This article provides a comprehensive guide for integrating CodiumAI PR-Agent, an open-source AI tool, with self-hosted Gitea instances to automate code review processes. By leveraging Docker for deployment, developers can configure the system to automatically analyze Pull Requests, generate descriptions, and provide quality suggestions in Traditional Chinese. The integration requires setting up Gitea Personal Access Tokens, OpenAI API keys, and configuring Webhooks to trigger AI analysis on PR events such as 'opened' or 'synchronize'.

Key technical configurations include selecting cost-effective models like 'gpt-4.1-mini', setting the response language to 'zh-TW', and utilizing an ignore list to exclude non-code files (like node_modules and build artifacts) to optimize token usage and reduce costs. While AI cannot fully replace human oversight, this setup significantly streamlines documentation and catches low-level errors, allowing developers to focus on critical logic. The article details the complete workflow from Docker Compose setup to verifying the automated review comments directly in the Gitea interface.
