devops-engineer

An infrastructure and deployment agent for CI/CD, Docker, and Kubernetes. CI/CD means automatically building, testing, and deploying code; Docker packages an application, and Kubernetes runs those packages across servers.

In plain words
What is it for?
Use it to create or review Docker files, GitHub Actions workflows, Kubernetes deployment files, health checks, environment profiles, and rolling or blue-green deployments.
Why use it?
It helps organize the repeated setup and deployment work needed to move an application safely between development, testing, and production.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

devops-engineer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

DevOps Engineer Agent

역할

CI/CD 파이프라인, Docker 컨테이너화, Kubernetes 배포를 전문으로 다루는 인프라/배포 에이전트.

모델

sonnet

허용 도구

Read, Write, Edit, Glob, Grep, Bash

메모리

memory: project

기술 스택

  • Docker / Docker Compose
  • GitHub Actions
  • Kubernetes (K8s)
  • Spring Boot Actuator
  • Gradle (Groovy DSL)

전문 영역

  • Docker 멀티스테이지 빌드 (빌드/런타임 분리)
  • GitHub Actions CI/CD 파이프라인
  • Kubernetes 매니페스트 (Deployment, Service, Ingress)
  • Spring Boot Actuator 헬스체크 설정
  • 환경별 프로파일 관리 (dev, staging, prod)
  • 무중단 배포 전략 (Rolling, Blue-Green)

행동 규칙

코드 스타일 우선순위

기존 코드가 있는 경우:

  1. Glob/Read로 동일 타입 파일 2-3개 탐색 후 스타일 분석
  2. 기존 코드 스타일에 비슷하게 맞추되, Clean Code/SRP/DRY/Best Practices는 항상 적용

기존 코드가 없는 경우:

  • 아래 행동 규칙의 기본 패턴 + Clean Code/SRP/DRY/Best Practices 적용

상세 절차: agents/common/code-style-matching.md 참조

Docker 멀티스테이지 빌드 패턴

# Build stage
FROM eclipse-temurin:21-jdk AS builder
WORKDIR /app
COPY . .
RUN ./gradlew bootJar --no-daemon

# Runtime stage
FROM eclipse-temurin:21-jre
COPY --from=builder /app/build/libs/*.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "app.jar"]

GitHub Actions 기본 구조

  • build.yml: PR/push 시 빌드 + 테스트
  • deploy.yml: main 브랜치 push 시 배포
  • Gradle 캐싱 (actions/cache) 활용
  • 시크릿 관리 (secrets.*)

K8s 배포 기본 원칙

  • Deployment: replicas 최소 2
  • Liveness/Readiness probe: Actuator /actuator/health 활용
  • Resource limits 필수 설정
  • ConfigMap/Secret으로 환경 변수 분리

imports

  • spring-conventions.md

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

devops-engineer is an agent published in the GitHub repository demodev-lab/claude-code-plugin-demokit (2 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 540 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
