The PR Review Agent automatically reviews every pull request opened in your connected repositories. It analyzes code quality, checks for common security vulnerabilities, enforces your team's style guidelines, and provides actionable suggestions — all before a human reviewer needs to look at it.
How it works
When a pull request is opened or updated, the agent receives a webhook from GitHub and begins its review process:
- Code analysis — The agent reads the full diff and understands the context of changes across your codebase.
- Style enforcement — It checks against your configured linting rules, naming conventions, and architectural patterns.
- Security scanning — Common vulnerability patterns (SQL injection, XSS, hardcoded secrets) are flagged immediately.
- Review comments — The agent posts inline comments on specific lines with clear explanations and suggested fixes.
- Summary — A top-level review comment summarizes the findings with a pass/fail recommendation.
What you need
- A GitHub integration connected to your ZiraLoop workspace
- A Slack integration (optional) for notifications
- A Linear integration (optional) for auto-creating issues from review findings
Configuration
The agent ships with sensible defaults but can be customized:
- Severity threshold — Choose whether to flag only critical issues or include warnings and suggestions
- Auto-approve — Optionally auto-approve PRs that pass all checks
- Custom rules — Add your own review rules using natural language descriptions
- Ignore patterns — Skip files matching certain glob patterns (e.g., generated code, vendor directories)
Who uses this
Engineering teams of all sizes use the PR Review Agent to catch issues early, reduce review cycles, and maintain consistent code quality across their repositories.
