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.

A comprehensive guide for implementing user interfaces that mimic spatial computing devices (like Apple Vision Pro). It focuses on creating digital elements with a sense of depth (Z-Space), utilizing glass-like materials via backdrop blur, and designing gaze-aware interactions, making digital information feel physically anchored in the real environment.

A comprehensive guide for implementing spatial, mixed-reality user interfaces. Inspired by Apple Vision Pro and AR aesthetics, this pattern uses environmental transparency, blurred glass-like panels, and dynamic lighting effects to create deeply integrated, context-aware layouts for web and mobile applications.

A comprehensive master guide for developers looking to embed interactive 3D scenes created in Spline.design into modern web projects. It provides specific integration methods for various frameworks, including React, Next.js, Vue, and vanilla JavaScript, ensuring optimal performance and runtime control for stunning UI/UX experiences.

Squirrel is an advanced, full-cycle AI coding skill designed to guide software development from concept to production. It automatically detects the current project state (greenfield, in-progress, or mature) and adapts an 8-phase engineering pipeline. This comprehensive workflow covers planning, building, rigorous testing, bug hunting, code polishing, documentation, and deployment readiness, ensuring high-quality, maintainable results.

This skill generates comprehensive market opportunity analysis for startups, calculating TAM, SAM, and SOM using bottom-up and top-down methodologies. It guides users through defining target markets, gathering data, validating assumptions, and creating detailed reports with actionable insights for investment thesis and growth strategy.

This guide provides a comprehensive framework for early-stage companies to track, calculate, and optimize their key performance indicators (KPIs). It covers best practices for various startup business models, guiding teams from the initial seed stage through to Series A funding. Use this skill when developing, analyzing, or refining a structured startup metrics strategy.

Guides how to craft detailed prompts for Google Stitch so it generates high-quality web and mobile UI designs, covering specificity, visual style, multi-screen structure, platform targeting, and iterative refinement.

This skill provides comprehensive guidelines for optimizing Postgres database performance and security. It covers query optimization, schema design, connection management, Row-Level Security, and concurrency handling. Use it when writing SQL, reviewing database configurations, or implementing indexes. Based on Supabase best practices to ensure efficient and secure database operations for production environments.

This skill provides comprehensive guidelines for writing idiomatic and efficient Swift code. It covers best practices for optionals, collections, value types, error handling, concurrency, and protocol-oriented design to improve code quality and maintainability.

A comprehensive guide for building or reviewing SwiftUI User Interfaces that utilize the modern Liquid Glass aesthetic. This skill focuses on correctly implementing native Apple APIs (like `glassEffect` and `GlassEffectContainer`) while ensuring proper fallback mechanisms, modifier ordering, and performance for iOS 26+ devices. Ideal for adopting cutting-edge iOS design patterns.

This skill provides a comprehensive, structured workflow for diagnosing performance bottlenecks in SwiftUI applications. It guides users through a code-first review to detect common issues like invalidation storms, layout thrash, or heavy main-thread work. When code review is insufficient, it provides detailed guidance on collecting runtime evidence using Instruments, enabling precise root cause analysis and targeted remediation strategies.
