Skill UI

Provides a comprehensive guide and framework for executing end-to-end (E2E) tests. It simulates real user interactions across the entire application stack, covering browser UI, API calls, and database operations. The guide details best practices like implementing the Page Object Model (POM), configuring multi-browser environments (Playwright, Cypress, Selenium), and establishing robust error handling mechanisms to ensure high application stability and quality.

Introduces deliberate code mutations, reruns the suite, and reports surviving mutants plus a mutation score whenever the user asks to assess or improve test effectiveness.

Runs a predefined suite of smoke tests to verify key application functionality, authentication, integrations, and system health after deployments, upgrades, or configuration updates.

This skill provides comprehensive, production-grade patterns for asynchronous programming in Rust using the Tokio runtime. It covers essential concepts like tasks, channels, and streams, along with robust error handling techniques. Use it when developing concurrent network services, building complex async applications, or optimizing performance in Rust.

Expert skill for writing, reviewing, and debugging idiomatic Rust code, focusing on memory safety and zero-cost abstractions. Specializes in advanced concepts like ownership patterns, explicit lifetime management, trait-based API design, and building concurrent async applications using Tokio. Use this when developing high-performance, reliable, systems-level software in Rust.

Expert skill for building high-performance, memory-safe systems, web services, and complex libraries using modern Rust (1.75+). Specializes in advanced async programming with Tokio, zero-cost abstractions, and mastering ownership and lifetime rules. Ideal for implementing scalable backend APIs, low-level networking, and performance-critical components where memory safety is paramount.

Summarizes Rust systems programming best practices, covering ownership, traits, async patterns, error handling, builders, and safety reminders for building robust server components.

Automates S3 bucket policy generation within AWS, offering step-by-step guidance, safeguards best practices, and produces production-ready configurations for compute, storage, networking, and serverless scenarios.

Automates guidance on setting up and verifying AWS S3 lifecycle configurations, delivering best-practice steps, reusable templates, and validation for storage automation tasks.

Guide for automating Safetyculture tasks through Composio’s Rube MCP toolkit, covering discovery, connection checks, schema compliance, and multi-tool execution workflows for reliable inspections.

This skill provides patterns and implementation templates for managing complex, long-running business processes across multiple independent services. It focuses on implementing the Saga pattern, ensuring data consistency in microservices architectures. It defines clear states, handles step execution, and crucially includes compensation logic to reliably roll back changes when any part of the workflow fails.

Orchestrates Sage ERP tasks through Composio’s Sage toolkit via Rube MCP, enforcing tool discovery, connection checks, schema compliance, and structured multi-step execution with remembered sessions.
