Automated guidance for designing DynamoDB tables within AWS, offering best-practice patterns, production-ready configurations, and validation tailored to compute, storage, networking, and serverless use cases.

This comprehensive guide offers patterns and best practices for building robust, maintainable, and fast End-to-End (E2E) test suites using Playwright. It details essential concepts like Page Object Model (POM), advanced configuration, handling flaky tests, artifact management, and seamless integration into CI/CD pipelines. Essential for QA engineers and developers building web automation frameworks.

This skill provides comprehensive guidance on building reliable, fast, and maintainable end-to-end (E2E) test suites. It ensures code quality by validating critical user journeys and catching regressions in complex workflows before deployment. Essential for setting up robust CI/CD pipelines, cross-browser compatibility, and establishing rigorous QA standards.

This skill provides expert guidance for building robust, scalable, and fault-tolerant applications using Elixir. It specializes in mastering OTP patterns, Phoenix LiveView, concurrent programming, and distributed system design. Use it for complex Elixir development tasks requiring best practices and high reliability.

Automate Emailable operations through Composio's Emailable toolkit by discovering current Rube MCP tools before executing workflows, managing connections, and reusing sessions while honoring tool schemas and pagination requirements.

Automates Emaillistverify operations via Composio’s Rube MCP by discovering current tool schemas, managing connections, and executing multi-tool flows with session and memory best practices for reliable validation.

A comprehensive guide for selecting and optimizing embedding models for advanced vector search and retrieval-augmented generation (RAG) applications. This guide covers model comparison, chunking strategies, dimension reduction techniques, and provides runnable Python templates for both OpenAI and local Sentence Transformer implementations.

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.

Analyzes smart contract codebases to enumerate externally callable state-changing functions, classify their access (public/role/contract-only), and produce structured audit-ready reports for Solidity, Vyper, Solana/Rust, Move, TON, and CosmWasm projects.

Provides comprehensive, step-by-step guides for developers to set up complete development environments from scratch. It covers installing dependencies (Node.js, Python, Docker), configuring environment variables, and using platform-specific commands for macOS, Linux, and Windows. Ideal for starting new projects, onboarding team members, or troubleshooting setup issues.

Guides DevOps users through managing environment variables with best practices, code/config generation, and validation while covering foundational version control, containerization, CI/CD, and infrastructure topics.

This skill is designed for advanced error detective work. It analyzes complex log streams, correlates stack traces across distributed systems, and detects anomalous error patterns. It helps identify root causes by correlating errors with system deployments and changes, providing actionable findings for immediate fixes and long-term prevention strategies.
