Why use CodeRLM instead of standard grep or file reading?

Unlike grep, CodeRLM is scope-aware and understands the code structure, allowing it to find exact callers and implementations without returning irrelevant text matches or loading massive files into the LLM context.

Does CodeRLM require a separate server?

Yes, the coderlm-server must be running locally to index the project and provide structural data to the Claude skill via the CLI wrapper.

How does CodeRLM save context tokens?

Instead of reading an entire file, CodeRLM extracts only the relevant code block, such as a specific function body or a 20-line range, keeping the prompt focused and efficient.

What languages does CodeRLM support?

CodeRLM currently supports Rust, Python, TypeScript, JavaScript, Go, Java, Scala, and SQL using Tree-sitter parsers.

Developer Tools

Explores and indexes complex codebases using Tree-sitter for precise, context-efficient symbol navigation and dependency tracing.

CodeRLM is a structural code indexing skill that enables Claude to navigate large, multi-language projects without exhausting context limits. By leveraging a Tree-sitter-backed server, it allows for surgical extraction of function implementations, caller tracing, and test discovery across languages like Rust, Python, Go, and TypeScript. This skill is essential for developers who need to reconstruct execution paths, debug error origins, or understand architectural dependencies through targeted queries rather than reading entire files.

Key Features

01Surgical code retrieval of exact function bodies or specific line ranges

02Automated discovery of tests associated with specific functions or symbols

03Deep caller tracing to map execution paths across the entire project

04Multi-language support for Rust, Python, Go, Java, TypeScript, and SQL

05186 GitHub stars

06Tree-sitter-powered indexing for precise symbol and implementation lookup

Use Cases

01Finding relevant unit tests for specific logic to ensure safe refactoring

02Tracing the root cause of an error through a complex, multi-file call stack

03Onboarding to an unfamiliar codebase by mapping symbol relationships and definitions
