Generating CRDs from typed schemas (zod / TypeBox / Valibot / hand-written JSON Schema) looks straightforward — convert to OpenAPI v3, embed as openAPIV3Schema, done. It isn't. CRDs use a subset of OpenAPI v3 plus k8s-specific extensions ("Structural Schema"), and several common JSON-Schema features are silently incompatible. Plus there are two non-schema gotchas (status subresource, metadata prohibition) that don't show up until you try to use the CRD.
k8s-crd-from-typed-schema is a community-contributed Claude Code skill in the devops sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/crd-from-typed-schema/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when generating Kubernetes CustomResourceDefinitions from a typed schema source (zod / TypeBox / Valibot / json-schema). Covers the Structural Schema dialect's restrictions, the /status subresource trap, the metadata-prohibition rule, and plural inflection — the four pitfalls that bite on first attempt.
The k8s-crd-from-typed-schema Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 93,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
