Generate Twoslash Code Examples

Generates type-rich Twoslash code examples for RSPress documentation pages.

Overview

This skill creates complete, compilable TypeScript code examples with:

1. Full type checking via Twoslash
2. Auto-loaded dependencies from package.json
3. Progressive complexity (basic → advanced)
4. Cut notations to hide boilerplate
5. Proper imports and complete programs

Quick Start

Generate basic usage example:

/rspress-examples effect-type-registry --api=TypeRegistry --scenario=basic

Generate advanced example:

/rspress-examples rspress-plugin-api-extractor --api=PluginConfig --scenario=advanced

Generate error handling example:

/rspress-examples website --api=BlogPost --scenario=error-handling

How It Works

1. Parse Parameters

• module: Module name from design.config.json [REQUIRED]
• --api: API item to demonstrate (class, function, interface) [REQUIRED]
• --scenario: Example scenario (basic, advanced, error-handling, integration) [REQUIRED]
• --output: Output file path (optional)
• --dry-run: Preview without writing (optional)

2. Load Configuration

Reads design.config.json to find module configuration.

Reads rspress.config.ts to determine:

• Available dependencies (autoDetectDependencies)
• Package name and version
• Existing examples structure

3. Read API Documentation

Finds API documentation for the specified item:

• Reads auto-generated API docs
• Extracts signatures, types, parameters
• Identifies related types and interfaces

4. Generate Example Code

Creates complete TypeScript program:

Basic Scenario:

• Minimal working example
• Core functionality demonstrated
• Simple, clear code

Advanced Scenario:

• Complex configuration
• Multiple features combined
• Realistic use case

Error Handling Scenario:

• Try-catch blocks
• Error type handling
• Recovery strategies

Integration Scenario:

• Multiple APIs working together
• Real-world workflow
• Complete solution

5. Add Twoslash Annotations

Enhances code with Twoslash features:

• Hover comments for type inference
• Error annotations for expected errors
• Cut notations to hide boilerplate
• Meta tags for special rendering

6. Validate Compilation

Ensures code compiles:

• All imports resolve
• Types are correct
• No compilation errors
• Twoslash annotations work

7. Insert into Documentation

Updates or creates documentation page:

• Adds example to existing page
• Creates new example page if needed
• Updates navigation metadata
• Adds cross-references

Code Block Structure

All generated examples follow this pattern:

```typescript twoslash vfs
import { API } from "module-name";

// Additional imports as needed

// ---cut-before---
// Boilerplate hidden from users

// Main example code visible to users

// ---cut-after---
// Verification code hidden from users
```

Supporting Documentation

• instructions.md - Detailed generation process
• examples.md - Sample outputs for each scenario

Success Criteria

• ✅ Code compiles without errors
• ✅ All imports are explicit
• ✅ Example demonstrates intended use case
• ✅ Twoslash annotations work
• ✅ Code is properly formatted

Integration Points

• Uses .claude/design/design.config.json
• Reads rspress.config.ts for dependencies
• Reads API docs from {siteDocs}/api/
• Updates documentation pages
