The post argues that architecture enforcement must be machine-readable, not just human-enforced through code review. It introduces ModuleBoundaryKit, a Swift library that declares the module graph once and serves two consumers: a CI validator that fails merges on boundary violations, and an AgentSkillExporter that renders the same graph as a markdown skill file agents can load as context. Key design decisions include requiring explicit dependency declarations (not just layer compliance) and making the exported skill file deterministic so its diff becomes the architecture review. The practical recommendation is to wire the validator into CI, commit the skill file to the agent context directory, and shift review focus to changes in the graph itself rather than scattered import statements. ## Full article daily.dev links to this article rather than hosting it.
