Skill UI

This skill initiates a full-quality automated development pipeline for complex tasks spanning multiple files or replacing frameworks. It generates specifications with acceptance criteria, executes code, and verifies results in the background. Ideal for building CLIs, migrations, or API layers. Users provide a goal, and the system handles the entire workflow without manual intervention.

This skill enables applying John Ousterhout's design principles to reduce complexity in software systems. It guides decisions on module boundaries, API design, information hiding, and abstraction depth. Use it when refactoring shallow interfaces or managing cognitive load during development. Ideal for architects and senior engineers optimizing system structure and ensuring maintainable codebases through proper abstraction layers.

This skill enables developers to orchestrate Android development tasks via the command line. It supports project creation, SDK management, device interaction, emulator control, and UI inspection. Users can install, update, and manage the Android CLI tool, run applications, capture screenshots, and search official documentation for guidance on APIs and best practices.

A comprehensive guide and skill for building robust, production-ready REST API endpoints. This skill covers full lifecycle development, including input validation, centralized error handling, authentication/authorization checks, CRUD operations, pagination, and generating proper API documentation. It ensures that back-end services are secure, scalable, and adhere to industry best practices.

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.

Learn to create, modify, and deploy Apify Actors using CLI tools. Covers template selection, dependency management, logic implementation, schema configuration, and security best practices for serverless automation tasks.

Design and build official Apify integrations for company products with minimal external help. Covers workflow automation, AI agent plugins, framework packages, and direct clients. Includes guidance on vocabulary mirroring, asynchronous run flows, and cost controls. Use Apify MCP for research and follow category-specific reference files for UX design and capability matrices to ensure a first-class integration.

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.

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.

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.

This skill empowers you to implement secure backend coding practices, focusing on input validation, authentication, and API security. It covers vulnerability prevention, defensive programming, and secure architecture implementation. Ideal for building security-first applications that resist common attack vectors like SQL injection, XSS, and CSRF. Includes expertise in database protection, secret management, and HTTP security headers.

This skill covers backend architecture patterns, API design, and database optimization specifically for Node.js, Express, and Next.js. It provides server-side best practices for building scalable applications. Use this for designing robust backend systems and optimizing performance in modern web development environments.
