Skill UI

This skill provides comprehensive guidance for building scalable, maintainable, and production-ready backend applications using Node.js. It covers modern architectural patterns, best practices, and implementation details for REST APIs, GraphQL servers, microservices, authentication, real-time WebSockets, and complex database integrations (SQL/NoSQL).

Guides developers through OAuth2 Flow Helper tasks within Security Fundamentals by providing best-practice instructions, generating production-ready code/configs, and validating outputs for authentication, validation, and secure coding.

Automates OpenAPI specification work by guiding API developers through best practices, generating production-ready code/configs, and validating outputs for REST, GraphQL, and authentication design patterns.

This guide provides comprehensive error handling and debugging steps for the OpenEvidence API. It covers common failure points—including authentication issues (401, 403), query validation errors (422), rate limiting (429), and service timeouts (408). Users can learn how to diagnose the root cause of connection failures and refine their clinical queries to maximize data retrieval accuracy.

This SDK provides comprehensive, production-ready patterns for interacting with the OpenEvidence clinical evidence API. It enables developers to efficiently query medical literature, retrieve clinical guidelines, and generate evidence-based recommendations. Key features include a singleton client for consistent authentication, robust error wrappers (handling retries, invalid keys), and structured data models designed to ensure audit compliance and detailed citation provenance in complex healthcare applications.

This comprehensive guide helps users diagnose and fix common OpenRouter API errors, including authentication failures (401), rate limiting (429), and bad requests (400). It provides a complete reference table, detailed root causes, and executable code examples in Bash and Python to ensure stable API integration and robust error handling.

This guide provides a comprehensive walkthrough for setting up and authenticating with the OpenRouter API. It covers generating secure API keys, configuring environment variables, and initializing clients in Python and TypeScript. Learn best practices for secure integration, including key management, verification, and key rotation, ensuring reliable connectivity to various large language models (LLMs).

Guides API development teams through pagination helper tasks by providing best-practice guidance, ready-to-run code, and validation for REST, GraphQL, OpenAPI, and related authentication/design workflows.

Guides users through password hash generator tasks within the Security Fundamentals stack, outlining best practices, secure coding patterns, and validation checks tailored for authentication workflows.

Enables Claude to run a security-focused code review via the security-agent plugin, flagging SQL injection, XSS, authentication flaws, and unsafe dependencies with severity, location, impact, and remediation guidance for requested audits.

Automates vulnerability scans for applications and APIs via the security-test-scanner plugin, covering OWASP Top 10, SQL injection, XSS, CSRF, authentication, and authorization weaknesses while generating detailed remediation reports.

This guide provides comprehensive instructions for installing and configuring the Perplexity Sonar API authentication. It details setting up the necessary environment variables and using the standard OpenAI client library (for both Node.js and Python) to connect to Perplexity's API endpoint. Learning this process is essential for developers starting a new Perplexity integration, setting up API keys, or verifying API connectivity.
