TanStack Form is a headless form state manager, not a UI component library. You provide your own inputs and handle their events; TanStack Form manages validation, state, and submission logic.

When to use: Complex multi-step forms, reusable form patterns, dynamic field arrays, cross-field validation, async server validation, forms requiring fine-grained performance optimization.

When NOT to use: Simple forms with native HTML validation (use plain form elements), server-only validation (use Server Actions), purely static forms with no validation.

TanStack Form v1 用於 React 的無頭表單狀態管理。涵蓋欄位驗證（同步/非同步、去抖動）、表單提交、陣列欄位、連結欄位、表單組合模式和標準架構整合（Zod、Valibot、ArkType、Yup）。 在建立具有複雜驗證的表單、實作可重複使用表單元件、處理動態欄位清單、管理表單狀態或整合驗證庫時使用。 來源：oakoss/agent-skills。
