Skills in detail

Each entry below covers what the skill does, how to trigger it, and a concrete example of input and output.

🛠️
/skill-creator
Anthropic · ⬇ 42.9K · Slash command + auto
+ Install

Helps you create, edit, and improve other skills. Use it when you want to write a new SKILL.md from scratch, refine an existing one, run automated evals, or optimise a skill's description so Claude triggers it more accurately.

Example prompt
“Create a skill that formats all my responses as structured reports with an executive summary.”
What Claude produces
A complete SKILL.md with frontmatter, trigger description, and step-by-step formatting instructions — ready to save to ~/.claude/skills/.
🎨
/canvas-design
Anthropic · ⬇ 502K · Slash command
+ Install

Generates visual documents — infographics, slides, and print-ready layouts — as .png or .pdf artifacts. It applies design principles like alignment, contrast, and hierarchy so you get polished output without knowing design tools.

Example prompt
“Design a one-page summary of our Q1 product roadmap with icons and a timeline.”
What Claude produces
A .pdf artifact containing a structured, visually designed roadmap with labelled sections, colour blocks, and iconography.
🌐
/web-artifacts-builder
Anthropic · ⬇ 313K · Slash command + auto
+ Install

Builds fully interactive HTML artifacts inside claude.ai — landing pages, dashboards, calculators, or any multi-component web page. Uses modern CSS and JS. The result renders in the artifact preview panel immediately.

Example prompt
“Build me a landing page for a productivity app called TaskPilot with a hero, feature list, and CTA button.”
What Claude produces
A self-contained HTML artifact with responsive layout, styled sections, and a working CTA button — previewed live in the panel.
🔌
/mcp-builder
Anthropic · ⬇ 255K · Slash command
+ Install

Guides you through building a Model Context Protocol (MCP) server — the standard way to give Claude access to external tools, APIs, and data sources. Useful for developers integrating Claude into their own systems.

Example prompt
“Help me create an MCP server that lets Claude read files from my local project directory.”
What Claude produces
Step-by-step server scaffold with the correct MCP schema, tool definitions, and a working TypeScript or Python starter file.
🖼️
/theme-factory
Anthropic · ⬇ 250K · Slash command
+ Install

Applies a consistent visual theme across any artifact — colour palette, typography, spacing, and component style. Useful when you want all your slides, docs, and pages to share the same look without manually styling each one.

Example prompt
“Apply a dark, professional theme to all future artifacts — deep navy background, white text, and teal accents.”
What Claude produces
A theme definition artifact you can reference in subsequent requests. Future artifacts automatically adopt the palette and type settings.
🏷️
/brand-guidelines
Anthropic · ⬇ 227K · Slash command
+ Install

Encodes Anthropic's official brand colours, fonts, and component patterns and applies them to any artifact you generate. Ideal when producing content that needs to stay on-brand without manually specifying style rules each time.

Example prompt
“Create a product announcement post that follows Anthropic brand guidelines.”
What Claude produces
A styled announcement document using the correct brand font (Söhne), colour tokens, and layout proportions from the official guidelines.

Choosing the right skill

If you want to…Use this skill
Build or improve a skill/skill-creator
Create a visual document, infographic, or slide deck/canvas-design
Build an interactive webpage or dashboard/web-artifacts-builder
Connect Claude to an external tool or API/mcp-builder
Apply a consistent style to all your artifacts/theme-factory
Match Anthropic's official design language/brand-guidelines
💡 Tip: You can install all six skills at once and let Claude pick the right one automatically. For tasks that clearly match a specific skill, typing the slash command (e.g. /canvas-design) forces that skill even if auto-detection would choose differently.
