react-components

Project rules for writing React components, including the component style, Chakra UI for layout, client-side navigation, page metadata, lazy-loaded pages, and Redux state access.

In plain words
What is it for?
Building React pages and components, setting page titles and descriptions, adding routes, managing shared state, and extracting reusable hooks or interface elements.
Why use it?
It keeps new React code consistent with the project's existing structure and avoids common implementation and maintenance problems.

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.

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-components 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

React Component Rules

  • Use arrow functions for all components. Never use the class keyword.
  • Use Chakra UI components (Box, Flex, Container, Button, etc.) for layout and styling.
  • Use React Router's Link or RouterLink for client-side navigation.
  • Pages must include <title> and <meta name="description"> using React 19 document metadata.
  • Use lazy loading (React.lazy) for page components in App.tsx.
  • Prefer useSelector and useDispatch from react-redux for Redux state access.
  • Avoid nested ternary operators. Use early returns or helper variables instead.
  • Don't duplicate code. Extract shared logic into hooks (src/client/hooks/) or UI components (src/client/ui/).
Changes

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.
