This module provides comprehensive connection methods for Azure Database for PostgreSQL Flexible Server using Node.js and TypeScript with the pg package. It supports both traditional password authentication and modern, recommended Microsoft Entra ID (passwordless) authentication. The guide demonstrates best practices, including connection pooling, parameterized queries to prevent SQL injection, and robust transaction management (BEGIN/COMMIT/ROLLBACK).

Orchestrates Cardly operations through Rube MCP and Composio, guiding users to search current tool schemas, connect the Cardly toolkit, and execute workflows via schema-compliant RUBE_MULTI_EXECUTE_TOOL calls with managed sessions and memory.

A comprehensive guide for designing cross-device applications across the Apple ecosystem. This skill helps developers adhere to the specific Human Interface Guidelines (HIG) for various platforms—including iOS, macOS, watchOS, tvOS, and visionOS. It emphasizes adapting design principles (e.g., touch-first vs. pointer-based vs. spatial) while maintaining brand consistency, ensuring a native and optimal user experience regardless of the operating system.

Implements standardized function/tool calling across various large language models (LLMs) via OpenRouter. This unified approach allows developers to build sophisticated, multi-step agents and complex workflows, regardless of the underlying provider (e.g., GPT-4o, Claude 3.5). It simplifies the process of achieving structured output and tool-augmented reasoning in production systems.

A comprehensive guide for deploying PostHog analytics platform across diverse production environments. Covers advanced configurations for Next.js/Vercel (including reverse proxy for ad blocker bypass and edge functions for server-side capture), self-hosted setups using Docker, and deployment patterns for Google Cloud Run. Ensures robust, reliable user behavior tracking regardless of the hosting platform.

This guide provides robust, production-ready strategies for integrating with the PostHog API. It teaches developers how to handle API rate limits (429 errors) gracefully using exponential backoff and retry logic. Furthermore, it covers implementing request queuing for burst protection, optimizing with data caching, and monitoring rate limit headers, ensuring stable and reliable data ingestion regardless of traffic volume.

This skill validates web applications across diverse browsers (Chromium, Gecko, WebKit) and real mobile devices. It supports both local testing using Playwright and scalable cloud testing via major platforms like BrowserStack, Sauce Labs, and Kobiton. Use it when ensuring consistent UI/UX, correct CSS rendering, and functional JavaScript behavior regardless of the target environment or device type.

This tool generates comprehensive briefing documents for scheduled meetings. It integrates data from calendar systems, email history (up to 90 days and historical), professional networking sites (LinkedIn), and past interaction records (Granola). It provides context on attendees, relationship history, key discussion points, and critical action items to ensure users are fully prepared for every call, regardless of whether it's a first introduction or a follow-up.

This guide details the implementation of advanced, phishing-resistant, passwordless authentication using Microsoft Entra ID. It covers configuring FIDO2 security keys, Windows Hello for Business, and passkey support via Microsoft Authenticator. Use this skill to eliminate reliance on passwords, mitigate credential stuffing attacks, and satisfy strict regulatory mandates for modern identity access management.

Implement robust, phishing-resistant authentication using FIDO2/WebAuthn standards. This guide covers integrating WebAuthn APIs, configuring FIDO2 servers, managing passkey enrollment, and migrating systems away from traditional passwords. Essential for meeting high-assurance security standards like NIST SP 800-63B AAL3.

A comprehensive guide and workflow for recovering deleted files (documents, images, videos, etc.) from damaged storage media, forensic disk images, or corrupted file systems. It utilizes PhotoRec's file signature-based carving engine, allowing data recovery regardless of file system damage. The process includes advanced steps for file validation, hashing, and organizing evidence for forensic analysis.

A comprehensive guide for building a FIDO2/WebAuthn relying party server using python-fido2. This skill covers the entire lifecycle of passwordless authentication, including secure credential registration (enrollment of hardware keys like YubiKey and resident passkeys) and robust authentication ceremonies. It is essential for migrating traditional password-based systems to phishing-resistant Multi-Factor Authentication (MFA).
