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 | $0.00026 | $0.00766 |
| Opus 5 | $0.00013 | $0.00383 |
| Sonnet 5 | $0.00005 | $0.00153 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
react-skills 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 10d 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.

React Skills for LlamaFarm Designer
Best practices and patterns for React 18 development in the Designer subsystem.
Tech Stack
- React 18.2 with StrictMode
- TypeScript 5.2+ for type safety
- TanStack Query v5 for server state management
- React Router v7 for client-side routing
- TailwindCSS with
tailwind-mergeandclsxfor styling - Radix UI primitives for accessible components
- Vite for build tooling
- Vitest + React Testing Library for testing

Core Patterns
Component Composition
- Use composition over inheritance
- Prefer small, focused components
- Use
forwardReffor components that wrap DOM elements - Apply
displayNameto forwardRef components for DevTools
State Management
- Local UI state:
useState,useReducer - Server state: TanStack Query (
useQuery,useMutation) - Shared UI state: React Context with custom hooks
- Form state: Controlled components with validation
Hooks
- Follow Rules of Hooks (top-level, consistent order)
- Create custom hooks for reusable logic
- Use query key factories for TanStack Query
- Memoize expensive computations with
useMemo - Stabilize callbacks with
useCallback
Styling
- Use
cn()fromlib/utilsto merge Tailwind classes - Use
cva(class-variance-authority) for component variants - Follow dark mode conventions with
dark:prefix

What ships with it
5 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.
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.

react-skills is a skill published in the GitHub repository llama-farm/llamafarm (838 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 26 tokens to every session and 766 once invoked, about $0.0001 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.
