    Frontend State Management Planners

    Example session with this skill installed

    Plan the state management for a dashboard with a global date filter, a list of orders fetched from an API, and a slide-over panel for editing order details. I'm using React and Tailwind.

    • Read your context and instructions
    • Compiled the frontend state management
    • Generated the UI component

    The state management plan for the Order Dashboard focuses on separating shared navigational context (date filters) from resource-based server state (orders) and ephemeral UI state (edit panel).

    CLICK ORDER → UPDATE URL (ID) → DERIVE DATA → OPEN PANEL → RENDER FORM

    Architecture Recommendation

    Server State: Use a caching hook (like useQuery) for the Orders list to handle loading and error states automatically.
    2. Global Filters: Move the Date Range into the URL. This ensures users can bookmark filtered views.
    3.

    Derived State: Do not store the "Active Order" object in state. Pass the Order ID via the URL and find the object in the existing Orders list.
    4.

    Form Strategy: Keep the Edit Form state isolated within the SlideOver to prevent the entire dashboard from re-rendering on every keystroke.

    Next steps

    • Implement URL sync for date filters using useSearchParams.
    • Set up a caching layer for the GET /orders endpoint.
    • Create a useOrderForm hook to encapsulate editing logic.

    About this skill

    The problem

    Developers often struggle with bloated global stores, prop drilling, and out-of-sync server data. Deciding where state lives—whether in the URL, a local component, or a global provider—is frequently done inconsistently, leading to bugs and poor performance.

    What it does

    • Classifies every data point by lifetime and ownership to prevent over-globalizing state.
    • Maps complex data flows from user actions to state updates and UI renders.
    • Identifies derived state opportunities to eliminate redundant data synchronization.
    • Defines explicit state transition maps including loading, error, and optimistic update paths.
    • Separates server-side cache concerns from ephemeral client-side UI state.

    Frameworks & tools

    Works with React, Next.js, Vue, Svelte, Angular, and React Native. Library-agnostic recommendations cover Redux, Zustand, React Query, Pinia, and native Context API.

    Why this beats prompting it yourself

    Standard LLMs often default to suggesting Redux or global providers for everything. This skill applies strict architectural decision rules to enforce the principle of least privilege, ensuring state stays local unless global access is technically justified.

    Use cases

    • Refactoring a tangled "God object" global store into modular feature states.
    • Planning the data flow for complex multi-step forms with validation.
    • Designing a robust caching and synchronization strategy for real-time dashboards.
    • Mapping URL-driven state for deep-linking in search and filter interfaces.

    Known limitations

    Does not execute code or perform automated refactoring. Requires clear initial requirements or component structures to be effective.
