How to Build a Code Review Agent
Automate code review with an agent that reads repos, analyzes diffs, checks for security issues, and suggests improvements.
Overview
Code review agents integrate with Git repositories to read pull requests, analyze code changes, identify bugs and security vulnerabilities, and leave actionable feedback. They can enforce coding standards, detect anti-patterns, and even suggest refactoring opportunities. The best setups combine static analysis with LLM-powered reasoning.
💡 Implementation Tips
Focus on security-critical paths first — auth, input validation, data handling
Use filesystem read capabilities to understand full context, not just diffs
Pair with code execution to run tests and linters automatically
Set clear scope — reviewing everything leads to noise
