devopsEngineer

A development guide for infrastructure and DevOps work, meaning the automation that builds, tests, packages, and maintains software. It covers GitHub Actions, pre-commit hooks, quality checks, validation scripts, and Python packaging setup.

In plain words
What is it for?
Use it to edit CI/CD workflows, configure pre-commit checks, set up linters and security scanners, create composite GitHub Actions, write validation scripts, and update packaging configuration.
Why use it?
It keeps build and release automation consistent and helps ensure code-quality and security checks run correctly. It also clarifies which files and tasks belong to infrastructure work.

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

devopsEngineer 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate-infra.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Before You Start

Read LEARNED.md first. It contains corrections, preferences, and conventions accumulated from previous sessions. Apply every rule in that file — they override defaults in this skill.

Announce skill usage. Always say "Using: devopsEngineer skill" at the very start of your response before doing any work.

When to Use

  1. Creating or modifying GitHub Actions workflows under .github/workflows/
  2. Configuring pre-commit hooks in .pre-commit-config.yaml
  3. Updating linter/formatter configuration (.pylintrc, Black flags, autoflake args)
  4. Writing or modifying bash validation scripts under .data/skills/*/scripts/
  5. Modifying CI-related sections of pyproject.toml (build system, dev dependencies)
  6. Creating composite actions under .github/actions/

Do NOT Use

  • Python source code (modules, dataclasses, CLI logic) — use backendEngineer
  • NiceGUI UI components/pages (Tailwind, Quasar) — use frontendEngineer
  • Skill system meta-rules (SKILL.md structure, LEARNED.md format) — use skillnir

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.

devopsEngineer is a skill published in the GitHub repository AlirezaSoltaniJazi/Skillnir (7 stars, last pushed 1mo ago), licensed MIT. It adds 107 tokens to every session and 3,228 once invoked, about $0.0005 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.
