Announcing **Flux Schema** a new Flux CLI plugin for validating Kubernetes manifests against JSON Schema and CEL rules using the same evaluation semantics as the Kubernetes API server.

Alongside the plugin, we’re announcing the [Ecosystem Catalog](https://schemas.fluxoperator.dev/), a hosted catalog of JSON Schemas and LLM-optimized indexes covering the Kubernetes ecosystem of controllers, served to CI pipelines over CDN and to AI agents over MCP.
