Clerk Authentication
Patterns
Next.js App Router Setup
Complete Clerk setup for Next.js 14/15 App Router.
Includes ClerkProvider, environment variables, and basic sign-in/sign-up components.
Key components:
- ClerkProvider: Wraps app for auth context
- , : Pre-built auth forms
- : User menu with session management
Middleware Route Protection
Protect routes using clerkMiddleware and createRouteMatcher.
Best practices:
- Single middleware.ts file at project root
- Use createRouteMatcher for route groups
- auth.protect() for explicit protection
- Centralize all auth logic in middleware
Server Component Authentication
Access auth state in Server Components using auth() and currentUser().
Key functions:
- auth(): Returns userId, sessionId, orgId, claims
- currentUser(): Returns full User object
- Both require clerkMiddleware to be configured

When to Use
This skill is applicable to execute the workflow or actions described in the overview.
AGI Framework Integration
Adapted for @techwavedev/agi-agent-kit Original source: antigravity-awesome-skills
Memory-First Protocol
Retrieve prior API design decisions, database schema choices, and error handling patterns. Cache API response templates for consistent error formatting.
# Check for prior backend/API context before starting
python3 execution/memory_manager.py auto --query "API design patterns and architecture decisions for Clerk Auth"
Storing Results
After completing work, store backend/API decisions for future sessions:
python3 execution/memory_manager.py store \
--content "API architecture: REST with HATEOAS, JWT auth, rate limiting at 100 req/min per tenant" \
--type decision --project <project> \
--tags clerk-auth backend
Multi-Agent Collaboration
Share API contract changes with frontend agents so they update their client code, and with QA agents for test coverage.
python3 execution/cross_agent_context.py store \
--agent "<your-agent>" \
--action "Implemented API endpoints — 5 new routes with OpenAPI spec and integration tests" \
--project <project>
Agent Team: Code Review
After implementation, dispatch code_review_team for two-stage review (spec compliance + code quality) before merging.
