What it does

Schema pinning that actually works.

{ }

Autocomplete for any CRD

Full IntelliSense for cert-manager, Cilium, Argo CD, kyverno, and more — pinned to the exact operator version your cluster runs.

spec:
issuerRef:
name: letsencrypt-prod
kind:  
ClusterIssuercert-manager.io/v1
Issuercert-manager.io/v1

✓

Inline validation

Unknown fields, wrong types, missing required keys — flagged as you type.

✕ duration: "9999d"

Does not match format "duration"

✓ duration: "2160h"

🔒

Lockfile pinning

One schemalock.yaml per repo. Pin each CRD group to a version. Everyone validates against the same schema.

⚡

Lazy fetch, local cache

Schemas are downloaded once and cached locally. Works offline. Only the CRDs you actually use are fetched.

⊕

Integrity-verified

Every schema is SHA-256 content-addressed. The extension rejects anything that doesn't match the manifest.

Config

One file. Every CRD.

Drop a schemalock.yaml in your repo. Pin each group to the operator version your cluster runs. Every editor on the team validates against the same schema — no setup, no drift.
