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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00282 |
| Opus 5 | $0.00000 | $0.00141 |
| Sonnet 5 | $0.00000 | $0.00056 |
| Haiku 4.5 | $0.00000 | $0.00028 |
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 9d 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
Vercel React Best Practices
Build React and Next.js code that fits modern app-router, component, data-fetching, and deployment expectations.
Use When
- Editing React, Next.js, server components, client components, route handlers, or UI state.
- Reviewing frontend architecture, hydration issues, bundle size, streaming, caching, or server/client boundaries.
- Adding production-grade React features to an existing app.
Playbook
- Inspect the existing project conventions before adding patterns.
- Keep server-only code out of client components.
- Keep client components focused on interactivity, browser APIs, and local UI state.
- Prefer typed props and small components with clear ownership.
- Avoid unnecessary global state; use URL state, server data, or local state when simpler.
- Verify with TypeScript and the narrowest relevant UI/runtime check.
Guardrails
- Do not migrate routing, styling, or state libraries unless the user explicitly asks.
- Do not add dependencies for problems the app already solves.
- Do not enable this by default for every agent; enable it for React/Next.js implementation roles.
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.

vercel-react-best-practices is a skill published in the GitHub repository aaronnat23/disp8ch (100 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 282 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 2026-09-03.
