Use when working with CUE kind definitions, schemas, or versioning in grafana-app-sdk projects (app platform apps). This skill should be used when the user asks to "define a kind", "add a CUE kind", "write a kind schema", "create a CUE schema", "model a resource", "add a new resource type", "edit kinds/", "what is a kind in grafana-app-sdk", "add a version to a kind", or asks about CUE kind structure, versioning, schema fields, validation constraints, or the codegen configuration section. Provides guidance on authoring CUE kind definitions for grafana-app-sdk projects.
Rules and patterns for building React forms with React Hook Form (RHF) and Zod validation. Use this skill whenever the user is creating, editing, or refactoring any React form — including login forms, registration flows, multi-step wizards, dynamic field arrays, or any input component wired to RHF. Also trigger when the user mentions `useForm`, `Controller`, `zodResolver`, `z.object`, schema validation, form state, `useFieldArray`, or `FormProvider`. Trigger even if they just ask "how do I validate this field" or "how do I handle server errors in a form" — this skill covers it all.
Advanced patterns for Regle form validation, including arrays, async, server errors, global config, variants, scoped validation, and schema integration.
