Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00390 |
| Opus 5 | $0.00018 | $0.00195 |
| Sonnet 5 | $0.00007 | $0.00078 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
zustand-state-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Zustand State Management
Lightweight, scalable state management for React. No boilerplate, no providers, just stores.
Why Zustand?
| Feature | Redux Toolkit | Zustand | Jotai |
|---|---|---|---|
| Boilerplate | Medium | Minimal | Minimal |
| Bundle Size | ~12kb | ~1kb | ~2kb |
| Provider needed | Yes | No | Yes |
| DevTools | Built-in | Middleware | External |
| Learning curve | Steep | Easy | Easy |
Core Patterns
// Store creation
const useStore = create<State>((set, get) => ({
count: 0,
increment: () => set((s) => ({ count: s.count + 1 })),
// Async actions
fetchData: async () => {
const data = await api.fetch()
set({ data })
},
}))
// Usage in components
const count = useStore((s) => s.count) // Auto-memoized selector
Middleware Stack
| Middleware | Purpose |
|---|---|
persist |
localStorage/sessionStorage persistence |
devtools |
Redux DevTools integration |
immer |
Immutable updates with mutable syntax |
subscribeWithSelector |
Fine-grained subscriptions |
Anti-Patterns
| ❌ Don't | ✅ Do |
|---|---|
Select entire store useStore() |
Use selectors useStore(s => s.count) |
| Put server state in store | Use TanStack Query for server state |
| One mega store | Split into focused domain stores |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

zustand-state-management is a skill published in the GitHub repository hoangatg/ai-agent-toolkit (1 stars, last pushed 5mo ago), licensed MIT. It adds 37 tokens to every session and 390 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
