A focused reference for n8n contributors who need the house rules at a glance. It covers the TypeScript conventions (unknown over any, satisfies over as), the Vue 3 Composition API setup with mandatory i18n and CSS variables, and the backend patterns like controller-service-repository with dependency injection. The critical rules section is the real value here, especially the updated error handling that steers you away from deprecated ApplicationError. It assumes you're already in the codebase and just need a quick reminder about whether to use Vitest or Playwright, or which package owns what. Points you to the full AGENTS.md files when you need architectural context beyond quick lookups.
