Interactive Playgrounds and Demo Environments

Detailed Guide

Read the detailed guide 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 when designing a developer API playground, its sandbox architecture, sharing, gating or evaluation flow.

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

// 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

// Example: Shows AI doing something impressive
const result = await api.summarize(longArticle);
// Illustrative output shape only; summarize may be inaccurate and needs evaluation.

"Real Use Case" Examples

• Actual scenarios developers encounter
• Shows how to solve specific problems
• Multiple examples for different use cases

// 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

// 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 actually runs in the stated pinned environment, or is clearly labeled pseudocode with missing adapters
• [ ] 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.

api, longArticle, Express setup and service adapters are not bundled. Never expose a privileged API key to editable code or auto-run billable/destructive examples on page load. Use explicit Run, synthetic data, short-lived scoped capabilities and server-enforced budgets.
