What this skill does


# Operations

Production readiness evaluation focused on resilience, observability, and incident response.

## Resilience

### Failure Modes

- What can fail? List all external dependencies
- Blast radius: If X fails, what else breaks?
- Graceful degradation: Partial failure ≠ total failure?

### Patterns

| Pattern | Purpose | Check |
|---------|---------|-------|
| **Timeouts** | Prevent hung connections | Every external call has one? |
| **Circuit Breaker** | Stop cascading failures | On critical paths? |
| **Bulkhead** | Isolate failures | Separate thread pools? |
| **Retry** | Handle transient failures | With backoff? Bounded? |

## Observability

### The RED Method

| Metric | What | Why |
|--------|------|-----|
| **R**ate | Requests per second | Traffic understanding |
| **E**rrors | Failed requests | Problem detection |
| **D**uration | Latency distribution | Performance tracking |

### Logging

- Structured (JSON, not free text)
- Correlation IDs across services
- Appropriate levels (not everything is ERROR)
- PII redaction

### Tracing

- Distributed tracing enabled?
- Spans for all external calls?
- Context propagation working?

## Capacity

- **Scaling**: Horizontal preferred, auto-scaling configured?
- **Limits**: Memory, CPU, connections all bounded?
- **Backpressure**: What happens at 2x load? 10x?
- **Rate Limiting**: Per-tenant/client quotas?

## Security Posture

- **Secrets**: In vault, not env vars or code
- **Network**: Least privilege, mTLS where possible
- **Dependencies**: Vulnerability scanning in CI
- **Access**: Audit logging for sensitive operations

## Incident Readiness

- **Runbooks**: Documented recovery procedures
- **On-call**: Rotation defined, escalation clear
- **Rollback**: One-click, tested regularly
- **Communication**: Status page, stakeholder notification

## Checklist

```
□ All external calls have timeouts
□ Circuit breakers on critical paths
□ Structured logging with correlation IDs
□ RED metrics exposed
□ Alerts are actionable (not noisy)
□ Auto-scaling configured with limits
□ Graceful shutdown implemented
□ Health checks (liveness + readiness)
□ Secrets in vault
□ Runbook exists
□ Rollback tested
```
