What is it?

GenAI Code Review runs as a GitHub Action on pull requests. It sends the diff to an LLM (OpenAI, Anthropic, Google Gemini, or any OpenAI-compatible server) and posts inline comments on the PR. It needs only one workflow file and no checkout step, since it reads the pull request over the API.

The project is built around a comment budget. By default it posts the top 5 findings ranked by severity and confidence, and its summary states how many findings were held back and lists them. Findings already raised on earlier pushes are filtered out before ranking, and lockfiles, generated code and similar files are skipped by default. The summary also lists files that were not reviewed, such as oversized or truncated ones.

The action supports an optional panel mode that runs two providers over the same diff and merges their findings, marked as experimental. Run logs record tokens, estimated cost, latency and posted versus suppressed findings. A separate read-only command reports how reviewers responded to the comments.

Key features

  • 01Supports OpenAI, Anthropic, Google Gemini and OpenAI-compatible endpoints such as Ollama or vLLM.
  • 02Posts the top few findings as one grouped inline review, with a sticky summary comment.
  • 03Reports how many findings were suppressed and what files were not reviewed.
  • 04Skips lockfiles, vendored and generated files by configurable glob patterns.
  • 05Writes a JSON run log with tokens, cost, latency and findings.
  • 06Treats diff content as untrusted and validates model output against a schema.

Use cases

  • Adding an automated first-pass review to every pull request in a team repository.
  • Running reviews against a self-hosted model so code never leaves your infrastructure.
  • Keeping review noise low so human reviewers still read the bot's comments.
  • Tracking the cost and latency of LLM reviews across pushes.
