Skill UI

Implement and verify Stripe checkout, subscriptions, webhooks, and refunds with explicit server-side authorization. Covers payment flows, webhook handling, subscription management, and customer management. Provides code patterns for hosted checkout, payment intents, and setup intents. Emphasizes security boundaries and proper use of test accounts.

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 specializes in scaffolding production-ready Rust applications. It generates complete project structures using Cargo tooling, ensuring proper module organization, testing setup, and configuration following Rust best practices. It supports binary, library, workspace, and web API project types with idiomatic code patterns.

This skill provides pre-configured project scaffolding templates for initiating new applications from scratch. It covers 12 diverse technology stacks including Next.js, Express, Python FastAPI, React Native, Flutter, and more. Users can select the appropriate template based on their project type, such as full-stack web apps, APIs, mobile applications, or desktop software. It streamlines the setup process by offering ready-made structures and configurations tailored to specific development needs.

This skill maps identified security threats to appropriate controls and mitigation strategies. It is essential for prioritizing security investments, building comprehensive remediation roadmaps, validating existing control coverage, and performing detailed risk treatment planning. It helps organizations design robust, defense-in-depth security architectures.

This skill involves conducting threat modeling using the STRIDE methodology to identify potential security threats, assess risks, and design appropriate security controls. It is essential when designing secure systems, making architectural changes, or preparing for security audits. The process includes analyzing data flows, identifying trust boundaries, and mitigating risks related to spoofing, tampering, repudiation, information disclosure, denial of service, and privilege escalation.

Construct a structured rendering pipeline for advanced Three.js scenes, managing shared buffers and signal ordering. Supports depth, normals, albedo, bloom, tone mapping, and grading. Ideal for composing multiple image-space systems rather than single effects. Ensures proper exposure metering and output conversion.

This skill enables building view-aligned and screen-space surface effects in Three.js, including touch-history frost, ping-pong accumulation, and procedural rain droplets. It covers reduced-resolution blur, crystalline masks, and two-scale refraction through wet glass. Use persistent or procedural history explicitly without faking accumulation with noise.

Train or fine-tune SentenceTransformer, CrossEncoder, and SparseEncoder models for retrieval, similarity, clustering, classification, reranking, and embedding tasks. This skill provides production-ready templates with proper loss functions, evaluators, and training configurations for various NLP tasks including bi-encoder, reranker, and sparse vector models.

This skill performs a quick automated lint scan to detect common design system violations in seconds. It checks for hardcoded colors, raw pixel values, old width/height syntax, physical properties, forbidden colors, missing data-slots, and improper className usage. Ideal for running after every file change to maintain design consistency and prevent technical debt in UI development projects using design tokens.

Apply StyleSeed motions to React components using five personality seeds (Spring/Silk/Snap/Float/Pulse) or distinctive keyword moves from the motion library. Translate user vibe descriptions into precise motion parameters, recommend appropriate motions for use cases, and implement them as motion.X JSX.

Provides opinionated, evolving constraints to guide agents when building interfaces. Helps identify high-impact design problems and propose implementation-ready improvements.
