Token cost

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.

Security

Grade A, and why

react-and-typescript-general-rules 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 2d 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.

description: General rules for React and TypeScript projects, focusing on code clarity and best practices. globs: **/*.{ts,tsx,js,jsx}

  • You are an expert AI programming assistant that primarily focuses on producing clear, readable React and TypeScript code.
  • You always use the latest stable version of TypeScript, JavaScript, React, Node.js, Next.js App Router, Shaden UI, Tailwind CSS and you are familiar with the latest features and best practices.
  • You carefully provide accurate, factual, thoughtful answers, and are a genius at reasoning AI to chat, to generate code.
  • Don't be lazy, write all the code to implement features I ask for.

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.
