What problem does it solve? Make Apps need a consistent, secure authentication layer for unified login and authenticated /api/make requests, and hand-rolled auth code often breaks cookies, redirects, sessions, or Service-fronted proxy contracts. This Skill provides the rules, references, and audit tooling to generate and review correct auth integration with @qfeius/make-app-auth. ## Core Features & Use Cases - Unified Login Integration: Generates SDK bootstrap with unifiedLogin, apiAuthRedirect, and auth.init redirect flows, including recoverable state_expired/challenge_expired handling and logout wiring. - Service-Fronted Proxy Contracts: Defines the UI -> Service -> make-gateway chain, including /api/make/auth/** and /api/make/oauth/** namespace proxies, cookie forwarding, X-Forwarded-Host/Proto handling, and session/complete redirect preservation. - Deterministic Contract Auditing: Ships scripts/audit-auth-contract.mjs to detect raw fetch usage, token-mode drift, missing auth proxies, local-preview shadowing, and SDK version violations before publish. - Use Case: When generating a new Make App with a Service layer, use this Skill to wire unified login, route all business calls through a shared auth.api adapter, and run the audit script to verify publish readiness. ## Quick Start Use the make-app-auth skill to add unified login and authenticated Make API requests to my generated Make App project.
