AGENTS.md

HomeLab AGENTS.md is an instructions file for Codex, OpenCode from ArthurVardevanyan/HomeLab. It costs 2,814 tokens per session, scanned A, original, Unlicense.

Agent instructions for a repository that manages OKD and MicroShift clusters, which are Kubernetes-based systems for running applications. It uses ArgoCD for Git-based deployments and Ansible for server setup.

In plain words
What is it for?
Use them when working on Kubernetes manifests, cluster installation, server provisioning, containers, GitOps deployments, or the project’s main management script.
Why use it?
They explain the repository layout and the required tools and procedures before an agent changes infrastructure or application configuration.

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

HomeLab 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 7d 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.

Agent Instructions

This file is the entry point for AI agents working in this repository. It mirrors the HomeLab skill at SKILL.md. Read both before acting.

TL;DR

  • This repo manages a bare-metal OKD cluster (3 control-plane + workers + GPU node) and an edge MicroShift node (Raspberry Pi).
  • Applications are deployed via ArgoCD GitOps from kubernetes/.
  • Bare-metal and VM provisioning is via Ansible (ansible/) and the OKD agent-based installer (okd/).
  • The wrapper script main.bash is the primary developer entry point for Ansible, VM provisioning, and OKD cluster management.
  • Kubernetes manifest, Helm, and Kustomize tasks must follow the Kubernetes (KubeShark) skill.

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.
