Skill UI

This skill guides the development of production-grade APIs, MCP servers, and enterprise backends using modern C#/.NET best practices. It covers essential architectural components such as dependency injection (DI), advanced caching strategies (e.g., Redis), data access optimization with EF Core/Dapper, and implementing resilience patterns, ensuring robust and scalable software design.

This skill specializes in building robust, scalable, and cloud-native backend microservices using the latest .NET 8 and C# 12 features. It masters modern architectural patterns, including Clean Architecture, CQRS with MediatR, and minimal APIs. Expertise covers secure authentication (JWT), data persistence with Entity Framework Core, asynchronous programming best practices, and comprehensive unit/integration testing, ensuring highly maintainable and performant code.

Automates Microsoft Dynamics 365 CRM workflows via the Dynamics CRM Web API, letting you create and update leads, accounts, contacts, opportunities, orders, invoices, and support cases from a connected Rube MCP server.

A comprehensive guide for building robust, event-driven APIs using Webhooks, Server-Sent Events (SSE), and message brokers (e.g., Kafka, RabbitMQ). This skill covers advanced patterns like the transactional outbox pattern, implementing event schemas, managing webhooks with retry logic, and establishing real-time streaming endpoints for asynchronous microservices communication. Ideal for architecting complex, scalable, and resilient systems.

Guides using Composio's Eodhd Apis toolkit through the Rube MCP to search tool schemas, manage connections, and run multi-tool workflows with schema-compliant inputs and memory/session handling.

Automates API Integration error mapping by guiding best practices, generating production-ready code, and validating configurations whenever an error mapping helper workflow is requested.

Auto-activating skill that assists with API Etag handler tasks, guiding REST/GraphQL/OpenAPI/authentication patterns, generating production-ready code, and validating standards.

Provides step-by-step guidance for automating Etermin operations through Composio's Rube MCP, covering tool discovery, connection checks, execution patterns, and schema compliance requirements when using RUBE_* APIs.

A comprehensive guide to diagnosing and resolving common errors encountered when using the Evernote API. It covers three main exception types—User, System, and Not Found—and provides practical solutions, including ENML validation, rate limit retry mechanisms, and safe resource retrieval patterns, ensuring robust application integration.

A comprehensive toolkit designed to debug and troubleshoot Evernote API integrations. It provides deep logging of requests, responses, and timings. Features include an instrumented client wrapper for zero-config tracing, ENML content validation with auto-fix capabilities, and token inspection utilities to diagnose connectivity issues and quota limits.

A comprehensive guide providing a minimal working example for integrating with the Evernote Cloud API. It covers basic note creation, demonstrates the required ENML (Evernote Markup Language) format, and teaches core operations like listing notebooks and retrieving note details. Ideal for developers starting a new integration or testing API setup.

This runbook provides comprehensive, step-by-step procedures for managing critical incidents involving Evernote integrations. It covers diagnosing API outages, resolving persistent rate limits, handling authentication failures, and recovering from data synchronization issues. Use this guide during production troubleshooting or service outages to ensure rapid and systematic incident response, including circuit breaker activation and graceful degradation strategies.
