Accelerate your code review process without sacrificing quality. This workflow analyzes every new GitHub pull request with AI, identifies potential bugs and improvements, checks for code standards compliance, and posts helpful review comments so developers get immediate feedback.
Receive pull request event from GitHub
The workflow triggers when a pull request is opened, updated, or marked ready for review. It fetches the PR description, changed files, diff content, and any linked issues to understand the full context of the changes.
Analyze code changes with Claude
Using Claude, the workflow analyzes the code changes looking for potential bugs, security vulnerabilities, performance issues, and code style problems. The AI understands the context of surrounding code and the PR's stated purpose.
Generate review comments and suggestions
The AI generates specific, actionable review comments for each issue found. Comments include the problem identified, why it matters, and a suggested fix. The tone is constructive and educational rather than critical.
Post review comments to GitHub PR
Review comments are posted directly to the GitHub PR as inline comments on specific lines of code, plus an overall summary comment. The review can be configured to request changes, approve, or just comment based on severity.
Notify team in Slack about review
A notification is sent to Slack summarizing the AI review findings with a link to the PR. This ensures developers see the feedback quickly and can address issues before human reviewers spend time on the same problems.
Why automate code review with AI?
Code reviews are essential for quality but create bottlenecks. Senior developers spend hours reviewing code, and PRs sit waiting for attention. AI code review provides instant feedback on common issues, freeing human reviewers to focus on architecture and design.
Get immediate feedback on every PR
Instead of waiting hours or days for a reviewer, developers get AI feedback within minutes. This tightens the feedback loop and helps catch issues while the code is fresh in mind.
Catch common issues automatically
AI excels at spotting patterns: null pointer risks, SQL injection vulnerabilities, missing error handling, and code style violations. These checks happen consistently on every PR without reviewer fatigue.
Free senior developers for high-value review
When AI handles the routine checks, human reviewers can focus on what matters most: architecture decisions, business logic correctness, and mentoring junior developers.
How to set up AI-powered PR reviews
Setting up this GitHub review workflow takes about 15 minutes. You'll connect your repository, configure review rules, and customize the feedback style.
What you need to get started
- GitHub repository with webhook access
- Claude API key for code analysis
- Slack workspace for notifications
- Defined code standards and review criteria
Configuring review rules
- Specify which file types and directories to review
- Define severity levels for different issue types
- Set rules for when to request changes vs. just comment
- Configure any project-specific patterns to check
Customizing AI review behavior
- Provide your team's coding standards and style guide
- Define what security patterns to flag
- Specify any domain-specific rules or conventions
- Set the tone and detail level for comments
Frequently asked questions about AI code review
Will AI replace human code reviewers?
No, AI augments human reviewers rather than replacing them. AI catches routine issues while humans focus on design, architecture, and mentoring. The best results come from combining both.
How accurate is AI at finding real bugs?
AI is quite good at identifying potential issues but may flag false positives. Configure severity levels so developers know which comments are high-confidence versus suggestions to consider.
Can the AI understand our codebase context?
The AI analyzes each PR with surrounding code context. For even better results, you can provide documentation about your architecture and conventions to improve relevance.
What languages does AI code review support?
AI can review code in most popular languages including JavaScript, TypeScript, Python, Go, Java, Ruby, and more. Quality is best for widely-used languages with lots of training data.
