How Cloudflare enforces engineering standards using AI

This post introduces the Cloudflare Codex, a system for organizing and enforcing engineering standards. It details the Codex's RFC-based structure, governance model, and lifecycle states (approved vs. enforced). It also describes how Codex statements are extracted and compacted for consumption by AI agents. The post highlights three key consumers of the Codex: the AI code reviewer (which flags violations and blocks merges), the spec reviewer (which evaluates technical designs before implementation), and the incident report reviewer (which assesses postmortems for completeness and quality. It also mentions the development of language-specific linters and a CLI for local AI code reviewer execution.
