Installation: Getting Started with the TypeScript Clasp Claude Skill

Using with Claude Desktop via MCP

To integrate this Claude Skill into your development environment, you'll need to configure it through the Model Context Protocol (MCP):

1. Locate your Claude configuration file:

   • On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • On Windows: %APPDATA%/Claude/claude_desktop_config.json

2. Add the skill configuration:

{
  "mcpServers": {
    "typescript-clasp": {
      "command": "npx",
      "args": ["-y", "@patrickjs/mcp-server-cursorrules", "typescript-clasp"]
    }
  }
}

3. Restart Claude Desktop to activate the skill.

Using with Cursor or Other IDEs

If you're using Cursor or another IDE that supports custom AI rules:

1. Navigate to the awesome-cursorrules repository
2. Locate the TypeScript clasp rule configuration
3. Copy the rule content into your project's .cursorrules file or IDE settings
4. The AI will now follow TypeScript and clasp best practices automatically

Prerequisites

Before using this skill effectively, ensure you have:

• Node.js and npm installed
• clasp CLI tool (npm install -g @google/clasp)
• A Google account with Apps Script API enabled
• TypeScript knowledge (the skill will help, but basic familiarity helps)

Use Cases: Where the TypeScript Clasp Skill Excels

Use Case 1: Building a Google Sheets Automation with Type Safety

Scenario: You need to create a TypeScript-based script that automatically processes data in Google Sheets, with proper type definitions and error handling.

Example Prompt:

Create a TypeScript Apps Script that reads data from a Google Sheet named 
"Sales Data", calculates monthly totals, and writes the results to a 
"Summary" sheet. Include proper type definitions for the data structures 
and implement error handling for missing sheets.

What the Skill Delivers:

• Fully typed TypeScript code with interfaces for your data models
• Proper clasp project structure with appsscript.json configuration
• Type-safe Google Apps Script API usage
• Deployment instructions using clasp commands
• Error handling that leverages TypeScript's type system

Use Case 2: Creating a Gmail Add-on with Modern Development Workflow

Scenario: You want to build a Gmail add-on using TypeScript with hot-reload development capabilities.

Example Prompt:

Set up a TypeScript clasp project for a Gmail add-on that adds a sidebar 
showing email analytics. Include the project structure, deployment 
configuration, and a development workflow that allows for rapid iteration.

What the Skill Delivers:

• Complete clasp project initialization commands
• TypeScript configuration optimized for Apps Script
• Manifest file (appsscript.json) with Gmail add-on settings
• Watch mode setup for continuous deployment during development
• Best practices for HTML service and client-server communication

Use Case 3: Migrating Legacy Apps Script to TypeScript

Scenario: You have existing JavaScript-based Apps Script code that needs to be converted to TypeScript with proper typing.

Example Prompt:

I have this Google Apps Script function [paste code]. Convert it to 
TypeScript with proper type annotations, refactor it to use modern 
best practices, and show me how to set up the clasp project structure.

What the Skill Delivers:

• Converted TypeScript code with explicit type annotations
• Identification of potential runtime errors caught by TypeScript
• Modern ES6+ syntax improvements
• clasp configuration for deploying the refactored code
• Suggestions for breaking code into maintainable modules
