According to GitHub documentation, Rune is an open-source tool that maintains persistent codebase understanding for AI coding agents through Model Context Protocol (MCP), enabling agents to work with codebases without rebuilding context between sessions. The tool continuously maps repositories and exposes queryable evidence-backed understanding of code relationships and structure. Multiple developers report this solves a core limitation where agents like Claude Code lose project context when switching between tasks.
