About RepoAgent

RepoAgent is an open-source, LLM-powered framework for generating documentation for a code repository. It detects added, deleted and modified files in a Git repository, parses code structure through an AST to generate documents for individual objects, and identifies bidirectional invocation relationships between objects to give documentation a broader perspective. It replaces Markdown content as changes occur so documentation stays consistent, and runs generation operations with multi-threaded concurrency. It is positioned as a sustainable, automated documentation update method for team collaboration, and documentation can be displayed as a document book per project powered by GitBook.

It is distributed as the repoagent Python package and can also be run through GitHub Actions. Before configuring parameters, an OpenAI API key must be set as an environment variable on the command line. The repository's stated background focuses on documentation for Python files, such as explanations for each Python file. No pricing information is provided.
