Repomix

Repomix is a command-line tool that packages code repositories into a single file for AI assistants.

Repomix is a command-line tool that packs local or remote repositories into a single file for artificial intelligence tools and models like Claude, ChatGPT, Gemini, and MCP. It formats codebases into XML, Markdown, JSON, or plain text, automatically respecting .gitignore files and using Secretlint to detect credentials. The tool provides token counts for files and repositories to help manage LLM context limits. It is designed for developers who need to share complete repository context for tasks such as code reviews, refactoring, implementation planning, and documentation generation. Users can run it via the command line or Docker, and integrate it with CI/CD workflows using GitHub actions.
