GraphQL Client (Apollo / urql) AI Skill Guide

Overview & Engine Architecture

GraphQL clients (Apollo Client, urql) send typed operations to a GraphQL HTTP (or WS) endpoint, normalize/cache results, and integrate with UI frameworks. Agents write precise operations (no accidental over-fetch), configure auth links/exchanges, pick sane cache policies, and handle partial errors (errors + data) explicitly.

UI hooks/components
   -> Apollo Client / urql client
       -> links/exchanges (auth, retry, HTTP, WS)
           -> GraphQL API
Cache (normalized / document) <- results
