Show HN: CodeRLM – Tree-sitter-backed code indexing for LLM agents

**Show HN: CodeRLM – Tree-sitter-backed code indexing for LLM agents**

I've been building a tool that changes how LLM coding agents explore codebases, and I wanted to share it along with some early observations.Typically claude code globs directories, greps for patterns, and reads files with minimal guidance. It works in kind of the same way you'd learn to navigate a city by walking every street. You'll eventually build a mental map, but claude never does - at least not any that persists across different contexts.The Recursive Language Models paper from Zhang, Kraska, and Khattab at MIT CSAIL introduced a cleaner framing. Instead of cramming everything into context, the model gets a searchable environment. The model can then query just for what it needs and can drill deeper where needed.coderlm is my implementation of that idea for codebases...
