IMPORTANT: Requires Drizzle ORM or Kysely for D1 - no direct D1 adapter. v1.4.0 (Nov 2025) adds stateless sessions, ESM-only (breaking), JWT key rotation, SCIM provisioning. v1.3 adds SSO/SAML, multi-team support. Use when: self-hosting auth on Cloudflare D1, migrating from Clerk, implementing multi-tenant SaaS, or troubleshooting D1 adapter errors, session serialization, OAuth flows, TanStack Start cookie issues, nanostore session invalidation.
Production-grade API design patterns for REST, GraphQL, gRPC, and tRPC. Covers API architecture, OpenAPI/Swagger specs, versioning/deprecation, authentication/authorization, rate limiting, pagination, error models, contract testing, and developer documentation.
Comprehensive security and authentication workflow that orchestrates security architecture, identity management, access control, and compliance implementation. Handles everything from authentication system design and authorization frameworks to security auditing and threat protection.
Implement secure authentication bridge between Better Auth (Next.js frontend) and FastAPI (Python backend) using JWKS JWT token verification. Use this skill when users need to (1) Integrate Better Auth with FastAPI backend, (2) Implement JWT authentication with JWKS verification, (3) Set up user isolation and authorization in FastAPI endpoints, (4) Configure frontend to send authenticated API requests, or (5) Troubleshoot Better Auth + FastAPI authentication issues.
Secure GraphQL APIs - authentication, authorization, rate limiting, and validation
BibiGPT CLI for summarizing videos, audio, and podcasts directly in the terminal. Use when the user wants to summarize a URL (YouTube, Bilibili, podcast, etc.) or check their BibiGPT authentication status.

Use when setting up, troubleshooting, managing, removing, or checking the health of an Auth0 custom authentication domain (e.g. login.example.com), OR when diagnosing an error (400/403/404/409/429) from the /custom-domains Management API — especially Free-tier 403s (credit card on file, not a plan upgrade), self-managed cert 403s, PATCH-type 400s, `operation_not_supported` on `relying_party_identifier`, and 409 domain-already-exists. Handles CNAME creation in the user's DNS provider (Cloudflare, AWS Route 53, Azure DNS automated; other registrars guided), verification polling, Multiple Custom Domains (MCD), default-domain selection, TLS policy, client-IP header, per-domain passkey relying party identifier, and domain metadata.
