What is Graphite Agent?
Graphite Agent, formerly launched as Diamond, is an AI-powered code review tool from Graphite, an Anthropic-backed developer productivity company. It delivers instant, high-signal feedback on every pull request, catching logic bugs, security vulnerabilities, performance issues, style inconsistencies, and documentation gaps before code reaches production.
Built to understand the full context of a repository, it is designed for engineering teams that want to speed up review cycles without drowning developers in low-value comments, advertising a low negative or false-positive comment rate.
The tool integrates directly with GitHub so reviewers stay in their existing workflow, offers one-click fixes for flagged issues, and lets teams enforce their own conventions through custom rules written in plain language as well as popular style guides such as OWASP, Airbnb, Google, and PEP.
It sits within the broader Graphite platform, which also provides stacked pull requests and merge tooling, and it has expanded to incorporate capabilities like cloud coding agents.
Typical use cases include automating first-pass reviews, enforcing security and quality standards across many repositories, and reducing reviewer burden on busy teams. Strengths include fast turnaround, a deliberately low false-positive rate, easy one-click setup with no config files, and tight GitHub integration.
Limitations are that it is most valuable inside the GitHub-centric Graphite ecosystem and that pricing for the full platform is geared toward teams rather than individuals. It uses a freemium and subscription model with free trials and enterprise options.
Pricing changes often, so check the official site for current plans.
