Egonex-AI/Understand-Anything at 76,789 stars turns any codebase into an interactive knowledge graph.

The TypeScript project compiles a repository into an explorable, searchable graph you can ask questions against, with the explicit framing "graphs that teach beat graphs that impress." It targets Claude Code, Codex, Cursor, and Copilot. Directly relevant if your agent currently greps a few hundred files to answer structural questions, because the graph is the index it should be reading instead. I run a homegrown version of this on my own repo and the difference in agent navigation quality is not subtle.
