devops-skills: Instructions file for Codex

AGENTS.md

devops-skills AGENTS.md is an instructions file for Codex, OpenCode from arjunprabhulal/devops-skills. It costs 2,168 tokens per session, scanned A, original, MIT.

Repository instructions for maintaining a collection of DevOps agent skills. Each skill is an on-demand instruction set stored in its own SKILL.md file.

In plain words
What is it for?
It is for creating or reviewing skills in the repository, including their frontmatter, introductory principle, numbered sections, completion checks, and final report.
Why use it?
It gives contributors clear rules for skill structure, descriptions, cross-references, implementation sections, and reporting before changes are committed.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions .claude-plugin; mentions Claude Code; mentions AGENTS.md.

This is arjunprabhulal/devops-skills's own configuration. It tells Codex and OpenCode how to work on devops-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything devops-skills configures →

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-skills AGENTS.md 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 1mo 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.

AGENTS.md

Guidance for AI agents (and humans) working in this repository: the required shape of a skill, the workflow for changing one, and the reasoning behind both. README.md describes what the collection contains and how to install it.

What this repo is

A collection of 88 DevOps Agent Skills across 15 categories. Each skill is a single SKILL.md under skills/<category>/<skill-name>/, loaded on demand when a matching task appears.

The shape of every skill

  1. Frontmatter — exactly three keys: name (must equal the folder name), description (one paragraph with concrete "Use this whenever…" triggers and "For X use sibling" cross-references), and license: MIT.
  2. Intro — one or two paragraphs framing the core principle, ending in a single bold principle line.
  3. 5–6 numbered ## N. Imperative heading sections — each explains the why, may carry at most one or two code blocks or tables total, and ends with a concrete Done when: line.
  4. ## Report — closes by stating the key decisions and, explicitly, the honest remaining gap.

Rules

  • One responsibility per skill. Cross-reference siblings by name instead of repeating them.
  • Be opinionated and explain why. A rule without a reason is not memorable.
  • Principles over vendors. Name tools to illustrate; never tie a skill to one product.
  • No placeholders. Every skill must be complete and technically correct.

Before committing

Run the validator:

python3 scripts/check-skills.py

It checks frontmatter, name/folder match, description length and triggers, the presence of a Report section and Done-when checkpoints, balanced code fences, eval files, reference links, that .claude-plugin/plugin.json matches the skills on disk, and that the Antigravity .agents/skills/ layout is in sync. When you add a skill, add its path to plugin.json and to the README catalogue.

Two layouts, one source

The canonical skills live under skills/<category>/<skill>/ (the Claude Code plugin layout). Google Antigravity discovers skills from a flat .agents/skills/<skill>/ layout, which is generated from the canonical tree and not committed — .agents/ is gitignored. After adding or editing any skill, regenerate it locally:

Changes

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.
