home-ops: Instructions file for Codex

AGENTS.md

home-ops AGENTS.md is an instructions file for Codex, OpenCode from Aviator-Coding/home-ops. It costs 4,339 tokens per session, scanned A, original, MIT.

Project instructions for a Home-ops repository that manages a three-node Talos Linux Kubernetes cluster with Flux GitOps. GitOps means storing infrastructure configuration in Git and applying changes from there.

In plain words
What is it for?
Use them when modifying Kubernetes applications, cluster configuration, networking, storage, backups, secrets, or monitoring in this repository.
Why use it?
They give coding agents the repository's structure, technology choices, conventions, and rules so changes fit the existing setup.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

This is Aviator-Coding/home-ops's own configuration. It tells Codex and OpenCode how to work on home-ops 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 home-ops 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

home-ops 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 22d 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.

PROJECT KNOWLEDGE BASE

Home-ops GitOps repo for a 3-node Talos Linux Kubernetes cluster managed by Flux v2. CLAUDE.md is a symlink to this file. Subsystem knowledge lives in skills (SKILL INDEX below); operator detail also in talos/AGENTS.md, bootstrap/AGENTS.md and the runbooks in skill references (SKILL INDEX below; docs/README.md lists the few that live elsewhere).

Core stack: Talos Linux + Flux v2 + Cilium (CNI, BGP LoadBalancer, kube-proxy replacement, no L2 announcements) + Rook-Ceph + External Secrets Operator/1Password + Cloudflare Tunnel + External-DNS (split: network/cloudflare-dns public, network/unifi-dns internal) + kopiur (primary backup; VolSync only on 3 carve-outs) + Gateway API (envoy-internal/envoy-external in network) + kube-prometheus-stack/Loki/Tempo/Grafana/Gatus in monitoring.

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.
