Code Review Agent
Your PRs get deep, contextual review for security vulnerabilities, performance issues, and Rails best practices. Everything gets caught before it hits production. Not after.
Here's What's Really Happening
Your senior devs are drowning in PR reviews. Every review takes 30+ minutes. And half the feedback? The same stuff every single time:
- "Missing eager loading" — same N+1 patterns, over and over
- "Add authorization" — Pundit policies forgotten again
- "This should be a service object" — fat controllers everywhere
- "Tests?" — coverage gaps that keep slipping through
Meanwhile, the subtle security issues and architectural drift go completely unnoticed. Why? Because your reviewers are exhausted from catching the same basic mistakes.
How the Agent Works
Six focused passes. Each one catches what humans miss when they're tired.
Context Analysis
First, the agent figures out what this PR is actually trying to do. No blind reviewing.
- → Reads PR description, linked issues, and commit messages
- → Identifies related files and existing patterns in your codebase
- → Maps the change scope: models, controllers, views, tests affected
Security Audit
This is the scary one. OWASP vulnerabilities specific to Rails. The stuff that keeps CTOs up at night.
- → SQL injection, XSS, CSRF, mass assignment vulnerabilities
- → Missing authorization checks (Pundit, CanCanCan)
- → Exposed secrets, insecure direct object references
Performance Analysis
Database and memory issues. The kind that don't show up until you have 10,000 users.
-
→
N+1 queries and missing
includes - → Missing database indexes on foreign keys and query columns
- → Operations that should be background jobs
Architecture Review
Rails conventions and your team's patterns. Consistency matters more than most people think.
- → MVC separation: thin controllers, business logic in models/services
- → RESTful routes and proper use of concerns
- → Consistency with patterns already in your codebase
Test Coverage Check
New code needs tests. But which tests? And are they actually testing the right things?
- → Maps new code to test files, flags missing coverage
- → Identifies untested edge cases and error paths
- → Warns about flaky test patterns before they cause pain
Actionable Feedback
Comments go directly on your PR. Specific suggestions, not vague complaints.
- → Inline comments with code examples showing the fix
- → Issues prioritized by severity: critical, warning, suggestion
- → Explains why, not just what—so your devs actually learn
What It Catches
The stuff that's expensive to fix in production but cheap to fix in a PR.
Security Vulnerabilities
SQL injection, XSS, missing auth, exposed credentials
Performance Issues
N+1 queries, missing indexes, memory bloat
Architecture Drift
Fat controllers, misplaced logic, broken conventions
Test Gaps
Missing coverage, untested edge cases, flaky patterns
Style Violations
Inconsistent naming, complex methods, poor readability
Rails Anti-patterns
Callbacks abuse, STI misuse, scope pollution
Let Me Be Clear About What This Isn't
- ✗ Not a linter. Rubocop handles syntax. This handles architecture, security, and context.
- ✗ Not auto-approve. The agent comments, your team decides. You stay in control.
- ✗ Not generic AI. Built for Rails patterns, not generic code suggestions that miss the point.
- ✗ Not a replacement for senior review. It catches the repetitive stuff so your seniors can focus on design and mentoring.
What You Can Expect
Real numbers from teams using this. Your mileage may vary, but this is typical.

Let the agent handle the repetitive review work. Your seniors focus on mentoring and architecture—the stuff that actually needs a human brain.
