This GitHub Action leverages Anthropic Sonnet 3.5 to perform automated code reviews, helping maintain high-quality codebases by providing insightful feedback directly within your Pull Requests. This Action can be configured to run on every PR or trigger based on specific labels.

1. Automated Code Review: Reviews code changes in PRs, highlighting potential improvements and issues.
2. Customizable Triggers: Run reviews on every PR or when specific labels are applied.
3. File Exclusion: Optionally exclude files (e.g., configuration files, documentation) using wildcard expressions.
4. Seamless Integration: Works effortlessly with GitHub workflows and supports the latest Anthropic API.

1. Anthropic API Key:
   Sign up at Anthropic and obtain an API Key.
2. GitHub Secrets:
   Add the API Key as a secret in your repository:
   • Go to Settings > Secrets and variables > Actions.
   • Click New repository secret and name it ANTHROPIC_API_KEY.

Here’s how you can set up the Action in your repository:

Create a workflow file (e.g., .github/workflows/code-review.yml) with the following content:

name: 'Code Review'

on: 
  pull_request: # Trigger on pull requests

jobs:
  code-review:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      pull-requests: write
    steps:
      - uses: actions/checkout@v4
      - uses: arpitgandhi9/creview@v0.3
        env:
          NODE_OPTIONS: '--experimental-fetch'
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
          exclude_files: '*.json, *.md, *.yml' # Optional: Exclude files from the review

To trigger the review only when a specific label (e.g., AUTO) is added to a PR, use the following workflow configuration:

name: 'Code Review on Labeled PRs'

on: 
  pull_request:
    types: [labeled] # Trigger when a label is added

jobs:
  code-review:
    if: ${{ contains(github.event.label.name, 'AUTO') }}
    runs-on: ubuntu-latest
    permissions:
      contents: read
      pull-requests: write
    steps:
      - uses: actions/checkout@v4
      - uses: arpitgandhi9/creview@v0.3
        env:
          NODE_OPTIONS: '--experimental-fetch'
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          anthropic_api_key: ${{ secrets.ANTHROPIC_API_KEY }}
          exclude_files: '*.json, *.md, *.yml' # Optional: Exclude files from the review

Exclude specific files from being reviewed using a wildcard pattern.
Example:

• *.md excludes Markdown files.
• config/*.json excludes JSON files in the config directory.

• GITHUB_TOKEN: Default token provided by GitHub for accessing the repository.
• ANTHROPIC_API_KEY: Your Anthropic API Key.

• Fine-tune the Review Scope: Adjust the exclude_files pattern to prevent unnecessary reviews on non-critical files.
• Optimize Workflow: Use label-based triggers to control when reviews occur, saving computational resources.
