Generates design system tokens including color palettes, typography scales, spacing grids, and responsive breakpoints from a base brand color. Exports to JSON, CSS, or SCSS formats. Helps maintain visual consistency across projects with automated token generation.
algorithmic-art
This skill creates algorithmic art by first generating a conceptual philosophy document, then implementing it as an interactive p5.js sketch. It produces self-contained HTML files with seeded randomness, parameter controls, and Anthropic-branded UI. The two-step process separates creative direction from technical implementation.
agent-native-architecture
This skill provides a methodology for building applications where AI agents are central, using atomic tools and system prompts instead of hardcoded logic. It teaches how to refactor existing tools by moving business decisions from code to prompts, enabling agents to achieve outcomes through loops of primitive operations.
senior-fullstack
Comprehensive fullstack development skill for building complete web applications with React, Next.js, Node.js, GraphQL, and PostgreSQL. Includes project scaffolding, code quality analysis, architecture patterns, and complete tech stack guidance. Use when building new projects, analyzing code quality, implementing design patterns, or setting up development workflows.
skill-creator
Guide for creating effective skills that extend agent capabilities with specialized knowledge, workflows, or tool integrations. Use this skill when the user asks to: (1) create a new skill, (2) make a skill, (3) build a skill, (4) set up a skill, (5) initialize a skill, (6) scaffold a skill, (7) update or modify an existing skill, (8) validate a skill, (9) learn about skill structure, (10) understand how skills work, or (11) get guidance on skill design patterns. Trigger on phrases like "create a skill", "new skill", "make a skill", "skill for X", "how do I create a skill", or "help me build a skill".
specification-validation
A tool that validates software specifications and implementations against a '3 Cs' framework (Completeness, Consistency, Correctness). It checks spec documents, compares code to design, scans files for ambiguity, and validates developer understanding. It integrates with other MCP skills and can check for constitutional rule compliance.
solution-design
This skill automates solution generation for defined problems by executing a Python script that provides multiple reasoning perspectives. It's designed for users who already have identified root causes and need structured solution options without preliminary exploration.
canvas-design
This skill guides Claude through a two-step process to create visual art. First, it generates a detailed design philosophy manifesto. Then, it uses that philosophy to produce a polished PDF or PNG artwork, emphasizing craftsmanship, minimal text, and spatial expression over literal representation.
ui-template-library
Captures visual design patterns from HTML mockups as structured prose descriptions, then applies those aesthetic 'vibes' to generate new mockups for different plugins with adaptive layouts. Manages a library of aesthetic templates with CRUD operations.
concept-scaffolding
A Claude Skill that helps design progressive learning sequences by breaking complex concepts into manageable steps. It uses Bloom's taxonomy and CEFR levels to manage cognitive load, includes validation checkpoints, and integrates AI collaboration at appropriate stages. The skill provides a structured framework for instructional designers and educators.
Playwright Browser Automation
Complete browser automation with Playwright. Auto-detects dev servers, writes clean test scripts to /tmp. Test pages, fill forms, take screenshots, check responsive design, validate UX, test login flows, check links, automate any browser task. Use when user wants to test websites, automate browser interactions, validate web functionality, or perform any browser-based testing.
aesthetic-dreaming
A structured workflow skill for capturing visual design systems through iterative questioning, enabling creation of aesthetic templates before plugin implementation with clear phase-based execution.
gcloud-usage
This skill provides practical guidance for GCP observability tasks including structured logging formats, Logging query syntax, alert policy design, and cost optimization strategies. It helps users filter logs by severity, resource type, and time ranges, and explains when to use metrics vs logs vs traces for debugging.
image-upscaling
Upscale and enhance images with Real-ESRGAN, Thera, Topaz, FLUX Upscaler via inference.sh CLI. Models: Real-ESRGAN, Thera (any size), FLUX Dev Upscaler, Topaz Image Upscaler. Use for: enhance low-res images, upscale AI art, restore old photos, increase resolution. Triggers: upscale image, image upscaler, enhance image, increase resolution, real esrgan, ai upscale, super resolution, image enhancement, upscaling, enlarge image, higher resolution, 4k upscale, hd upscale
exercise-designer
Generates Python practice exercises using evidence-based learning strategies like retrieval practice and spaced repetition. Follows an 'evals-first' design process, mapping exercises to learning objectives and success criteria. Provides structured templates for exercises and rubrics, supporting varied exercise types from fill-in-the-blank to AI-collaborative tasks.
brand-guidelines
This skill applies Anthropic's official brand colors and typography to documents and presentations. It automatically formats headings with Poppins font and body text with Lora, using specific brand colors for text and accent shapes. The tool works with python-pptx and provides fallback fonts when custom fonts aren't available.
ui
This skill generates UI components and feedback forms using shadcn/ui and Tailwind CSS. It enforces strict accessibility guidelines and design constraints, prioritizing production-ready code. It includes a quality gate for a11y checks and references detailed constraint files for implementation.
ui-styling
This skill provides detailed guidance for building React UIs using shadcn/ui components and Tailwind CSS. It includes setup instructions, component usage patterns, theming, accessibility, and responsive design. It offers practical code examples and references for common UI tasks like forms, layouts, and dark mode.
powerbi-modeling
Power BI semantic modeling assistant for building optimized data models. Use when working with Power BI semantic models, creating measures, designing star schemas, configuring relationships, implementing RLS, or optimizing model performance. Triggers on queries about DAX calculations, table relationships, dimension/fact table design, naming conventions, model documentation, cardinality, cross-filter direction, calculation groups, and data model best practices. Always connects to the active model first using power-bi-modeling MCP tools to understand the data structure before providing guidance.
frontend-design
This skill generates frontend code with strong aesthetic direction, avoiding generic AI designs. It enforces specific animation libraries (anime.js v4), provides detailed typography and color guidelines, and pushes for bold creative choices in web interfaces.
frontend-aesthetics
Provides specific guidance for avoiding generic AI-generated frontend aesthetics. Offers concrete font alternatives, color palette principles, and animation strategies. Outputs structured JSON with typography, color, animation, and background recommendations. Includes anti-pattern checklist and practical implementation examples.
