Anthropic Production Checklist

Overview

Before going live with a Claude-powered app, verify every item below.

Authentication & Security

• API key stored in secrets manager (not in code or env file on disk)
• Key rotated — not the same one used during development
• Server-side only — no key exposed to client/browser
• Per-user rate limiting in place
• Input validation: max length, content filtering
• System prompt includes injection guardrails

Output

• All checklist items verified (authentication, error handling, streaming, cost, monitoring, reliability, content, performance)
• Production API key configured with appropriate spending limits
• Monitoring and alerting in place
• Fallback behavior tested for API outages

Error Handling

• All Anthropic API calls wrapped in try/catch
• RateLimitError (429) → backoff and retry
• OverloadedError (529) → fallback model or queue
• AuthenticationError (401) → alert team, don't retry
• InvalidRequestError (400) → log and fix, don't retry
• Network errors → retry with backoff
• Request IDs logged for every error (for support tickets)

Streaming

• Using client.messages.stream() for user-facing responses
• Stream errors handled (connection drops, incomplete responses)
• stop_reason checked: end_turn vs max_tokens (incomplete)

Cost Controls

• max_tokens set to realistic values (not 4096 for short answers)
• Correct model for each task (Haiku for simple, Sonnet for balanced)
• Prompt caching enabled for repeated system prompts
• Usage logging in place — tracking tokens and cost per request
• Spending alerts set in Anthropic console

Monitoring

• Response latency tracked (TTFT and total)
• Token usage tracked (input/output per request)
• Error rates dashboarded (by error type)
• Anthropic status page monitored (status.anthropic.com)

Reliability

• SDK maxRetries set (default 2 is fine for most)
• Timeout configured for your use case (timeout option)
• Single client instance reused (not created per request)
• Graceful degradation if Claude is down (cached responses, fallback)

Content & Compliance

• System prompt tested against edge cases and adversarial inputs
• Output validated before showing to users (JSON parsing, length)
• Data retention settings configured in Anthropic console
• No unnecessary PII in prompts
• Usage policy compliance (Anthropic's Acceptable Use Policy)

Performance

• p95 latency acceptable for your UX
• Prompt caching for latency-sensitive paths
• Parallel requests where possible (Promise.all)
• Client-side streaming UI implemented

Examples

Each section above is a verifiable checklist. Work through Authentication & Security, Error Handling, Streaming, Cost Controls, Monitoring, Reliability, Content & Compliance, and Performance sections.

Resources

• API Best Practices
• Error Handling
• Rate Limits
• Acceptable Use Policy

Next Steps

See clade-observability for monitoring setup.

Prerequisites

• All other anthropic skills reviewed
• Application feature-complete and tested locally
• Production API key created (separate from dev)
• Deployment platform selected

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

Run your test suite to confirm the integration works correctly.
