges and adding strict TypeScript type checking for hooks, which should significantly reduce instability from third-party extensions. Beyond these features, the changelog is dominated by critical fixes for authentication drift in background sessions and memory leaks when handling large files, stabilizing the tool for heavy enterprise use.
This release quietly patches a critical memory overflow in the mtmd module that caused crashes when loading HunyuanVL models. The issue stemmed from F64 position embeddings overflowing an F32 buffer, a subtle bug that broke multimodal inference for users relying on this specific architecture. By enforcing strict F32 requirements, llama.cpp stabilizes support for Tencent's vision-language model without adding new features or changing the core API. It’s a necessary maintenance update that keeps local multimodal workflows from breaking unexpectedly.
