Introduction to Code Review

Anthropic has introduced Code Review, a new service for teams and enterprise customers that utilizes multiple agents to scan code repositories for unidentified bugs.

With the ability to analyze GitHub pull requests and post findings as inline comments, Code Review aims to catch logic errors, security vulnerabilities, and subtle regressions.

How Code Review Works

A fleet of specialized agents examines code changes in the context of the full codebase, looking for issues that may have been overlooked by human developers.

Reviews are billed on token usage, averaging $15-25 per pull request, depending on size and complexity.

Benefits and Drawbacks

While Code Review has shown positive results, with 84% of automated reviews finding something notable for large pull requests, it may not be the most cost-effective solution for all teams.

However, for organizations that can afford AI tools, Code Review can provide valuable insights and help catch critical issues before they reach production.

Real-World Examples

Anthropic reports that Code Review has been used internally with considerable success, catching issues that human developers may have missed.

Additionally, customers testing Code Review have seen benefits, such as TrueNAS, which used the service to spot a bug in adjacent code that could have erased the encryption key cache.

Conclusion

In conclusion, Anthropic’s Code Review offers a powerful tool for teams looking to improve their code quality and catch critical issues before they reach production.

While it may not be the most cost-effective solution for all teams, it can provide valuable insights and help organizations ensure the reliability and security of their codebases.
