What is kubernetes-manifest-author?

A guide for writing Kubernetes YAML files, called manifests, that describe how applications should run in Kubernetes, a system for deploying and managing containers.

Use it to create Deployments, StatefulSets, CronJobs, Services, optional Ingress routing, probes, resource requests and limits, security contexts, and ConfigMap or Secret wiring.

It helps cover the operational details that can be missed in a basic deployment, including health checks, resource limits, security settings, and 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.

Model	Per session	Once invoked
Fable 5.1	$0.00114	$0.01579

Security

Grade A, and why

kubernetes-manifest-author 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate_manifest.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Kubernetes Manifest Author

Overview

Produce correct, secure, and reliable Kubernetes YAML for deploying stateless and stateful workloads. This skill turns an application description into a complete manifest set: workload (Deployment/StatefulSet/CronJob), Service, optional Ingress, probes, resource governance, security context hardening, and configuration wiring.

Keywords: kubernetes, k8s, manifest, yaml, deployment, statefulset, service, ingress, liveness probe, readiness probe, startup probe, resources requests limits, securityContext, runAsNonRoot, podSecurityStandards, HPA, autoscaling, ConfigMap, Secret, PodDisruptionBudget, rollout, kubectl, helm, kustomize.

This skill is opinionated toward the restricted Pod Security Standard and production SRE defaults. Loosen only when the user has a concrete reason.

Workflow

Gather the workload shape. Determine: container image + tag (never :latest), listening port(s), stateless vs stateful, replica count, environment/config inputs, secrets, and exposure (cluster-internal, Ingress, LoadBalancer). If the user omits something, apply the safe defaults in references/best-practices.md and state the assumption.
Pick the workload kind using the decision table below. Most web/API services are Deployment.
Author the workload manifest. Start from templates/deployment.yaml. Always fill in: explicit labels, image with pinned tag, resource requests AND limits, all three probe types where appropriate, a hardened securityContext, and a RollingUpdate strategy.
Add the Service. Use templates/service.yaml. Match selector to the Pod template labels exactly. Default to ClusterIP; use LoadBalancer/NodePort only when externally requested.
Add exposure and resilience extras as needed: Ingress, HorizontalPodAutoscaler, PodDisruptionBudget, ConfigMap/Secret. See references/resource-catalog.md.
Wire configuration. Inject config via envFrom/env (ConfigMap) and secrets via secretKeyRef or mounted volumes. Never hardcode secrets in the manifest.

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

kubernetes-manifest-author is a skill published in the GitHub repository JayRHa/AgentSkills (5 stars, last pushed 1mo ago), licensed MIT. It adds 114 tokens to every session and 1,579 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
