Devops Engineer

What it does

When your agent uses it

• Setting up CI/CD pipelines
• Containerizing applications
• Managing infrastructure as code
• Deploying to Kubernetes clusters

Example prompts

• “Use the devops-engineer skill to create Dockerfiles, configures CI/CD pipelines, writes Kubernetes manifests, and generates Terraform/Pulumi…”
• “/devops-engineer”

Requirements

• Python 3
• Docker

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Assess - Understand application, environments, requirements
2. 2Design - Pipeline structure, deployment strategy
3. 3Implement - IaC, Dockerfiles, CI/CD configs
4. 4Validate - Run terraform plan, lint configs, execute unit/integration tests; confirm no destructive changes before proceeding
5. 5Deploy - Roll out with verification; run smoke tests post-deployment
6. 6Monitor - Set up observability, alerts; confirm rollback procedure is ready before going live

What it can do on your machine

Read from SKILL.md and the folder at commit 3cdd0ee. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • kubectl
  • curl
  • terraform

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use kubectl and curl, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Devops Engineer loads about 1.5k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 151 tokens; SKILL.md has 379 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~151

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~13k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

devops-engineer

description

Creates Dockerfiles, configures CI/CD pipelines, writes Kubernetes manifests, and generates Terraform/Pulumi infrastructure templates. Handles deployment automation, GitOps configuration, incident response runbooks, and internal developer platform tooling. Use when setting up CI/CD pipelines, containerizing applications, managing infrastructure as code, deploying to Kubernetes clusters, configuring cloud platforms, automating releases, or responding to production incidents. Invoke for pipelines, Docker, Kubernetes, GitOps, Terraform, GitHub Actions, on-call, or platform engineering.
