Skill UI

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

Ruzzy is a coverage-guided Ruby fuzzer leveraging libFuzzer to exercise both pure Ruby code and native C extensions; follow the provided installer, harness patterns, and sanitizer-aware runs to validate Ruby apps or gems for memory safety issues.

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.

A specialized methodology for reviewing APIs, configuration schemas, and interfaces to identify 'footguns'—design choices where the path of least resistance leads to insecurity. This analysis focuses on making secure usage the default, covering topics like dangerous defaults, primitive vs. semantic type safety, and insecure algorithm selection. It is crucial for architects and reviewers to prevent developer misuse at the design level.

This expert guides you through building modern, high-performance applications across Apple platforms (iOS, macOS, watchOS, tvOS) using Swift 5.9+. It specializes in SwiftUI state management, Protocol-Oriented Architecture, concurrent programming with async/await and Actors, and implementing best practices for type safety and performance optimization. Ideal for developing complex, robust applications.

This skill guides developers through advanced, safe, and systematic code refactoring using Test-Driven Development (TDD) principles. It provides a comprehensive workflow encompassing pre-assessment, detecting code smells, applying major design patterns (SOLID, Factory, Strategy), optimizing performance, and ensuring safety through rigorous, incremental testing. Use this when improving code structure, restructuring large components, or updating legacy systems while guaranteeing functional integrity and maintainability.

A specialized skill for building modern Vue 3 applications using pure JavaScript, completely avoiding TypeScript. It implements the Composition API, configures modern build tools like Vite, and ensures robust type safety by utilizing JSDoc annotations (@param, @returns, @typedef) instead of a compiler. Ideal for teams preferring vanilla JavaScript, migrating from Vue 2, or needing quick prototypes without a TS setup.

This policy set establishes comprehensive guardrails for using AI coding assistants (like Windsurf/Cascade). It governs terminal commands, enforces workspace isolation (preventing access to secrets/credentials), and integrates CI/CD gates for code quality. Use this when setting up team development standards, mandatory code review policies for AI output, or implementing secure development pipelines.

Guides writing Hookify rules that watch commands, files, prompts, or stop events, using YAML frontmatter to define patterns, actions, and messages for enforcing safety checks or reminders.

Automate Zylvie operations via Composio’s Zylvie toolkit through the Rube MCP workflow, covering MCP setup, connection checks, tool discovery, execution patterns, and safety steps for schema compliance and pagination.

Creates security-focused skills for automation or training environments, enabling teams to define and deploy safety-oriented routines quickly.

A comprehensive, multi-phase security audit tool designed to evaluate AI agent skills before deployment. It detects critical vulnerabilities, including prompt injection, malicious code, excessive permissions, secret exposure, and supply chain risks, ensuring the integrity and safety of your agent environment.
