KRouter: Building a Shared Markdown Memory Store in DeepSeek Harness

KRouter is a plugin for DeepSeek Harness designed to address agent context fragmentation and unchecked speculation. Through the MCP protocol, it enables agents such as Claude Code and Cursor to share the same Obsidian vault as a unified memory source. The tool provides local full-text search, a no-guessing mechanism, automated session distillation, and source tracking. All memories are stored as plain Markdown files, ensuring data security and full local control. After installation, users can import historical sessions, allowing agents to accurately reconstruct prior decisions and avoid errors caused by lost context, thereby providing a zero-maintenance “second brain” for development.
