What Does the eli5 Plugin Do and How to Use It in Claude Code

The eli5 plugin generates dead-simple HTML visual explainers that break down complex topics using big illustrations and minimal text, accessible via the /eli5 slash command or direct skill invocation in Claude Code.

The eli5 plugin—short for "Explain Like I'm 5"—is a lightweight skill in the anthropics/claude-plugins-community repository that transforms any user-provided topic into a self-contained HTML artifact designed for absolute beginners. Unlike standard text responses, this plugin produces visual-first explanations with large graphics and concise captions that require no prior domain knowledge to understand.

What Is the eli5 Plugin?

The eli5 plugin is a command-style Claude Code skill that converts abstract concepts into picture-heavy HTML explainers. According to the source code in anthropics/claude-plugins-community, the plugin targets audiences who need fundamental explanations without technical jargon, rendering output as browser-ready HTML files rather than markdown text.

Plugin Architecture and Source Files

The plugin resides in the eli5/ directory and follows the standard Claude Code plugin layout. Three core files define its behavior:

• eli5/.claude-plugin/plugin.json – The manifest file declaring the plugin's metadata, including name, version, description, author, license, and keywords.
• eli5/skills/eli5/SKILL.md – The skill definition file that maps user input to the generation prompt using the $ARGUMENTS placeholder.
• eli5/README.md – Human-readable documentation covering usage examples and feature overviews.

In SKILL.md, the skill definition injects user input into a structured prompt template:

Topic: $ARGUMENTS

When invoked, Claude processes this topic through its LLM to generate an HTML artifact containing large visual illustrations and plain-language captions. No external APIs or runtime dependencies are required—the entire pipeline executes within Claude's native capabilities.

How to Use the eli5 Plugin

You can trigger the eli5 plugin through two distinct invocation patterns in Claude Code.

Slash Command Syntax

The most direct method uses the /eli5 slash command followed by your topic:

/eli5 how does DNS work

Claude responds with a self-contained HTML file displaying a large graphic of a DNS resolver paired with a brief caption such as "DNS translates domain names to IP addresses."

Skill Call Method

Alternatively, reference the skill name explicitly in natural language or programmatic calls:

# Pseudocode for Claude Code integration

response = claude.call_skill(
    skill_name="eli5",
    arguments="what is a neural network"
)
html_artifact = response.artifact  # contains the generated HTML

with open("neural_network_eli5.html", "w") as f:
    f.write(html_artifact)

Opening neural_network_eli5.html renders a big-picture explanation of neural networks optimized for visual comprehension.

How the eli5 Plugin Generates Explanations

The generation process relies entirely on Claude's internal LLM capabilities defined in eli5/skills/eli5/SKILL.md. When the skill receives the $ARGUMENTS value, it constructs a prompt demanding:

1. Visual hierarchy – Large, descriptive images or diagrams that dominate the viewport.
2. Minimal text – Single-sentence captions explaining the core concept without technical terminology.
3. Self-contained output – A complete HTML file ready for immediate browser rendering.

Because the plugin operates without external service calls, latency remains minimal and no API keys are required beyond standard Claude Code access.

Summary

• The eli5 (Explain Like I'm 5) plugin converts complex topics into visual HTML explainers with big pictures and simple text.
• Source files include eli5/.claude-plugin/plugin.json (manifest), eli5/skills/eli5/SKILL.md (skill logic), and eli5/README.md (documentation).
• Invoke via /eli5 <topic> slash command or programmatic skill_name="eli5" calls.
• The plugin uses the $ARGUMENTS placeholder to inject topics into a generation prompt that produces self-contained HTML artifacts.
• No external APIs or dependencies are required—generation happens entirely within Claude's LLM.

Frequently Asked Questions

How do I install the eli5 plugin in Claude Code?

The eli5 plugin comes bundled with the anthropics/claude-plugins-community repository. Ensure your Claude Code installation includes the eli5/ directory with the plugin.json manifest and SKILL.md definition files. Once present in the plugins path, the /eli5 command becomes automatically available in your Claude Code chat interface.

What file format does the eli5 plugin output?

The plugin generates self-contained HTML files that open directly in any modern web browser. These artifacts feature large visual illustrations and minimal text explanations designed for immediate consumption without additional rendering engines or markdown parsers.

Can I use the eli5 plugin for technical programming concepts?

Yes. While the plugin simplifies explanations for beginners, it effectively handles technical topics like DNS resolution, neural networks, or blockchain mechanics. The skill specifically targets "zero prior knowledge" audiences, making it ideal for onboarding non-technical stakeholders to complex programming or infrastructure concepts.

Does the eli5 plugin require external API keys or services?

No. According to the source code in eli5/skills/eli5/SKILL.md, the plugin operates entirely within Claude's native LLM infrastructure. It does not call external image generation APIs, search services, or third-party platforms—all HTML generation occurs through Claude's internal text and markup capabilities.
