Skill UI

Implement secure API design patterns including authentication, authorization, input validation, and protection against vulnerabilities. Covers JWT token contracts, refresh sessions, resource authorization, and input parsing. Suitable for backend developers securing endpoints, preventing abuse, and ensuring data integrity in production environments.

This skill specializes in creating realistic mock services for development, testing, and demonstration purposes. It simulates real API behavior to enable parallel development and facilitate thorough testing. Use it for building mock APIs for frontend or integration testing, simulating partner APIs, creating demo environments, and validating API contracts before backend completion. Avoid using for production systems or security testing.

This skill deploys web applications with backend APIs and storage to a public URL. It supports frontend templates like React and Next.js. Users can deploy new apps or update existing ones via HTTP API calls. The workflow includes retrieving deployment instructions, fetching templates, and checking deployment status. It ensures secure API key management and tracks deployment lifecycle.

Optimize end-to-end application performance using specialized agents for profiling, observability, database/backend tuning, frontend loading, CDN optimization, and load testing. Use when coordinating cross-stack performance improvements, establishing baselines, identifying bottlenecks, and setting up monitoring for sustained reliability.

This skill provides expertise in proven backend architectural patterns, including Clean Architecture, Hexagonal Architecture, and Domain-Driven Design (DDD). It guides users in building highly maintainable, testable, and scalable systems. Use it when designing new services, refactoring complex monoliths, establishing team standards, or planning microservice decompositions. It emphasizes defining clear boundaries and handling complex, durable workflows.

A goal-integrity skill for backend/API/persistence work that preserves existing behavior, validates changes, and prevents scope drift. Emits contracts, deviation notices, and phase checks to maintain alignment with user requirements during complex development tasks. Skip for Q&A or trivial edits.

Product vision and planning package for Auri, a voice assistant built on Alexa with a configured Claude model: persona, AWS stack, Free/Pro/Business/Enterprise tiers, four-phase roadmap, GTM strategy, north star metric and competitive analysis. Planning only, not a deployed backend.

This skill enables building production-ready serverless applications on AWS. It covers core components like Lambda functions, API Gateway, and DynamoDB. It also includes event-driven patterns using SQS and SNS, deployment strategies with SAM or CDK, and optimization techniques for cold starts. Ideal for backend development and cloud-native architecture implementation.

Automate deployment of containerized frontend and backend applications to Azure Container Apps using Azure Developer CLI. Supports remote builds, managed identity, Bicep infrastructure, and idempotent hooks. Ensures secure authorization and environment variable management for production environments.

Python SDK for managing Azure API Management services (APIM). Create/import APIs, products, subscriptions, policies, and backends. Uses Azure Identity for authentication.

This .NET SDK enables developers to manage Azure Application Insights resources for application performance monitoring and observability. It supports creating components, retrieving connection strings, generating API keys, and configuring availability tests via C# code. Ideal for DevOps and backend development workflows involving cloud monitoring.

Expert backend architect for scalable API design, microservices, distributed systems, resilience, security, and observability.
