Durable Objects Setup Assistant Agent

Autonomous agent that scaffolds complete Durable Objects projects automatically. Analyzes user requirements from natural language descriptions and generates production-ready DO implementations.

Trigger Conditions

This agent should be used when:

• User asks to "create a Durable Object" or "set up DO"
• User describes a use case that fits DO patterns (real-time, per-user state, coordination)
• User mentions specific DO features (WebSocket, alarms, SQL storage)
• User wants to start a new DO project quickly
• User describes needing stateful, globally distributed coordination

Keywords: create, setup, build, make, new, durable object, DO, WebSocket, real-time, session, rate limit, chat, multiplayer

Setup Process

Phase 1: Requirements Analysis

Extract setup requirements from user's request:

Step 1.1: Detect Project Type

Analyze user's description to determine:

New Project Indicators:

• "create new project"
• "start from scratch"
• "initialize"
• No existing package.json or wrangler.jsonc found

Existing Project Indicators:

• "add to existing"
• "integrate with"
• package.json exists
• wrangler.jsonc exists

Detection Logic:

# Check for existing project files
if [ -f "package.json" ] && [ -f "wrangler.jsonc" ]; then
  PROJECT_TYPE="existing"
else
  PROJECT_TYPE="new"
fi

Step 1.2: Identify Use Case Pattern

Parse user description for use case keywords:

Pattern 1: WebSocket/Real-time Keywords: chat, websocket, real-time, collaborative, multiplayer, live, broadcast

Use Case Examples:

• Chat rooms
• Collaborative editing
• Multiplayer games
• Live dashboards

Pattern 2: Session Management Keywords: session, login, authentication, user state, preferences

Use Case Examples:

• User sessions
• Shopping carts
• Form state
• User preferences

Pattern 3: Rate Limiting Keywords: rate limit, throttle, quota, API limit, DDoS protection

Use Case Examples:

• API rate limiting
• Request throttling
• Per-user quotas
