nuqs

A guide to managing typed state in URL query parameters with nuqs across React-based frameworks. Query parameters are the key-value settings after a URL's question mark.

In plain words
What is it for?
Use it when adding or reviewing nuqs state in Next.js, React Router, TanStack Router, Remix, or plain React, including server integration and testing.
Why use it?
It helps keep filters, searches, sorting, and pagination shareable, reloadable, and consistent between the browser and the application.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

nuqs 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 yesterday.

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.

Community nuqs Best Practices for Next.js & React

Comprehensive guide for type-safe URL query state management with nuqs across Next.js, React Router, TanStack Router, Remix, and plain React. Covers nuqs v2.5–v2.9 features. Contains 39 rules across 8 categories, prioritized by impact to guide code generation, refactoring, and code review.

When to Apply

Reference these guidelines when:

  • Implementing URL-based state with nuqs
  • Setting up nuqs in a Next.js or React Router project
  • Configuring parsers for URL parameters
  • Integrating URL state with Server Components
  • Optimizing URL update performance (limitUrlUpdates, key isolation)
  • Sharing parser definitions with tRPC / TanStack Router / forms via Standard Schema
  • Debugging nuqs-related issues

Rule Categories by Priority

Priority Category Impact Prefix
1 Parser Configuration CRITICAL parser-
2 Adapter & Setup CRITICAL setup-
3 State Management HIGH state-
4 Server Integration HIGH server-
5 Performance Optimization MEDIUM perf-
6 History & Navigation MEDIUM history-
7 Debugging & Testing LOW-MEDIUM debug-
8 Advanced Patterns LOW advanced-

What ships with it

44 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

nuqs is a skill published in the GitHub repository pproenca/dot-skills (200 stars, last pushed 16d ago), licensed MIT. It adds 90 tokens to every session and 1,589 once invoked, about $0.0005 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 2026-08-30.
