This page documents the example-skills plugin bundle: its twelve constituent skills, their categories, intended use cases, and licensing. These skills are open-source reference implementations licensed under Apache 2.0.
For the parallel bundle of document-processing skills (docx, xlsx, pptx, pdf), see Document Skills. For installation instructions, see Quick Start. For a deep dive into the skill-creator skill specifically, see Skill Creator.
All twelve skills in the example-skills bundle are licensed under Apache 2.0. This distinguishes them from the document-skills bundle, which is source-available but not open-source.
The bundle is registered in `.claude-plugin/marketplace.json24-43 as the example-skills plugin entry under the anthropic-agent-skills marketplace. It uses "strict": false, meaning unrecognized fields in SKILL.md frontmatter are tolerated rather than rejected.
Skills in this bundle are pre-installed for paid plans on Claude.ai and can be installed in Claude Code via:
/plugin install example-skills@anthropic-agent-skills

The twelve skills are grouped into four functional categories.

These five skills address visual output generation and design system enforcement.
| Skill directory | name in SKILL.md | Primary use case |
|---|---|---|
skills/algorithmic-art | algorithmic-art | Generates visual art programmatically using code-based drawing techniques |
skills/canvas-design | canvas-design | Produces canvas-based visual compositions and layouts |
skills/frontend-design | frontend-design | Creates polished UI components and front-end markup with visual design sensibility |
skills/theme-factory | theme-factory | Generates consistent design tokens, color palettes, and theming configurations |
skills/brand-guidelines | brand-guidelines | Applies and enforces organizational brand standards across outputs |
algorithmic-artLocated at skills/algorithmic-art/. Generates images and visual patterns using algorithmic and generative techniques. Intended as a demonstration of Claude producing deterministic visual outputs through code rather than image models.
canvas-designLocated at skills/canvas-design/. Produces structured visual layouts using canvas-style composition. Targets use cases where pixel-level design control is needed within a code artifact.
frontend-designLocated at skills/frontend-design/. Guides Claude in producing well-structured, visually refined front-end code (HTML/CSS/JS). Codifies design best practices for Claude to apply when generating UI components.
theme-factoryLocated at skills/theme-factory/. Generates design system tokens: color palettes, typography scales, spacing values, and theme configurations. Useful for bootstrapping or extending a consistent visual language across a project.
brand-guidelinesLocated at skills/brand-guidelines/. Encodes brand rules (tone, color usage, typography, logo treatment) as SKILL.md instructions so Claude applies them consistently when producing any branded output.

These three skills support written communication workflows.
| Skill directory | name in SKILL.md | Primary use case |
|---|---|---|
skills/internal-comms | internal-comms | Drafts internal organizational communications (announcements, memos, updates) |
skills/slack-gif-creator | slack-gif-creator | Creates animated GIFs intended for Slack reactions and messages |
skills/doc-coauthoring | doc-coauthoring | Supports collaborative document authoring with structured writing conventions |
internal-commsLocated at skills/internal-comms/. Instructs Claude to draft internal communications in a consistent organizational voice. Covers announcements, all-hands summaries, and team updates. Demonstrates how a skill can encode an organization's tone and format expectations.
slack-gif-creatorLocated at skills/slack-gif-creator/. Generates animated GIF content appropriate for Slack reactions. Demonstrates media artifact generation within a skill context.
doc-coauthoringLocated at skills/doc-coauthoring/. Supports structured collaborative writing. Provides Claude with conventions for tracking suggestions, maintaining authorial intent, and formatting long-form documents for multi-author contexts.

These two skills help developers build and extend the Claude skills ecosystem itself.
| Skill directory | name in SKILL.md | Primary use case |
|---|---|---|
skills/skill-creator | skill-creator | Builds, evaluates, and iterates on new SKILL.md skills |
skills/mcp-builder | mcp-builder | Generates Model Context Protocol (MCP) server definitions |
skill-creatorLocated at skills/skill-creator/. This is the most complex skill in the repository. It guides Claude through the full lifecycle of authoring a new skill: capturing intent, writing SKILL.md, generating evaluation test cases, running parallel benchmarked evaluations, and packaging the result. It contains a full sub-agent network (agents/grader.md, agents/comparator.md, agents/analyzer.md), benchmarking scripts, and an eval viewer. See Skill Creator for complete documentation.
mcp-builderLocated at skills/mcp-builder/. Instructs Claude to generate MCP server scaffolding from a description of tools and resources. Demonstrates how a skill can encode a complex technical output format (MCP server definitions) as repeatable instructions.

These two skills address web artifact generation and automated UI testing.
| Skill directory | name in SKILL.md | Primary use case |
|---|---|---|
skills/web-artifacts-builder | web-artifacts-builder | Constructs complete, runnable web application artifacts |
skills/webapp-testing | webapp-testing | Drives automated testing of web application UIs |
web-artifacts-builderLocated at skills/web-artifacts-builder/. Instructs Claude to produce self-contained web application artifacts — HTML, CSS, and JavaScript bundles that can be previewed directly. Targets use cases where a complete runnable deliverable is required rather than isolated code snippets.
webapp-testingLocated at skills/webapp-testing/. Guides Claude in writing and executing automated tests against web application interfaces. Demonstrates how a skill can encode a testing methodology and toolchain so Claude applies it consistently.
Sources: `README.md14 `.claude-plugin/marketplace.json41-42
The example-skills bundle serves two purposes simultaneously:
SKILL.md files demonstrate patterns for structuring skill instructions, scoping descriptions for accurate trigger matching, organizing optional scripts/ and agents/ subdirectories, and combining Claude's reasoning with external tool invocations.The Apache 2.0 license on all twelve skills means they can be forked, modified, and redistributed as the basis for custom organizational skills. The skills/skill-creator skill is specifically designed to accelerate this process — it can ingest one of these reference skills as a baseline and help iterate toward a custom variant.
For the template to start a new skill from scratch, see template/ and the developer guide at Creating a New Skill. For validation tooling, see Skill Validation.
