Vercel
Stack Pack.

Vercel coverage centered on Next.js 15+, the AI SDK, AI Gateway, v0 generation flows, Fluid Compute, and the edge-vs-node decision. Includes opinions on App Router migration, Server Actions, and when to reach for Vercel KV / Postgres vs an external store.

Why it's in the catalog. Vercel's AI surface (AI SDK, AI Gateway, v0) shifted faster than any other vendor in 2025–26. The pack carries the current shape so the frontend architect and AI/ML engineer don't end up wiring last year's patterns.

Headline products and features the pack carries opinions on. Each lives as its own canonical page under stacks/vercel/<product>.md in the etyb-skills repo — currency-stamped, sourced, opinionated.

• Next.js 15+
• AI SDK
• AI Gateway
• v0 (Vercel's gen-UI)
• Fluid Compute
• Edge Functions
• Vercel Postgres / KV / Blob
• Sandbox

When /etyb routes a request to one of these roles AND the Vercel pack is in play, the role's reference is composed with the platform-flavored knowledge from this stack. Same role, sharper answer.

• › system-architect
• › backend-architect
• › frontend-architect
• › devops-engineer
• › ai-ml-engineer

The three things on Vercel that a 2024-cutoff model is most likely to get wrong — and that this pack reflects.

• AI Gateway: provider-agnostic LLM routing with retries, fallbacks, and observability
• Fluid Compute: hybrid edge/node model — pick at function level, no more cold-start tradeoff
• AI SDK v4: streaming + tool-calling + multimodal as first-class primitives

The Vercel pack comes with /etyb — one install, every pack ready to go. The overlay loads automatically when the work calls for it.
