Introduction
This workflow template automates the code review process for new GitHub pull requests. It uses an AI model to analyze code changes, cross-reference relevant project markdown files for guidelines, and generate a comprehensive review comment.
It performs three key tasks:
- Listens for pull request events via a webhook.
- Extracts and prepares key pull request information.
- Uses an AI agent to review the changes and related documentation, then posts a detailed review comment back on the pull request.
What you need
- A GitHub account with repository access.
- A Needle connector configured with your GitHub account and permissions.
- An AI model available on the Needle platform.
How the flow works
| Node | Function |
|---|---|
| Webhook Trigger | Captures incoming GitHub pull request events to start the workflow. |
| Parse PR Info | Extracts critical details such as repository owner, repo name, pull request number, title, description, action type, and branch name from the webhook payload. |
| AI Code Reviewer | Retrieves the pull request diff, scans the repository for markdown files, analyzes code changes against documentation, and posts a comprehensive review comment back to GitHub. |
AI Review Process
The AI model conducts a thorough assessment by performing the following actions:
- Retrieves the diff of the pull request to view code changes.
- Scans the repository for all markdown files and reads their content to understand project guidelines.
- Analyzes code changes for quality issues, security concerns, and best practices.
- Composes a formatted pull request review comment highlighting positives, issues with severity levels, and documentation update needs.
- Posts the review comment directly to the GitHub pull request.
Output
At the end of the workflow, a detailed AI generated review comment will be added to the GitHub pull request, helping maintainers quickly understand the quality and impact of the proposed changes.
Notes
- Ensure your GitHub connector has permission to read pull requests and post reviews.
- The AI agent relies heavily on the presence and quality of markdown documentation to provide precise feedback.
- Customize the AI prompt if you want to adjust review criteria or tone.
