Production patterns for managing complex application state in React without Redux, Zustand, or other state libraries. Includes multi-stage loading, command patterns, refs for performance, and parallel data fetching. Use when building complex UIs with interconnected states, need loading stages and progress tracking, or implementing command patterns.
State Management, Dependency Injection & Navigation
Flutter state management patterns — decision tree for setState, Provider, Riverpod, and BLoC with concrete examples and testing strategies
Load PROACTIVELY when task involves application state, data fetching, or form handling. Use when user says "manage state", "add data fetching", "set up Zustand", "handle form validation", or "add React Query". Covers server state (TanStack Query with caching, optimistic updates), client state (Zustand stores), form state (React Hook Form with Zod validation), URL state (search params, routing), and choosing between state solutions.
State persistence patterns for autonomous-dev including JSON persistence, atomic writes, file locking, crash recovery, and state versioning. Use when implementing stateful libraries or features requiring persistent state.
Append-only task record convention for Loom. Use when reading or writing per-task records under `.agents/tasks/<task-id>/`, when another skill needs to log a lifecycle milestone (saved, decision, readiness, blocker, done), when the user asks about an existing task's status or progress, or when checking task records for drift via the linter. Do NOT trigger for creating new tasks (that is `task-brief`'s job), for general docs/planning unrelated to a task directory, or for historical questions about the retired `task-state-management` system.
React composition patterns that scale. Use when refactoring components with boolean prop proliferation, building flexible component libraries, or designing reusable APIs. Triggers on tasks involving compound components, render props, context providers, or component architecture. Includes React 19 API changes.
Write, review, or improve SwiftUI code following best practices for state management, view composition, performance, modern APIs, Swift concurrency, and iOS 26+ Liquid Glass adoption. Use when building new SwiftUI features, refactoring existing views, reviewing code quality, or adopting modern SwiftUI patterns.
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
Manage server state in React with TanStack Query v5. Covers useMutationState, simplified optimistic updates, throwOnError, network mode (offline/PWA), and infiniteQueryOptions. Use when setting up data fetching, fixing v4→v5 migration errors (object syntax, gcTime, isPending, keepPreviousData), or debugging SSR/hydration issues with streaming server components.
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management", or needs ADK (Agent Development Kit) Python API patterns and code examples. Part of the Google ADK skills suite. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, and state management. Do NOT use for creating new projects (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
