Ollama PR review action

A GitHub Action that uses an ollama install to review pull request changes and post feedback as a comment.

This is based on the Claude action by Eric Hellman.

Features

• Analyzes code changes in pull requests
• Provides feedback on code quality, potential bugs, security issues, and performance
• Posts the review as a comment on the PR
• Ignores binary files and deleted files

Setup

Prerequisites

Access to an ollama installation which is serving requests via HTTP (i.e. running ollama serve), which already has the models you wish to use (i.e. ollama pull {model_name} has already been executed).

You may wish to set up a self-hosted runner, either on the same machine as ollama, or on the same LAN, to maximise performance.

Usage

Add the following to your GitHub workflow file (e.g., .github/workflows/code-review.yml):

name: Code Review

on:
  pull_request:
    types: [opened, synchronize]

jobs:
  review:
