# Interactive Playgrounds and Demo Environments

## Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

## When to Use

Use this skill when you need design and build interactive playgrounds that let developers experience your product without commitment. This skill covers playground architecture, pre-populated examples, embedding strategies, gating decisions, and converting playground users to signups. Trigger phrases: "developer...


Let developers experience your product before they commit. A great playground removes the biggest barrier to adoption: uncertainty about whether your product solves their problem.

## Pre-Populated Examples

### Example Selection Strategy

Choose examples that:
1. **Show core value** in 30 seconds
2. **Solve real problems** developers have
3. **Demonstrate differentiation** from competitors
4. **Scale in complexity** from simple to advanced

### Example Categories

**"Hello World" Example**
- Simplest possible use of your API
- Should work with zero modification
- Proves the system is working

```javascript
// Example: Text Analysis API
const result = await api.analyze("Hello, world!");
// Output: { words: 2, characters: 13 }
```

**"Aha Moment" Example**
- Shows unique capability of your product
- Creates the "wow, that was easy" reaction
- This is your most important example

```javascript
// Example: Shows AI doing something impressive
const result = await api.summarize(longArticle);
// Output: A perfect 3-sentence summary
```

**"Real Use Case" Examples**
- Actual scenarios developers encounter
- Shows how to solve specific problems
- Multiple examples for different use cases

```javascript
// Example 1: E-commerce - Analyze product reviews
// Example 2: Support - Classify incoming tickets
// Example 3: Social - Detect spam comments
```

**"Integration" Examples**
- Shows product working with popular tools
- Addresses "will this work with my stack?" concern

```javascript
// Example: Integration with Express.js
app.post('/analyze', async (req, res) => {
  const result = await api.analyze(req.body.text);
  res.json(result);
});
```

### Example Quality Checklist

- [ ] Example runs without modification
- [ ] Output is interesting/impressive
- [ ] Code follows language best practices
- [ ] Comments explain what's happening
- [ ] Real-world use case is obvious
- [ ] Leads to natural "what else can it do?" curiosity

## Limitations

- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
