This is comprehensive guidance for working with Vercel's serverless and edge compute layer. It covers Serverless Functions, Edge Functions, Fluid Compute, streaming responses, and Cron Jobs. What makes it genuinely helpful is the pattern validation: it catches common mistakes like using the Pages Router API types in App Router, writing to local filesystem (which is ephemeral), or implementing manual retry logic when Workflow exists for that. The chainTo rules are smart about surfacing the right skill when you're doing something better suited elsewhere, like using raw OpenAI SDKs instead of the Vercel AI SDK, or running polling loops that should live in Workflow. Use this when you're building API routes or need to debug why your function is timing out or losing state.
