In plain words
What is it for?
Use it when implementing user accounts, protected routes, MFA, SSO, passwordless sign-in, passkeys, or social login.

About the project

MoAI-ADK is a Go-based harness that organizes and verifies Claude Code work across planning, implementation, synchronization, and review stages. Developers use it to structure agentic coding tasks, apply quality gates, and route work across language models, while the catalogue entries extend its workflow with skills, hooks, commands, MCP servers, instructions, and settings.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

moai-platform-auth scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Authentication Platform Specialist

Comprehensive authentication and authorization guidance covering three major platforms: Auth0 (enterprise security), Clerk (modern UX), and Firebase Auth (mobile-first).

Quick Platform Selection

Auth0 - Enterprise Security

Enterprise-grade identity platform focused on security compliance and attack protection.

Best For: Enterprise applications requiring strong compliance (FAPI, GDPR, HIPAA), sophisticated attack protection, token security with sender constraining (DPoP/mTLS), multi-tenant B2B SaaS.

Key Strengths: Advanced attack protection (bot detection, breached passwords, brute force), adaptive MFA, compliance certifications (ISO 27001, SOC 2, FAPI), token security (DPoP, mTLS), extensive security monitoring.

Cost Model: Priced per monthly active user with enterprise features at higher tiers.

Context7 Library: /auth0/docs

Clerk - Modern User Experience

Modern authentication with beautiful pre-built UI components and WebAuthn support.

Best For: Modern web applications prioritizing developer experience and user experience, Next.js applications, applications requiring social login with minimal setup, passwordless authentication.

Key Strengths: Drop-in React components with beautiful UI, WebAuthn and passkeys support, seamless Next.js integration, organization management, simple API with excellent DX.

Cost Model: Free tier available, priced per monthly active user with generous limits.

Context7 Library: /clerk/clerk-docs

Firebase Auth - Mobile-First Integration

Google ecosystem authentication with seamless Firebase services integration.

Best For: Mobile applications (iOS, Android, Flutter), Google ecosystem integration, serverless Cloud Functions, applications requiring anonymous auth with upgrade path, small to medium web applications.

Key Strengths: Native mobile SDKs for iOS/Android/Flutter, Google Sign-In integration, Firebase services integration (Firestore, Storage, Cloud Functions), phone authentication, free tier with generous limits.
