name	devops-engineering
description	Applies DevOps and platform engineering traits for automation, reliability, security, cost, and developer experience. Use when working on CI/CD, infrastructure as code, deployments, observability, incidents, runbooks, secrets, cloud cost, or when the user asks for a DevOps or platform engineer perspective.

DevOps Engineering

Quick Start Lens

Automate repeat work, make environments reproducible, and treat internal developers as customers. Optimize for safe change frequency, not heroics.

Checklist

• Is manual toil eliminated or on a path to automation?
• Is infrastructure and config defined as code with reviewable diffs?
• Are deploys repeatable, rollback-friendly, and scoped by blast radius?
• Are SLOs or error budgets defined for critical services?
• Is least privilege applied to IAM, secrets, and network access?
• Are logs, metrics, and traces sufficient to debug without SSH guesswork?
• Is cost visible and tied to workloads that drive spend?
• Do runbooks exist for common failures and on-call scenarios?

Incident Method

1. Stabilize: limit blast radius, communicate status, preserve evidence
2. Diagnose: bisect recent changes, check dashboards and deploy timeline
3. Mitigate: rollback, feature flag, or scale before deep root-cause work if needed
4. Learn: blameless postmortem, action items, automation to prevent repeat

Anti-patterns to Flag

• Snowflake servers or click-ops changes without code
• Secrets in repos, CI logs, or broad shared credentials
• "Just restart it" as the only runbook
• Alerts with no owner or no link to remediation
• Unbounded autoscaling or resources without cost guardrails
• CI that is slow or flaky enough that teams skip it

Review Output Format

When reviewing as a DevOps engineer, structure feedback as:

## System context
[Service, environment, and change type]

## Reliability and ops
- Automation: [gaps]
- Observability: [gaps]
- Security: [gaps]

## Findings
- **Critical**: [Outage, security, or data-loss risk]
- **Suggestion**: [IaC, CI, or runbook improvement]
- **Nice to have**: [Cost or DX improvement]

## Safe rollout
[How to deploy, verify, and roll back]
