cloud-native-ref: Instructions file for Codex

AGENTS.md

cloud-native-ref AGENTS.md is an instructions file for Codex, OpenCode from Smana/cloud-native-ref. It costs 2,299 tokens per session, scanned A, original, Apache-2.0.

A repository instruction guide for a cloud platform built with tools that provision and operate services on AWS and Google Cloud. It explains which rules apply globally and which additional rules apply inside each directory.

In plain words
What is it for?
Use it when changing cloud infrastructure, deployment configuration, security settings, observability, applications, scripts, or architecture documents.
Why use it?
It keeps changes consistent with the repository's deployment, security, infrastructure, and validation practices. Reading the nearest guide helps avoid applying the wrong rules to a directory.

Instructions file for CodexOpenCode

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

This is Smana/cloud-native-ref's own configuration. It tells Codex and OpenCode how to work on cloud-native-ref 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 cloud-native-ref 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

cloud-native-ref 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cloud-native-ref

A production-grade cloud-native platform reference: GitOps on AWS EKS and GCP GKE, built with OpenTofu, Terramate, Flux, Crossplane, Cilium and OpenBao.

Instructions are scoped by directory. This file holds what applies everywhere; each directory below carries its own AGENTS.md that loads when you work in it. Read the nearest one before changing anything there.

Directory Covers
opentofu/ Terramate orchestration, TM_* gates, EKS/GKE two-stage bootstrap
infrastructure/ Crossplane claims and traps, Cilium, Gateway API, Tailscale
security/ OpenBao, PKI, IAM, CiliumNetworkPolicy authoring
observability/ VictoriaLogs LogsQL, VictoriaMetrics, Grafana dashboards
clusters/ Flux dependency graph, variable substitution, the AI umbrellas and their opt-in gates
apps/ App claims, Atlas database migrations
scripts/ What each validator actually checks, and what it cannot
docs/architecture/ Diagram authoring and the icon library
docs/superpowers/ Design and plan artifacts, and the gate at each phase

The AI platform lives in Smana/ai-native-ref

The LLM platform, the AI gateway and the agent factory — manifests, docs, runbooks, specs — live in Smana/ai-native-ref, documented at airef.ogenki.io (ADR-0057). This repository is their host.

Piece Where
Pin flux/sources/ocirepo-ai-native-ref.yaml — tag + digest, cosign-verified
Umbrellas clusters/<cluster>/{ai-gateway,llm-platform,agent-platform}.yaml; children come from the artifact
Overlay task ai:overlay lays the pinned artifact over the paths listed in scripts/ci/flux-schema/ai-boundary.yaml; all gitignored, never committed
Host contract design §2, copied to ai-native-ref's HOST-CONTRACT.md; a change lands in both

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.
