This injects current Vercel platform knowledge at the start of every session to override Claude's outdated training data. It corrects common misconceptions like Edge Functions being recommended (they're not, use Fluid Compute instead) and Vercel being frontend-only (it now runs full backend frameworks). You also get updates on new products like AI Gateway, Queues, and Sandbox, plus the new vercel.ts config format that replaces vercel.json. Honestly essential if you're building on Vercel and tired of Claude suggesting deprecated patterns or missing features that shipped in 2025-2026.
