openstatusHQ/data-table-filters is a React toolkit for building data tables with filters, sorting, scrolling, and reusable table components. It helps developers create filterable tables using shadcn/ui and TanStack Table. The catalogue add-ons provide table blocks, state adapters, cell renderers, query integration, and other parts of its workflow.
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 | $0.00067 | $0.01533 |
| Opus 5 | $0.00034 | $0.00766 |
| Sonnet 5 | $0.00013 | $0.00307 |
| Haiku 4.5 | $0.00007 | $0.00153 |
Grade A, and why
vercel-react-best-practices 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 5d 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
78% identical to vercel-react-best-practices — 12 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.

Vercel React Best Practices
Comprehensive performance optimization guide for React and Next.js applications, maintained by Vercel. Contains 57 rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.
When to Apply
Reference these guidelines when:
- Writing new React components or Next.js pages
- Implementing data fetching (client or server-side)
- Reviewing code for performance issues
- Refactoring existing React/Next.js code
- Optimizing bundle size or load times
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Eliminating Waterfalls | CRITICAL | async- |
| 2 | Bundle Size Optimization | CRITICAL | bundle- |
| 3 | Server-Side Performance | HIGH | server- |
| 4 | Client-Side Data Fetching | MEDIUM-HIGH | client- |
| 5 | Re-render Optimization | MEDIUM | rerender- |
| 6 | Rendering Performance | MEDIUM | rendering- |
| 7 | JavaScript Performance | LOW-MEDIUM | js- |
| 8 | Advanced Patterns | LOW | advanced- |
Quick Reference
1. Eliminating Waterfalls (CRITICAL)
async-defer-await- Move await into branches where actually usedasync-parallel- Use Promise.all() for independent operationsasync-dependencies- Use better-all for partial dependenciesasync-api-routes- Start promises early, await late in API routesasync-suspense-boundaries- Use Suspense to stream content
2. Bundle Size Optimization (CRITICAL)
bundle-barrel-imports- Import directly, avoid barrel filesbundle-dynamic-imports- Use next/dynamic for heavy componentsbundle-defer-third-party- Load analytics/logging after hydrationbundle-conditional- Load modules only when feature is activatedbundle-preload- Preload on hover/focus for perceived speed

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.
- 5d ago First seen · 139 lines · 67 tokens per session scan A e8841c6512b3
vercel-react-best-practices is a skill published in the GitHub repository openstatusHQ/data-table-filters (2,225 stars, last pushed yesterday), licensed MIT. It adds 67 tokens to every session and 1,533 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 78% identical to vercel-react-best-practices, differing in 12 lines, and is treated as a copy.
