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 | $0.00209 | $0.00209 |
| Opus 5.5 | $0.00084 | $0.00084 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
vibe-coding-ai-rules react.instructions.md 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 2mo 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
React Patterns
Component Structure
- Functional components only (no class components)
- Server Components by default; Client Components ('use client') only when needed
- Extract business logic into custom hooks or service layer
- Max 200 lines per component file
State Management
- Local state: useState/useReducer
- Server state: React Query / SWR
- Global state: Zustand (or specified alternative)
- URL state: nuqs or searchParams
Performance
- Use React.memo() only with measured performance issues
- Implement proper key props for lists
- Lazy load heavy components with React.lazy() + Suspense
- Use optimistic updates for better UX
Error Handling
- Implement Error Boundaries for fault isolation
- Use proper loading/error/empty states for async data
- Never swallow errors silently
Accessibility
- All interactive elements need keyboard support
- Use semantic HTML elements
- Include proper ARIA labels where needed
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.
