Show HN: Multi-Agent Code ReviewHey HN! We’re Oliver Gilan & Ben Warren and today we’re launching Mesa (https://mesa.dev) into public beta to help large engineering teams review code more effectively.There are plenty of code review agents that exist but we found that they fall short in a number of ways. They don’t…- Let you tailor the reviews with enough fidelity- Give you control over the models used. If a new foundation model is released I might want to try it!- Align the costs effectivelyMesa solves these problems with a multi-agent architecture where you define custom review agents that specialize in reviewing certain dimensions of your codebase. This allows you to finely control the review quality and receive reviews that are aware of specific dependencies, business logic, a specific domain in your codebase, or anything else you care about.You can control the model a specialist uses which is great for trying newly released models but also for controlling costs. When a change is made to our database schema, we ha
