regle

Mandatory pre-commit validation for every Copilot code review on pull requests in the regle monorepo. Always verify commitlint compliance on commit titles and descriptions, pnpm workspace install, lint (vp lint), and format (vp fmt --check). Loaded on every code review — do not skip.

Measure and compare TypeScript memory usage for @regle/core and test typechecks. Use when checking TS server pressure, type-level perf regressions, or before/after heavy generic typing changes.

Core Regle form validation in Vue 3 — setup with `useRegle`, the reactive `r$` object, validation properties, displaying errors, and modifiers. Use when adding or editing Regle forms, binding `v-model` to `r$.$value`, or reading `$error`/`$errors`/`$invalid`/`$validate`/`$reset`. For validation rules see regle-rules; for advanced patterns see regle-advanced.

Advanced Regle form validation patterns — collection validation with `$each`, async rules and `$pending`, server/`externalErrors`, `$reset` options, global config with `defineRegleConfig`, discriminated-union variants, cross-component `useScopedRegle`/`useCollectScope`, `mergeRegles`, and object-level `$self`. Use for arrays of fields, async/server validation, scoped or merged forms, i18n messages, or variant forms. For schema libraries see regle-schemas.

Migrate Vuelidate form validation to Regle. Use when porting forms that import from `@vuelidate/core`/`@vuelidate/validators` or call `useVuelidate` over to `useRegle`/`useScopedRegle`, including rules, validation properties, `v-model` bindings, nested/scoped validation, and parent-child form propagation.

Regle validation rules — built-in rules from `@regle/rules`, custom rules with `createRule`, rule wrappers (`withMessage`, `withParams`, `withAsync`, `withTooltip`), and rule operators (`and`, `or`, `xor`, `not`, `applyIf`, `assignIf`, `pipe`). Use when declaring, customizing, composing, or conditionally applying validation rules in a Regle form. For form setup see regle.

Validate Regle forms with schema libraries via `@regle/schemas` — Zod, Valibot, ArkType, and any Standard Schema spec library using `useRegleSchema`, `useRules`, `refineRules`, and `InferInput`. Use when a form's validation is defined by an external schema instead of `@regle/rules`. For native rules see regle-rules; for form setup see regle.

TypeScript integration for Regle — type-safe validated output (`InferSafeOutput`, `$validate`), inferring state from rules (`InferInput`), typing computed rules (`inferRules`, `RegleComputedRules`), and typing component props (`InferRegleRoot`, `RegleRoot`, `RegleFieldStatus`, `SuperCompatibleRegleRoot`). Use when typing rules schemas, passing `r$` between components, or extracting validated data types.

Vite+ unified toolchain (vp CLI) usage for this project, wrapping Vite, Rolldown, Vitest, tsdown, Oxlint, Oxfmt, and Vite Task. Use when running install/build/test/check/format/lint, working with the `vp` CLI, or validating changes in this repo.

Turborepo monorepo build system guidance. Triggers on: turbo.json, task pipelines, dependsOn, caching, remote cache, the "turbo" CLI, --filter, --affected, CI optimization, environment variables, internal packages, monorepo structure/best practices, and boundaries. Use when user: configures tasks/workflows/pipelines, creates packages, sets up monorepo, shares code between apps, runs changed/affected packages, debugs cache, or has apps/packages directories.

VitePress static site generator powered by Vite and Vue. Use when building documentation sites, configuring themes, or writing Markdown with Vue components.

Bundle TypeScript and JavaScript libraries with blazing-fast speed powered by Rolldown. Use when building libraries, generating type declarations, bundling for multiple formats, or migrating from tsup.
