The skill adds AWS-specific provider-aware logic including AWS4 icon support, icon availability checks, fallback mappings, and readability defaults like left-to-right flow and minimal crossing lines. Rather than treating AWS as a cosmetic add-on, the skill integrates AWS naming conventions and rendering assumptions to produce cleaner first drafts. Two example outputs are shown: a three-tier PaaS web app and an ECS Fargate multi-tier architecture. The workflow still expects engineers to refine the generated diagrams, but shifts effort from manual layout to architectural clarity. ## Full article daily.dev links to this article rather than hosting it.
