Anthropic's official Agent Skills, all in one shelf.
The official anthropics/skills collection - document tooling (docx, pdf, pptx, xlsx), design (canvas, theme factory, brand), MCP builder, skill creator, web artifacts, and more.
Arranged in the author's recommended order. Walk through them in sequence, or open any one on its own.
Official Anthropic skill. Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one, so the result does not read as a templated default.
Create generative, algorithmic art with p5.js – flow fields, particle systems, and seeded randomness with interactive parameter exploration.
Apply Anthropic's official brand colors and typography to any artifact that benefits from the company look-and-feel.
Create beautiful visual art in .png and .pdf documents using design philosophy – posters, art, and static pieces.
Reference for the Claude API / Anthropic SDK – model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, and model migration.
Build high-quality MCP servers that let LLMs interact with external services through well-designed tools (Python FastMCP or Node/TypeScript SDK).
Create, modify, and measure Agent Skills – scaffold a skill from scratch, optimize its triggering description, and benchmark performance.
Create animated GIFs optimized for Slack – constraints, validation tools, and animation concepts for "make me a GIF of X" requests.
Style artifacts (slides, docs, HTML pages) with a theme – 10 preset color/font themes or generate a new one on the fly.
Build elaborate, multi-component claude.ai HTML artifacts with React, Tailwind, and shadcn/ui – state, routing, and rich UI.
Test local web apps with Playwright – verify frontend behavior, debug UI, capture screenshots, and read browser logs.
