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 | $0.00076 | $0.01535 |
| Opus 5.5 | $0.00030 | $0.00614 |
| Sonnet 5.5 | $0.00015 | $0.00307 |
| Haiku 4.5 | $0.00008 | $0.00153 |
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 1mo 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.
This is a copy
92% identical to nuqs — 23 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Community nuqs Best Practices for Next.js
Comprehensive guide for type-safe URL query state management with nuqs in Next.js applications. Contains 42 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 project
- Configuring parsers for URL parameters
- Integrating URL state with Server Components
- Optimizing URL update performance
- 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- |
Quick Reference
1. Parser Configuration (CRITICAL)
parser-use-typed-parsers- Use typed parsers for non-string valuesparser-with-default- Use withDefault for non-nullable stateparser-enum-validation- Use enum parsers for constrained valuesparser-array-format- Choose correct array parser formatparser-json-validation- Validate JSON parser inputparser-date-format- Select appropriate date parserparser-index-offset- Use parseAsIndex for 1-based URL displayparser-hex-colors- Use parseAsHex for color values
2. Adapter & Setup (CRITICAL)
setup-nuqs-adapter- Wrap app with NuqsAdaptersetup-use-client- Add 'use client' directive for hookssetup-import-server- Import server utilities from nuqs/serversetup-nextjs-version- Ensure compatible Next.js versionsetup-shared-parsers- Define shared parsers in dedicated file

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.
- 1mo ago First seen · 116 lines · 76 tokens per session scan A 291e1013819b
nuqs is a skill published in the GitHub repository Cratis/AI (4 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 1,535 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to nuqs, differing in 23 lines, and is treated as a copy.
