Stop Fixing Broken Architecture: Auto-Enforce Package Boundaries with Cursor Composer and ArchUnit
In 2026, we aren't writing boilerplate anymore; we are directing AI agents to refactor entire modules at once. But if you don't establish automated architectural guardrails, Cursor Composer will happily turn your clean hexagonal architecture into a giant ball of mud in under thirty seconds.
Why Most Developers Get This Wrong
Passive PR reviews: Relying on human reviewers to catch illegal package imports (e.g., domain importing infrastructure) during fast-paced AI code generation is a losing battle.
Static documentation: Writing "architectural guidelines" in Notion that nobody reads, instead of writing executable fitness functions that run in your build pipeline.
