Quoting Kenton Varda
Kenton Varda declared a moratorium against AI-written change descriptions for his team, arguing that AI-generated PR and commit messages outline low-level code details visible in the code itself while omitting the higher-level context needed to understand what the code does broadly.
Background
Kenton Varda is a prominent software engineer, best known as the creator of the Cap'n Proto serialization protocol and the Sandstorm.io platform, and a key figure at Cloudflare (where he led the Workers serverless platform). He's posting about a common problem in modern software development: developers using AI tools (like ChatGPT or GitHub Copilot) to auto-generate commit messages and pull request descriptions. Varda argues these AI summaries are worse than useless because they describe the surface-level code changes (which any reviewer can see by reading the diff) while missing the higher-level intent, design rationale, and context that a human reviewer actually needs. This reflects a growing backlash among experienced engineers against the uncritical use of generative AI in development workflows — the tools produce confident-sounding text that saves the author effort but offloads the cost of poor communication onto reviewers.
