Release v1.24.16 - Cloudflare Sandbox Integration with Claude Agent SDK

🎉 Major New Feature: Cloudflare Workers Sandbox

We're excited to announce the complete implementation of Cloudflare Workers Sandbox - a new execution environment for AI-powered code generation alongside our existing E2B sandbox support.

🚀 What's New

Cloudflare Sandbox Implementation

Run AI-generated code using Cloudflare's edge network infrastructure with full agent support.

Quick Start:

npx claude-code-templates@latest --sandbox cloudflare \
  --agent development-team/frontend-developer \
  --prompt "Create a contact form with validation"

Key Features:

✅ Full Agent Support - Use any of 600+ specialized agents
✅ Claude Agent SDK Integration - Powered by @anthropic-ai/claude-agent-sdk v0.1.23
✅ Automatic Agent Loading - Uses settingSources: ['project'] for seamless agent integration
✅ Multi-file Generation - Automatically extracts and saves HTML, CSS, JavaScript files
✅ Timestamped Directories - Files saved to cloudflare-{timestamp}/ for easy organization
✅ Clean Progress Logs - Essential progress indicators without code dumps

🔧 Technical Highlights

Agent SDK Migration (v1.24.15)

Migrated from basic @anthropic-ai/sdk to @anthropic-ai/claude-agent-sdk
Implemented automatic agent loading via settingSources: ['project']
Proper message handling for SDK's result type responses
Agent files automatically downloaded from GitHub to .claude/agents/

Code Generation Workflow

Agent Installation: Downloads specified agents to .claude/agents/
Settings Creation: Generates .claude/settings.json with agent references
Code Generation: Claude generates code using loaded agent expertise
File Extraction: Parses code blocks and extracts individual files
Local Download: Saves files to cloudflare-{timestamp}/ directory

Clean Logging (v1.24.16)

Removed unnecessary code output from console
Simplified file download logs (show only essential progress)
Clean, user-friendly execution feedback

📊 How It Works

# Example execution flow:
npx claude-code-templates@latest --sandbox cloudflare \
  --agent development-team/frontend-developer \
  --prompt "Create a todo list app"

# Output structure:
cloudflare-mgzrzugb/
├── index.html       # Complete HTML structure
├── styles.css       # Modern responsive CSS
└── script.js        # Interactive JavaScript

🆚 Cloudflare vs E2B Sandbox
