Vercel Functions

This is your Vercel compute layer reference. It covers Serverless Functions, Edge Functions, Fluid Compute, streaming responses, and Cron Jobs. The skill's real value is in the validation patterns: it catches Pages Router types in App Router code, flags direct OpenAI/Anthropic SDK usage (suggesting AI SDK instead), warns when you're writing to the local filesystem or using in-memory caches that won't persist, and spots Express.js imports that won't work in serverless. It chains to workflow guidance when it sees setTimeout polling, and to storage skills when you try filesystem writes. The pathPatterns auto-activate it for api/ folders and route.* files. Helpful if you keep forgetting serverless functions are stateless and ephemeral.
