Routes AI requests through Vercel's unified gateway so you can switch between 100+ models from OpenAI, Anthropic, Google, and others without juggling provider SDKs. Uses simple "provider/model" strings like "openai/gpt-5.4" or "anthropic/claude-sonnet-4.6" and handles failover, cost tracking, and load balancing with under 20ms overhead. The skill catches outdated model names (it'll nudge you from gpt-4o to gpt-5.4) and enforces proper slug formatting with dots for versions, not hyphens. Authentication defaults to OIDC via vercel env pull, which auto-rotates tokens so you're not managing API keys manually. Worth using if you're already on Vercel or want provider flexibility without rewriting integration code.
