Assayer

Assayer is open source code review that runs on your machine with your own Codex, Claude Code or OpenCode sign-in. It reviews a pull request, posts its findings inline under your own GitHub login, and can review what you are about to push before you push it. There is no hosted service and no extra API key.

Assayer is alpha. Any 0.0.x release may change behaviour or break a workflow; read the release notes before you upgrade. See VERSIONING.md.

• Getting started: install, sign in, first round.
• How it works: what a round reads, what it can read, and what it posts.
• Engines: Codex, Claude Code and OpenCode.
• Claude Code and Codex: the plugin that lets an agent run Assayer for you.
• Telemetry: exactly what is sent, and how to turn it off.
