Skill UI

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.

A structured workflow designed to prevent 'reinventing the wheel.' Before writing custom code, this skill guides the user through analyzing needs, conducting parallel searches across multiple channels (npm, PyPI, GitHub, MCP), evaluating candidate solutions based on maintainability and community support, and making a decision (Adopt, Extend, or Custom Build). It ensures that solutions leverage existing, proven libraries and patterns.

This skill specializes in transforming theoretical threat models, risk assessments, and business context into concrete, actionable security requirements. It is essential for writing detailed security user stories, defining robust acceptance criteria, building comprehensive security test cases, and ensuring compliance requirement mapping. Use it when bridging the gap between identifying a vulnerability and specifying how the system must be secured.

This skill generates comprehensive, high-quality, and SEO-optimized articles tailored for search engines and human readers. It ensures content incorporates best practices like E-E-A-T, natural keyword integration, clear structure (Intro, Body, Conclusion), and actionable takeaways. Use it when you need to create valuable, ranking-ready content based on specific keywords and topic briefs.

A comprehensive guide for writing efficient GLSL shaders (Vertex/Fragment) used in WebGL and game engines. Learn fundamental concepts like shader structure, uniforms, varying variables, and advanced techniques such as raymarching and post-processing effects, optimizing graphics rendering performance on the GPU.

This skill guides the mastery of smart contract security best practices for Solidity. It is essential for writing robust, secure, and efficient contracts, auditing existing code for common vulnerabilities (such as reentrancy, overflow, and access control issues), and implementing secure DeFi protocols. It focuses on preventing common attack vectors while optimizing gas usage.

This skill provides detailed guidance on authoring effective `specs.md` files for autonomous development workflows. It teaches users how to clearly define sprint goals, establish explicit scope boundaries (In/Out of Scope), and configure rigorous testing requirements (QA, UI Testing). This ensures that agentic development remains focused and prevents scope creep.

Provides a structured workflow for defining agent-agnostic subagents with isolated context, covering purpose definition, metadata configuration, prompt writing, and common specialist patterns for verification, debugging, security auditing, and review.

This skill provides comprehensive performance optimization and best practices for PostgreSQL, maintained by Supabase. It guides users on optimizing database performance, covering critical areas such as writing efficient SQL queries, designing robust schemas, implementing proper indexing, managing connection pooling, and enforcing Row-Level Security (RLS).

An expert skill designed for writing, reviewing, and refactoring SwiftUI code for iOS and macOS. It provides deep insights into modern state management (@Observable), optimizing view composition, handling data flow, and improving performance. The skill also assists with interpreting Instruments traces and adhering to Apple's latest Human Interface Guidelines.

Enforces an 80%+ coverage TDD workflow for feature builds, bug fixes, refactors, and API/component work by writing unit, integration, and Playwright E2E tests first, then implementing code, verifying coverage, and mocking downstream services.

A specialized skill designed to ensure robust software quality by covering the entire testing lifecycle. This includes defining test strategies, writing unit, integration, and E2E tests, and implementing advanced testing types like performance (k6), security (OWASP), and functional testing. It guides users through coverage analysis, debugging flaky tests, and generating detailed defect and quality reports.
