Agent Skills: OpenRouter Production Checklist

OpenRouter Production Checklist

Overview

A comprehensive production readiness checklist for OpenRouter integrations covering security, reliability, observability, cost management, and operational procedures. Each item includes the specific API endpoint or configuration needed to verify compliance.

Security Checklist

SECURITY = {
    "api_key_storage": {
        "check": "API keys stored in secrets manager (not .env files on disk)",
        "verify": "grep -r 'sk-or-v1-' --include='*.py' --include='*.ts' . | grep -v node_modules",
        "pass": "Zero matches",
    },
    "key_rotation": {
        "check": "Keys rotated on 90-day schedule",
        "verify": "Check key creation dates in OpenRouter dashboard",
        "api": "GET /api/v1/keys (management key)",
    },
    "credit_limits": {
        "check": "Per-key credit limits set to isolate blast radius",
        "verify": "curl -s https://openrouter.ai/api/v1/auth/key -H 'Authorization: Bearer $KEY' | jq '.data.limit'",
        "pass": "Non-null limit value",
    },
    "secret_scanning": {
        "check": "CI pipeline includes secret scanning (gitleaks, trufflehog)",
        "verify": "Check CI config for secret scanning step",
    },
    "https_enforced": {
        "check": "All requests use https://openrouter.ai/api/v1",
        "verify": "Grep codebase for 'http://openrouter' (should be zero)",
    },
}

Reliability Checklist

RELIABILITY = {
    "fallback_models": {
        "check": "Fallback chain configured for critical models",
        "config": """extra_body={"models": ["primary", "secondary", "tertiary"], "route": "fallback"}""",
    },

        "check": "Retry with exponential backoff for 429 and 5xx errors",
        "config": "OpenAI SDK max_retries=3 (built-in backoff)",
    },
    "timeouts": {

    "circuit_breaker": {
        "check": "Circuit breaker on primary model (3 failures → fallback)",
        "verify": "Review client wrapper for circuit breaker pattern",
    },
    "max_tokens": {
        "check": "max_tokens set on EVERY request",
        "verify": "Grep codebase for .create( calls without max_tokens",
    },
}

Observability Checklist

OBSERVABILITY = {
    "structured_logging": {
        "check": "Every API call logged with generation_id, model, latency, tokens, cost",
        "fields": ["timestamp", "generation_id", "model", "latency_ms", "prompt_tokens",
                   "completion_tokens", "cost", "status", "user_id"],
    },
    "error_alerting": {
        "check": "Alerts on error rate spikes (>5% over 5 min window)",
        "metric": "count(status=error) / count(*) over sliding 5min window",
    },
    "latency_monitoring": {
        "check": "P50 and P95 latency tracked per model",
        "threshold": "P95 < 10s for standard models, P95 < 30s for reasoning models",
    },
    "cost_tracking": {
        "check": "Daily cost tracked and compared to budget",
        "api": "GET /api/v1/generation?id={gen_id} for exact per-request cost",
    },
    "credit_balance_alert": {
        "check": "Alert when credits drop below threshold",
        "api": "GET /api/v1/auth/key → .data.usage vs .data.limit",
    },
}

Pre-Launch Validation Script

#!/bin/bash
echo "=== OpenRouter Production Readiness ==="
PASS=0; FAIL=0

# 1. Auth works
echo -n "1. API Authentication: "
AUTH=$(curl -s https://openrouter.ai/api/v1/auth/key \
  -H "Authorization: Bearer $OPENROUTER_API_KEY" | jq -r '.data.label // "FAIL"')
if [ "$AUTH" != "FAIL" ]; then echo "PASS ($AUTH)"; ((PASS++)); else echo "FAIL"; ((FAIL++)); fi

# 2. Credit limit set
echo -n "2. Credit Limit: "
LIMIT=$(curl -s https://openrouter.ai/api/v1/auth/key \
  -H "Authorization: Bearer $OPENROUTER_API_KEY" | jq -r '.data.limit // "NONE"')
if [ "$LIMIT" != "NONE" ] && [ "$LIMIT" != "null" ]; then
  echo "PASS (\$$LIMIT)"; ((PASS++))
else echo "WARN (no limit set)"; ((FAIL++)); fi

# 3. Primary model available
echo -n "3. Primary Model Available: "
MODEL="anthropic/claude-3.5-sonnet"
EXISTS=$(curl -s https://openrouter.ai/api/v1/models | jq --arg m "$MODEL" '[.data[] | select(.id == $m)] | length')
if [ "$EXISTS" -gt 0 ]; then echo "PASS ($MODEL)"; ((PASS++)); else echo "FAIL"; ((FAIL++)); fi

# 4. Test request succeeds
echo -n "4. Test Request: "
TEST=$(curl -s https://openrouter.ai/api/v1/chat/completions \
  -H "Authorization: Bearer $OPENROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"openai/gpt-4o-mini","messages":[{"role":"user","content":"hi"}],"max_tokens":1}' \
  | jq -r '.choices[0].message.content // "FAIL"')
if [ "$TEST" != "FAIL" ]; then echo "PASS"; ((PASS++)); else echo "FAIL"; ((FAIL++)); fi

# 5. No hardcoded keys
echo -n "5. No Hardcoded Keys: "
KEYS=$(grep -r "sk-or-v1-" --include="*.py" --include="*.ts" --include="*.js" . 2>/dev/null | grep -v node_modules | grep -v ".env" | wc -l)
if [ "$KEYS" -eq 0 ]; then echo "PASS"; ((PASS++)); else echo "FAIL ($KEYS found)"; ((FAIL++)); fi

echo ""
echo "Results: $PASS passed, $FAIL failed"
[ $FAIL -eq 0 ] && echo "READY FOR PRODUCTION" || echo "FIX FAILURES BEFORE LAUNCH"

Error Handling

| Error | Cause | Fix | |-------|-------|-----| | Production key exposed | Key logged or committed | Rotate immediately; deploy from secrets manager | | No fallback configured | Primary model goes down | Add models array with route: "fallback" | | Missing monitoring | Errors go undetected | Set up alerting before launch | | No max_tokens | Runaway completion costs | Add max_tokens to every request |

Enterprise Considerations

• Run the validation script in CI as a pre-deploy gate
• Set up runbooks for common failure scenarios: rate limiting, credit exhaustion, provider outage
• Load test at 2x expected peak traffic to validate rate limits and fallback behavior
• Document escalation paths: when to contact OpenRouter support vs handle internally
• Review and update this checklist quarterly as OpenRouter adds features
• Keep a "break glass" procedure for emergency key rotation
