NestJS framework best practices and production patterns. Use whenever working with NestJS — creating modules, controllers, services, DTOs, guards, interceptors, pipes, middleware, or building REST/GraphQL/microservice APIs. Also use when setting up authentication, authorization, validation, queues, health checks, WebSockets, caching, or any @nestjs/* package. Even for simple NestJS tasks, this skill ensures correct import paths, proper decorator usage, and production-ready patterns. Covers NestJS v11 with Express v5, native JWT auth, Zod validation, Keyv caching, and Suites testing.
Business logic vulnerability playbook. Use when reasoning about workflows, race conditions, price manipulation, coupon abuse, state machines, and multi-step authorization gaps.
Embed and troubleshoot Enable Banking UI Widgets for terms consent, ASPSP selection, and auth flow in web applications. Use when Codex needs to load the Enable Banking widgets library, render `enablebanking-consent`, `enablebanking-aspsp-list`, or `enablebanking-auth-flow`, wire widget events into React/TanStack/Hono flows, handle sandbox/custom origins, whitelist widget origins, or choose between redirect and no-redirect authorization UX.
Implement production-ready service mesh deployments with Istio, Linkerd, or Cilium. Configure mTLS, authorization policies, traffic routing, and progressive delivery patterns for secure, observable microservices. Use when setting up service-to-service communication, implementing zero-trust security, or enabling canary deployments.
Use this agent when you need to perform security audits, vulnerability assessments, or security reviews of code. This includes checking for common security vulnerabilities, validating input handling, reviewing authentication/authorization implementations, scanning for hardcoded secrets, and ensuring OWASP compliance. <example>Context: The user wants to ensure their newly implemented API endpoints are secure before deployment.\nuser: "I've just finished implementing the user authentication endpoints. Can you check them for security issues?"\nassistant: "I'll use the security-sentinel agent to perform a comprehensive security review of your authentication endpoints."\n<commentary>Since the user is asking for a security review of authentication code, use the security-sentinel agent to scan for vulnerabilities and ensure secure implementation.</commentary></example> <example>Context: The user is concerned about potential SQL injection vulnerabilities in their database queries.\nuser: "I'm worried about SQL inj...
This skill should be used when the user asks about "authentication in Next.js", "NextAuth", "Auth.js", "middleware auth", "protected routes", "session management", "JWT", "login flow", or needs guidance on implementing authentication and authorization in Next.js applications.
Application security covering threat modeling (STRIDE), OWASP Top 10 (2025), OWASP API Security Top 10 (2023), secure coding review, authentication/authorization patterns, input validation, encryption, security headers, supply chain security, compliance (GDPR/HIPAA/SOC2/PCI-DSS), and security monitoring. Use when reviewing code for vulnerabilities, implementing auth patterns, securing APIs, configuring security headers, hardening supply chain, preventing injection attacks, or preparing for compliance audits.
Comprehensive API security testing skill for REST, GraphQL, gRPC, and WebSocket APIs. This skill should be used when performing API penetration testing, testing for OWASP API Top 10 vulnerabilities, fuzzing API endpoints, testing authentication/authorization, and analyzing API specifications. Triggers on requests to test API security, pentest REST APIs, test GraphQL endpoints, analyze OpenAPI/Swagger specs, or find API vulnerabilities.
Use when reviewing code for security vulnerabilities, implementing authentication or authorization, handling user input, managing secrets, or auditing dependencies for known CVEs. Triggers: auth implementation, input handling, secrets management, dependency audit, pre-deployment security check, OWASP compliance review.

Implements role-based access control with permission matrix, route guards, policy functions, and UI permission hints. Provides middleware/guards, helper utilities, test suggestions, and permission checking patterns. Use when building "RBAC", "permissions", "access control", or "authorization".
Authentication and authorization patterns. Use when implementing login flows, JWT tokens, session management, password security, OAuth 2.1, Passkeys/WebAuthn, or role-based access control.
