Expert Convex backend development for December 2025. Use when (1) Building Convex queries, mutations, or actions, (2) Defining schemas and validators, (3) Integrating Convex with React/Next.js, (4) Implementing authentication with Convex Auth or Clerk, (5) Building AI agents with persistent memory, (6) Using file storage, scheduling, or workflows, (7) Optimizing database queries with indexes, or any Convex backend architecture questions.
Guidelines for implementing OAuth 2.0 and OAuth 2.1 authentication flows with security best practices and PKCE
Framework-agnostic frontend security guide based on OWASP Secure Coding Practices. Covers XSS prevention, CSRF protection, Content Security Policy (CSP), secure cookie configuration, client-side authentication patterns, input validation, secure storage, and security headers. Activates for security audits, vulnerability reviews, or browser security questions in any web application. NOT for backend/NestJS security (use generating-nest-servers). NOT for Nuxt-specific implementation (use developing-lt-frontend).
X/Twitter CLI tool for reading tweets, threads, replies, searching, managing bookmarks, and fetching news/trending topics. Use when the user needs to read tweets, search X/Twitter content, get user timelines, fetch bookmarks, or retrieve trending news from the command line. Supports cookie-based authentication from Safari or Chrome.
Use this skill when building Model Context Protocol (MCP) servers on Cloudflare Workers. This skill should be used when deploying remote MCP servers with TypeScript, implementing OAuth authentication (GitHub, Google, Azure, etc.), using Durable Objects for stateful MCP servers, implementing WebSocket hibernation for cost optimization, or configuring dual transport methods (SSE + Streamable HTTP). The skill prevents 15+ common errors including McpAgent class export issues, OAuth redirect URI mismatches, WebSocket state loss, Durable Objects binding errors, and CORS configuration mistakes. Includes production-tested templates for basic MCP servers, OAuth proxy integration, stateful servers with Durable Objects, and complete wrangler.jsonc configurations. Covers all 4 authentication patterns: token validation, remote OAuth with DCR, OAuth proxy (workers-oauth-provider), and full OAuth provider implementation. Self-contained with Worker and Durable Objects basics. Token efficiency: ~87% savings (40k → 5k tokens). Production tested on Cloudflare's official MCP servers.

Analyze routes and recommend whether to use Server Actions or API routes based on use case patterns including authentication, revalidation, external API calls, and client requirements. Use this skill when deciding between Server Actions and API routes, optimizing Next.js data fetching, refactoring routes, analyzing route architecture, or choosing the right data mutation pattern. Trigger terms include Server Actions, API routes, route handler, data mutation, revalidation, authentication flow, external API, client-side fetch, route optimization, Next.js patterns.
Use when Django REST Framework for building APIs with serializers, viewsets, and authentication. Use when creating RESTful APIs.
Hytale server setup, configuration, and administration. Covers config.json, permissions.json, authentication, port forwarding, hosting options, and going public. Use when setting up a server, configuring permissions, troubleshooting connection issues, or planning server infrastructure.
This skill should be used when the user asks to "generate audit logs", "create HIPAA audit trail", "log healthcare events", "configure audit logging", "track PHI access", "maintain compliance logs", "audit log format", "healthcare event logging", "access control logging", "authentication logging", "HIPAA logging requirements", or mentions HIPAA audit trails, healthcare event logging, compliance logging, PHI access tracking, authentication auditing, or §164.312(b) logging requirements.
Plan and build production-ready FastAPI endpoints with async SQLAlchemy, Pydantic v2 models, dependency injection for auth, and pytest tests. Uses interview-driven planning to clarify data models, authentication method, pagination strategy, and caching before writing any code.
Initial Convex workspace setup in Coder workspaces with self-hosted Convex deployment, authentication configuration, Docker setup, and environment variable generation
Elasticsearch and Elastic APM integration with Serilog structured logging for .NET applications. Use when: (1) Implementing or configuring Serilog with Elasticsearch sink, (2) Setting up Elastic APM with data streams and authentication, (3) Creating logging extension methods in Infrastructure layer, (4) Enriching logs with app-name and app-type properties, (5) Configuring log levels and environment-specific logging, (6) Questions about logging security (PII, credentials), or (7) Troubleshooting observability and monitoring setup.
