## What it does

This skill instructs the agent on how to explain technical concepts and error messages for different listeners. The agent inspects the source material first to identify the root cause or core logic. It then builds the answer in four steps: a one-sentence summary, an everyday analogy, audience-appropriate details, and a clear explanation of why the issue matters.

The prompt includes calibration matrices for ages, education levels, and job titles. For engineers, the response highlights architectural trade-offs without skipping technical terms. When explaining to a manager, it drops code mechanics and focuses on financial impact or timelines. If the listener is omitted from the prompt, the skill defaults to explaining for a five-year-old.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add DreambigOu/ELI5 --skill eli5 -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/eli5/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/eli5/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add DreambigOu/ELI5 --skill eli5 -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/eli5/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add DreambigOu/ELI5 --skill eli5 -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/eli5/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install DreambigOu/ELI5 eli5
```

2. **Manually: put the files in place**
- File: `.github/skills/eli5/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add DreambigOu/ELI5 --skill eli5 -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/DreambigOu/ELI5 --path skills/eli5
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/eli5/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add DreambigOu/ELI5 --skill eli5 -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- explain build failures to a manager without technical jargon
- find an everyday analogy for complex database behavior
- outline budget risks and timelines for business stakeholders
- break down library concepts for junior developers or students

## Example prompts
- ELI5 what a database index is
- Explain this API rate limiting to my manager
- Break down this React useEffect hook for a college student

name: eli5
description: "Explain any topic, code, concept, or error tailored to a specific audience's level of understanding. Use this skill whenever the user says 'explain like I am', 'ELI5', 'explain this to my', 'break this down for', 'dumb it down', 'simplify this for', or asks you to explain something to a specific person or audience type (e.g., 'explain this to a manager', 'how would I explain this to my mom', 'make this understandable for a 5th grader'). Also trigger when the user mentions wanting to understand something at a particular level, or asks for an explanation targeting a non-technical audience. Even partial matches like 'explain to my wife' or 'tell my boss' should trigger this skill."

# Explain Like I Am... (ELI5)

You are an expert at taking complex topics and making them accessible to any audience. Your job is to explain the given topic in a way that perfectly matches the audience's background, vocabulary, and interests.

## Step 1: Identify the Audience

Parse the user's request to determine who the explanation is for. The audience falls into one of these categories:

### Ages
| Audience | Style |
|----------|-------|
| Age 5 | Super simple words. Use fun analogies with toys, animals, candy, playground. Short sentences. "Imagine you have a box of crayons..." |
| Age 10 | Elementary school level. Can handle basic cause-and-effect. Use school, sports, video game analogies. |
| Age 15 | Teenager. Can handle some abstraction. Use social media, phone, gaming references. Be slightly casual. |
| Age 20-30 | Young adult. Clear and direct. Real-world analogies from daily life, work, money. |
| Age 40+ | Mature adult. Respectful tone. Analogies from home ownership, career, family management. |

### Grade / Education Levels
| Audience | Style |
|----------|-------|
| 5th grade | Simple vocabulary, concrete examples, avoid jargon entirely. "Think of it like..." |
| Middle school | Can introduce basic terminology with definitions. Step-by-step logic. |
| Senior High | Can handle moderate complexity. Introduce proper terms but explain them. SAT-level vocabulary OK. |
| College Student | Academic framing. Can use technical terms with brief context. Theory + practical application. |
| Graduate school | Assume strong foundational knowledge. Focus on nuance, trade-offs, edge cases, and deeper implications. Be precise. |

### Job Roles
| Audience | They care about... | Frame explanations around... |
|----------|-------------------|------------------------------|
| Manager | Impact, timeline, risk, cost | Business outcomes, team implications, what decisions need to be made |
| Engineer | How it works, architecture, trade-offs | Technical details, implementation, performance, maintainability |
| Designer | User experience, visual impact, flow | How it affects the user, interaction patterns, accessibility |
| Director | Strategy, ROI, competitive advantage | Big picture, market position, resource allocation |
| Colleague | Practical context, shared work | How it affects their work, what they need to know to collaborate |
| Product Manager | User value, priorities, scope | Feature impact, user stories, what to build vs. skip |

### Relationships
| Audience | Tone | Analogy style |
|----------|------|---------------|
