kube-agents: Instructions file for Codex

AGENTS.md

kube-agents AGENTS.md is an instructions file for Codex, OpenCode from gke-labs/kube-agents. It costs 5,689 tokens per session, scanned A, original, Apache-2.0.

A set of repository instructions for kube-agents, a Kubernetes agent system for managing Google Kubernetes Engine environments.

In plain words
What is it for?
Use it when modifying agent configurations, understanding the chat, platform, and cluster profiles, locating tests, or integrating Kubernetes and GKE operations.
Why use it?
It explains the project layout and separates source agent blueprints from runtime profiles and review skills, which helps prevent changes in the wrong directory.

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 gke-labs/kube-agents's own configuration. It tells Codex and OpenCode how to work on kube-agents 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 kube-agents 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

kube-agents 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 3d 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

Project Overview

This repository contains the Kubernetes Agentic Harness (kube-agents): agent configurations, personas, and skills for managing Kubernetes/GKE operations.

Repository Layout

  • agents/: Source of truth for agent blueprints (personas and skills).
    • chat/: The Planning Agent front door: the default Hermes profile that receives chat ingress, plans the work, and delegates each piece to a specialist.
    • platform/: Configuration for the Platform Agent, scaffolded at pod startup into the platform profile.
    • cluster/: The Cluster Agent profile template (persona, scoped config, runtime-debugging skills), which the Platform Agent scaffolds into per-cluster Hermes profiles at runtime; not deployed directly.
    • contributor/: The contributor-agent protocol: the claim/PR/review/escalation loop for external bots (e.g. Kyber, Codebot Robot) coordinating over GitHub alone. Not a runtime blueprint; not shipped.
  • .agents/skills/: Repository-level skills, not shipped in the agent images: review skills (adversarial, security, docs-drift, skill quality) run against pull requests and clusters, review-preflight runs the pre-PR set in a context that did not write the change, the install-/uninstall-/upgrade-kube-agents lifecycle skills drive the installer scripts, and edit-mirrored-skill edits mirrored gke-* skills.
  • .agents/rules/: Repository-level rules, one file per family: code (core_engineering.md), workflows (github_actions.md), pre-PR passes (pre_pr_review.md), eval-driven development (eval_driven_development.md), docs (documentation.md).
  • a2a/: bus Go module: wire library, a2a topics CLI (docs/designs/spec-a2a-payloads.md), gateway, auth-callout, persona/ (bus content), lib/persona/ (persona format).
  • charts/: Canonical Helm chart (kube-agents) deploying the operator and profiles.
  • terraform/: Reusable Terraform modules (gke-cluster, kube-agents-iam, kube-agents-scope-resolver, chat-pubsub, github-minter, gke-backup-plan, drift-pubsub), plus examples/full-install/, the single-apply composition that installs the Helm chart on top.
  • deploy/: Dockerfile, Kustomize bases, shared runtime assets.
  • docs/: Documentation.
    • site/: The published site (Astro + Starlight), the canonical home for user-facing docs.
    • architecture/: The end-state specification (01–09): the target, not what ships today.
    • designs/: Per-feature design documents.
  • k8s-operator/: Go/Kubebuilder operator reconciling PlatformAgent resources.
  • scripts/: Repository tooling: installer/ (shared by the front doors), dev/, release/.
  • examples/: LiteLLM provider configs, vLLM serving, inference replay.
  • bench/: Evaluation harness running kubernetes-sigs/devops-bench against the Platform Agent.
  • images.json: Inventory of every container image an install pulls, with its upstream reference and pin; read by make mirror-images, the kustomize deploy targets, and the docs generator.
  • INSTALL.md: Installation guide.
  • README.md: Project overview.

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.
