What is PR-Agent?
PR-Agent is an open-source, AI-powered code review agent and a community-maintained legacy project of Qodo. It is a separate project from the Qodo offering for open-source projects. Its tools /describe, /review, /improve and /ask run as comments on a pull request or from the CLI, and /similar_issue finds similar issues in a repository.
The README lists GitHub, GitLab, BitBucket, Azure DevOps and Gitea as git providers, and deployment through the CLI, GitHub Actions, Docker, self-hosted setups and webhooks. Models include OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek and Mistral, plus any other model reachable through LiteLLM. Each main tool uses a single LLM call of about 30 seconds, and a compression strategy handles both small and large pull requests.
Behavior is configured with JSON-based prompting through configuration files. Install it with pip and supply a model key.
