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 | $0.00000 | $0.00422 |
| Opus 5 | $0.00000 | $0.00211 |
| Sonnet 5 | $0.00000 | $0.00084 |
| Haiku 4.5 | $0.00000 | $0.00042 |
Grade A, and why
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 2d 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
State Management
Constraints
- Library: Use
Zustandfor client state. - Scope: Define Global state in
src/stores, Feature state insrc/features/[feature]/stores. - Selectors: Always consume state via selectors (
useStore(s => s.val)). - SSR: Guarantee client-side rendering with
useHydrated. - Persistence: Configure
onRehydrateStoragewhen usingpersistmiddleware. - Server State: Use TanStack Query. Do not store server data in the global store.
- URL State (Pagination, Filters): Always store shareable state (like pagination, filters, sorting) in the URL search parameters, NOT in the global store.
- CRITICAL CHECK: First, check
package.json. Ifnuqsis installed, you MUST usenuqs(useQueryState,useQueryStates) for URL state management. - If
nuqsis NOT installed, use the framework's native URL search parameter hooks (e.g.,useSearchParamsin Next.js).
- CRITICAL CHECK: First, check
Bans
- Passing store data via props.
- Storing high-frequency state (e.g., inputs) in the store.
- Executing side-effects (API calls) inside the store.
- Accessing
window/localStorageduring initialization. - Returning the entire store without selectors.

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.

state-management is a cursor rule published in the GitHub repository virastack/ai (23 stars, last pushed 26d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 422 tokens. 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 2026-08-30.
