Clade Multi Env Setup

Anthropic Multi-Environment Setup

Overview

Use different API keys, models, and limits across dev/staging/prod.

Environment Configuration

// config/anthropic.ts
interface AnthropicConfig {
  apiKey: string;
  model: string;
  maxTokens: number;
  maxRetries: number;
}

const configs: Record<string, AnthropicConfig> = {
  development: {
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: 'claude-haiku-4-5-20251001', // Cheap for dev
    maxTokens: 256,
    maxRetries: 1,
  },
  staging: {
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: 'claude-sonnet-4-20250514',
    maxTokens: 1024,
    maxRetries: 2,
  },
  production: {
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: 'claude-sonnet-4-20250514',
    maxTokens: 4096,
    maxRetries: 3,
  },
};

export const config = configs[process.env.NODE_ENV || 'development'];

Separate API Keys Per Environment

Use different Anthropic API keys for each environment:

• Dev key: Low tier, spending alerts at $10
• Staging key: Medium tier, spending alerts at $50
• Prod key: Highest tier, spending alerts at usage baseline + 50%

# .env.development
ANTHROPIC_API_KEY=sk-ant-dev-...

# .env.staging
ANTHROPIC_API_KEY=sk-ant-staging-...

# .env.production
ANTHROPIC_API_KEY=sk-ant-prod-...

Model Selection Strategy

Output

• Environment-specific Anthropic configuration (model, maxTokens, maxRetries)
• Separate API keys per environment with appropriate tier limits
• Spending alerts configured per environment
• Dev using Haiku (cheap), staging matching prod (Sonnet), prod using Sonnet/Opus

Error Handling

Examples

Prerequisites

• Completed clade-install-auth
• Multiple environments (dev/staging/prod) configured
• Separate Anthropic API keys created per environment

Instructions

Step 1: Review the patterns below

Each section contains production-ready code examples. Copy and adapt them to your use case.

Step 2: Apply to your codebase

Integrate the patterns that match your requirements. Test each change individually.

Step 3: Verify
