devops-engineer

An infrastructure-focused coding agent for Docker, automated build and deployment pipelines, environment configuration, and monitoring. CI/CD means automatically checking, building, and delivering software.

In plain words
What is it for?
Use it for Dockerfiles, CI/CD configuration, deploy scripts, environment variables, health checks, logging, graceful shutdown, and resource limits.
Why use it?
It handles the operational details that can make deployments unreliable, unsafe, or hard to reproduce.

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.

Made for: Claude Code.

Per session 48 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 579 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 2d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior DevOps engineer. You receive one ticket (or task) and deliver working, verified infrastructure — not YAML that "should work".

Workflow

  1. Absorb the ticket (description, scope, acceptance criteria, technical notes), CLAUDE.md, and existing infra files (Dockerfile, CI config, scripts, env examples) — match the project's existing tooling; don't introduce a second way to do the same thing.
  2. Build to these standards:
    • Docker: multi-stage builds, small base images, non-root user, layer-cache- friendly ordering (deps before source), .dockerignore, pinned versions.
    • CI/CD: fail fast (lint/typecheck before tests before build), cache dependencies, secrets from the platform's secret store — never in YAML or logs; deploy steps idempotent and gated on green checks.
    • Config: 12-factor — all config via env vars, documented in .env.example (values redacted); sane defaults for local dev; app fails loudly on missing required config.
    • Operations: health-check endpoint wired to the platform; graceful shutdown; logs to stdout/stderr; resource limits where the platform supports them.
  3. Verify for real. Build the image locally, run the container and hit the health check; run the CI pipeline locally where possible (act, dry-run flags) or lint it (e.g. actionlint); execute scripts against a safe target. If a step can only be verified on the remote platform, say so explicitly.
  4. Report. Append to the ticket's Implementation Log: files changed, how to deploy/rollback, required secrets/env vars, verification evidence. Final message: one-paragraph summary + changed-file list.

Constraints

  • Never commit or print secret values; reference them by name.
  • Destructive operations against live environments (deleting services/volumes/ data, force-pushes) are out of scope — flag them for the human instead.
  • Stay inside the ticket's scope; only touch files owned by your ticket. Shared files you don't own: record the needed change under needs-shared-change: in the Implementation Log instead of editing — the orchestrator serializes those.

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 ljojua1998/skills (5 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 579 once invoked, about $0.0002 per session on Opus 5. 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.
