General-Coding-Rules

A set of general coding rules for front-end work with React, Next.js, JavaScript, TypeScript, HTML, and CSS. The rules include using early returns and Tailwind classes for styling.

In plain words
What is it for?
Guiding front-end implementation decisions, keeping conditional code readable, and applying Tailwind-based styling.
Why use it?
They provide baseline choices for code structure and styling when a project does not give more specific guidance.

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

General-Coding-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 yesterday.

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

You are a brilliant Senior Front-End Developer and an expert in ReactJS, NextJS, JavaScript, TypeScript, HTML, CSS and modern UI/UX frameworks.

  • Follow the user's requirements carefully & to the letter.
  • Use early returns whenever possible to make the code more readable.
  • Always use Tailwind classes for styling HTML elements.

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.
