No DevOps & Infrastructure skill matches that.
Where to start
Install the ones that match requests you make every week. Name one with $github-actions-security when you want it for sure; otherwise Codex picks by description.

DevOps & Infrastructure FAQ
How do I install every DevOps & Infrastructure skill at once?
Run curl -fsSL https://codexskills.dev/install.sh | sh -s -- --category devops to put all 40 in ~/.agents/skills/, or add --project to install them into the current repository's .agents/skills/. You can also download the category zip and unpack it yourself.
Does installing 40 skills slow Codex down?
Hardly. At startup Codex sees only each skill's name and description, a few dozen words apiece, and reads a full SKILL.md only when a task needs it. Install the whole category if the work fits; unused skills cost almost nothing.
Which DevOps & Infrastructure skill should I start with?
Start with GitHub Actions Security, Kubernetes Debugging, TLS Certificates. They cover the requests that come up most in this category. Mention one with $github-actions-security to try it.
