What it does
Nextjs State Management is an agent skill from HoangNguyen0403/agent-skills-standard. Apply best practices for managing URL, server, and client state in Next.js applications. Use when choosing between URL params, SWR/TanStack Query, Zustand, or Context for state, or when fixing hydration mismatches from localStorage.
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `evals/evals.json`, `references/implementation.md` and `references/redux.md`).
It sits in Frontend & Design, covering State management. It works with Next.js, Zustand, TanStack and Redux. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.
When your agent uses it
- Choosing between URL params
- SWR/TanStack Query
- Context for state
- Fixing hydration mismatches from localStorage
Example prompts
- “/nextjs-state-management”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Shareable/persistent? Use URL state (useSearchParams + useRouter).
- Server data? Use SWR or TanStack Query. Never sync into useState.
- Complex client UI? Use Zustand (in 'use client' only) or Jotai.
- Simple local? Use useState. Colocate as close to consumer as possible.
What it can do on your machine
Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nextjs State Management loads about 603 tokens when it runs, and up to ~4.2k if it reads all its reference files. Until then it costs about 64 tokens; SKILL.md has 219 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Apply best practices for managing URL, server, and client state in Next.js applications. Use when choosing between URL params, SWR/TanStack Query, Zustand, or Context for state, or when fixing hydration mismatches from localStorage.
State Management
Priority: P2 (MEDIUM)
Decision Guide
- Shareable/persistent? Use URL state (
useSearchParams+useRouter). - Server data? Use SWR or TanStack Query. Never sync into
useState. - Complex client UI? Use Zustand (in
'use client'only) or Jotai. - Simple local? Use
useState. Colocate as close to consumer as possible.
URL-Driven State
Server State (SWR / TanStack Query)
Client State (Zustand)
Hydration Safety
Wrap localStorage reads in useEffect or mounted flag to avoid hydration mismatches. Manage optimistic updates with useOptimistic in Next.js 15+.
Legacy Redux (existing projects)
If project already uses redux@4 + createStore + redux-thunk + next-redux-wrapper:
- Use
useSelector/useDispatchhooks — never connect HOC. - Define typed
RootStateand typedAppDispatchfor all selectors and dispatch calls. - Avoid adding Zustand or TanStack Query on top of existing Redux codebase — migrate incrementally if needed.
- Migration path: Redux Toolkit (
@reduxjs/toolkit) → RTK Query → then consider TanStack Query.
See references/redux.md for typed selector and thunk patterns.
Library Patterns
Anti-Patterns
- No global store for simple state: Use
useStateor URL params; avoid Zustand for basic UI. - No large objects in state: Decompose into granular primitives to prevent extra re-renders.
- No
useEffectfor data fetching: Use SWR or TanStack Query for server state. - No server state in client stores: Fetch in RSCs; client stores for UI-only state.
