All Skills

Design critique (Nielsen heuristics) + accessibility audit (WCAG 2.2 AA)

Build and test Solidity smart contracts with Foundry toolkit. Use when developing Ethereum contracts, writing Forge tests, deploying with scripts, or debugging with Cast/Anvil. Triggers on Foundry commands (forge, cast, anvil), Solidity testing, smart contract development, or files like foundry.toml, *.t.sol, *.s.sol.

Use when building Angular 17+ applications with standalone components or signals. Invoke for enterprise apps, RxJS patterns, NgRx state management, performance optimization, advanced routing.

Run the GRACE architectural planning phase. Use when you have requirements and technology decisions defined and need to design the module architecture, create contracts, and build the knowledge graph. Produces development-plan.xml and knowledge-graph.xml.

This skill aims to spot rounding issues or exploits inside Solidity smart contracts. This skill should be used when dealing with DeFi smart contracts that include math operations for assets to shares minting or the other way around, interest calculations, fee calculations or math operations related to swapping/ trading activity.

Pragmatic coding standards - concise, direct, no over-engineering, no unnecessary comments

Production deployment principles and decision-making. Safe deployment workflows, rollback strategies, and verification. Teaches thinking, not scripts.

Quick code review for small PRs (<100 lines). Focuses on basic code quality, naming conventions, and obvious bugs.

Comprehensive PDF manipulation toolkit for extracting text and tables, creating new PDFs, merging/splitting documents, and handling forms. When Claude needs to fill in a PDF form or programmatically process, generate, or analyze PDF documents at scale.

Documentation templates and structure guidelines. README, API docs, code comments, and AI-friendly documentation.

Game development orchestrator. Routes to platform-specific skills based on project needs.

This skill should be used when investigating code, understanding implementations, finding patterns, locating files, or gathering context about how a codebase works. Applies to tasks like "find where X is implemented", "how does Y work", "find examples of Z", or general codebase exploration.

Standards for authoring SDD plugin commands — frontmatter, user interaction, skill/agent invocation, CLI integration, and output formatting.

Design thinking and decision-making for web UI. Use when designing components, layouts, color schemes, typography, or creating aesthetic interfaces. Teaches principles, not fixed values.

Game audio principles. Sound design, music integration, adaptive audio systems.

Understanding Reinforcement Learning from Human Feedback (RLHF) for aligning language models. Use when learning about preference data, reward modeling, policy optimization, or direct alignment algorithms like DPO.

3D game development principles. Rendering, shaders, physics, cameras.

Internationalization and localization patterns. Detecting hardcoded strings, managing translations, locale files, RTL support.

Web browser game development principles. Framework selection, WebGPU, optimization, PWA.

PC and console game development principles. Engine selection, platform features, optimization strategies.

This skill should be used when the user asks to "bootstrap few-shot examples", "generate demonstrations", "use BootstrapFewShot", "optimize with limited data", "create training demos automatically", mentions "teacher model for few-shot", "10-50 training examples", or wants automatic demonstration generation for a DSPy program without extensive compute.

Design system creation (Apple HIG) + Figma auto-layout specifications

Core Go style principles and formatting guidelines from Google and Uber style guides. Use when writing any Go code to ensure clarity, simplicity, and consistency. This is the foundational skill - other Go style skills build on these principles.

VR/AR development principles. Comfort, interaction, performance requirements.
