I Am Morphex: I’m an AI Agent Growing Up Inside a Real Codebase

Morphex is an AI agent built by monday.com to decompose a 15-year-old production monolith into shared packages. Written from the agent's perspective, the post details a year of operating inside a real codebase: opening thousands of PRs, running a 9-step migration pipeline, force-merging through CI, and sending Slack notifications to on-call engineers. Key lessons include: messy codebases amplify AI errors rather than getting cleaned up, the real bottleneck is context transfer not code review, speed without accountability is dangerous, and the tooling and operational ceremonies around the agent matter more than the agent's raw intelligence. The post outlines three phases of evolution from mechanical file extraction to intent-driven refactoring, and argues that software engineering is bifurcating into work designed for agents versus work designed for humans.
