Repoagent

Repoagent is an open-source Python framework with a command-line interface that uses large language models to analyze software repositories and generate or update code documentation. It uses AST analysis to document individual objects, tracks Git file changes, and identifies relationships among code objects to provide repository-level context.

Practical overview

When it fits

Use Repoagent when you want an LLM-assisted documentation workflow for a code repository and can provide an OpenAI API key through the command-line environment.

Who it is for

  • Developers documenting or maintaining a software repository
  • Teams seeking an automated starting point for repository documentation
  • Contributors who want a local Python development setup for the framework

Documented uses

  • Generate documentation for code objects across a repository.
  • Update Markdown documentation as tracked repository files change.
  • Print the hierarchy Repoagent parses for a target repository.
  • Create a documentation draft that developers can verify and refine.
Before you choose

Requirements & limits

The project is open source under the Apache-2.0 license. The README recommends installation with pip and documents an OpenAI API key as a prerequisite for running the tool.

  • The documented primary workflow is a Python command-line tool rather than a hosted web application.
  • The README instructs users to configure an OpenAI API key before configuring Repoagent.
  • The CLI exposes settings for the completion model, temperature, request timeout, and API base URL.
  • The project describes generated documentation as material for developers to verify and fine-tune.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Repoagent and configure its OpenAI key

Prepare the Python package and required API-key environment variable before using the CLI.

Before you start

  • Python package installation with pip
  • An OpenAI API key

Steps

  1. Install the package with the command below.

    Documented command
    pip install repoagent

  2. Set OPENAI_API_KEY in the command-line environment; the README gives commands for Linux/macOS, Windows Command Prompt, and PowerShell.

Expected outcome

The package is installed and the OpenAI API key is configured for the command-line environment.

Guide limitations

  • This setup guide does not cover running Repoagent or generating documentation.
  • The documented setup specifically requires OpenAI API configuration.

Source-based practical guide

Generate or update repository documentation

Run Repoagent from its root directory to generate or update documentation for the target repository.

Before you start

  • Repoagent installed and its OpenAI API key configured
  • A repository available at the target path
  • Access to the Repoagent root directory

Steps

  1. Enter the Repoagent root directory.

  2. Run repoagent run to generate or update documentation.

  3. Optionally add --print-hierarchy to print how Repoagent parses the target repository.

Expected outcome

Repoagent runs its documentation-generation or update workflow; the optional flag prints the parsed repository hierarchy.

Guide limitations

  • The generated documentation requires human verification and fine-tuning, as described in the project background.
