Skill UI

A comprehensive guide covering fundamental principles for creating 2D games. It details best practices for sprite organization (atlases, animation), tilemap design, physics implementation (collision shapes, fixed timestep), camera systems (follow, look-ahead), and genre-specific patterns like platformers and top-down games. Essential for game developers building robust 2D experiences.

Implement comprehensive observability for Apollo.io API integrations. This skill provides structured instrumentation covering Prometheus metrics (request count, latency, rate limits, credits used), structured logging with PII redaction, and OpenTelemetry tracing. It ensures reliable tracking of API health, performance, and resource consumption.

This skill provides a comprehensive guide and implementation for handling API rate limiting and network retries (429 errors). It utilizes advanced patterns like the Sliding Window Limiter for per-endpoint rate control, exponential backoff with jitter, and request queuing with concurrency control. Ideal for building robust, resilient applications that interact with rate-limited external APIs like Apollo.io.

A guide for building secure, scalable, and robust authentication and authorization systems. This skill covers industry-standard practices, including OAuth2, JWT, OIDC, RBAC, and session management, helping developers design secure APIs and identity infrastructure.

An expert developer specializing in secure backend coding practices, vulnerability mitigation, and robust API design. Proficient in preventing common attacks such as SQL injection, XSS, and CSRF. Covers comprehensive areas including input validation, authentication mechanisms (OAuth 2.0, MFA), database security, and implementing necessary security headers (CSP, HSTS) for building secure-by-design applications. Ideal for implementing security fixes or building new, hardened backend services.

A comprehensive, multi-phase workflow designed for creating production-ready Bash scripts. This guide covers the entire development lifecycle, including defensive pattern implementation, structured error handling (traps, retry logic), logging strategies, rigorous unit testing using Bats, and professional documentation. Ideal for system administration, CI/CD automation, and core DevOps scripting.

This comprehensive skill guide details the implementation of robust and secure API authentication systems. It covers industry standards like JWT, OAuth 2.0 (including various flows), and API key management. Key features include role-based access control (RBAC), refresh token rotation, session management, and brute-force protection, ensuring secure communication for diverse service architectures.
