title: "PlanetScale protects production reliability with Bugbot"
description: "PlanetScale describes code review as the bottleneck created by rapidly increasing agent-generated code, while human review capacity remained fixed. To preserve production reliability, the company adopted Bugbot as a dedicated agentic review layer alongside its existing process. Bugbot surfaces semantic and logical issues that static analyzers, linters, and straightforward frontier-model reviews may miss, including premature completion states, non-converging asynchronous controllers, and database restart edge cases. Across more than 2,000 pull requests reviewed monthly, roughly 80% of Bugbot's comments are addressed before merge. PlanetScale says this prevents potential production downtime, saves the equivalent of two full-time engineers of review effort, and lets engineers focus on complex infrastructure work without sacrificing quality."

**Type:** Problem & solution

## Summary

PlanetScale describes code review as the bottleneck created by rapidly increasing agent-generated code, while human review capacity remained fixed. To preserve production reliability, the company adopted Bugbot as a dedicated agentic review layer alongside its existing process. Bugbot surfaces semantic and logical issues that static analyzers, linters, and straightforward frontier-model reviews may miss, including premature completion states, non-converging asynchronous controllers, and database restart edge cases. Across more than 2,000 pull requests reviewed monthly, roughly 80% of Bugbot's comments are addressed before merge. PlanetScale says this prevents potential production downtime, saves the equivalent of two full-time engineers of review effort, and lets engineers focus on complex infrastructure work without sacrificing quality.

## Context

PlanetScale needed to maintain a high standard of production reliability as code-generation agents increased output. Human review capacity remained fixed, making code review the new bottleneck and creating pressure to dedicate two engineers exclusively to reviewing code.

## Approach / What changed

PlanetScale added Bugbot as a dedicated agentic review layer alongside its existing process. The tool examines pull requests for deeper semantic and logical problems, and the company measures its review quality through the proportion of identified issues addressed at merge time.

## Takeaways

- Roughly 80% of Bugbot comments are addressed before merge across more than 2,000 pull requests reviewed each month.
- Bugbot identifies issues such as premature completion states, broken critical code paths, non-converging asynchronous controllers, and database restart edge cases.
- PlanetScale estimates Bugbot saves the equivalent of two full-time engineers' review effort while allowing engineers to focus on complex infrastructure work.
