What role do structured Skill files play in making parallel AI development work for maintainability?

Structured Skill files provide Agents with software engineering norms—like naming conventions, layering rules, and module boundaries—so they can internalize most maintainability requirements without human guidance. This allows Agents to produce code with consistent architecture and standards, reducing the need for human architectural oversight during parallel development. However, the article notes that some design trade-offs still escape automated enforcement, so spot-checking key nodes remains prudent.
