# CI/CD Engineer Sub-Skill

**Communication: User's language. Config/code: English.**

## Purpose

Manages CI/CD pipelines, monitoring, observability, security, and operational excellence. Covers GitHub Actions, GitLab CI, Jenkins, ArgoCD, GitOps, Prometheus, Grafana, and modern DevOps practices.

## Context Discovery

### Auto-Investigation

Detect existing CI/CD and monitoring from project:

| Signal | How to Check | What It Tells Us |
|--------|--------------|------------------|
| GitHub Actions | `Glob("**/.github/workflows/*.yml")` | GitHub CI/CD |
| GitLab CI | `Glob("**/.gitlab-ci.yml")` | GitLab pipelines |
| Jenkins | `Glob("**/Jenkinsfile")` | Jenkins pipelines |
| ArgoCD | `Glob("**/argocd/*")` or `Grep("argocd")` | GitOps deployment |
| Prometheus | `Glob("**/prometheus*.yml")` | Metrics collection |
| Grafana | `Glob("**/grafana/*")` or `Grep("grafana")` | Dashboards setup |
| ELK/Loki | `Grep("elasticsearch\\|logstash\\|loki")` | Log aggregation |
| Secrets | `Glob("**/vault/*")` or `Grep("sealed-secrets")` | Secrets management |
| SSL certs | `Glob("**/cert-manager/*")` or `Grep("letsencrypt")` | TLS automation |

**Read existing CI/CD setup:**
- Workflow files for pipeline stages
- Prometheus/Grafana configs for monitoring
- Secrets management approach
- Deployment strategies (blue-green, canary)

### Discovery Questions

    description: "Prometheus, Grafana, ELK, alerts"
  - label: "Security (secrets, SSL, scanning)"
    description: "Vault, sealed secrets, TLS, SAST/DAST"
```

#### Q2: Deployment Platform

```yaml
question: "Where are you deploying?"
header: "Platform"
multiSelect: false
options:
  - label: "Kubernetes cluster"

  - label: "VMs or bare metal"
    description: "Traditional deployment with Ansible or scripts"
  - label: "Serverless (Lambda, Cloud Functions)"
    description: "FaaS deployment pipelines"
```

#### Q3: Observability Maturity

```yaml
question: "What's your monitoring setup?"
header: "Observability"
multiSelect: false
options:
  - label: "No monitoring yet"
    description: "Need metrics, logs, and alerting from scratch"
  - label: "Basic monitoring (logs, uptime)"
    description: "Have logs but need metrics and dashboards"
  - label: "Metrics + logs (need optimization)"
    description: "Have Prometheus/Grafana but need SLOs, cost optimization"
  - label: "Full observability (traces + advanced)"
    description: "OpenTelemetry, distributed tracing, AIOps"
```
