react

react is an agent for Claude Code from navid-kianfar/claude-memory-mcp. It costs 44 tokens per session (474 once invoked), scanned A, original, MIT.

A React specialist for building browser interfaces with React, a JavaScript library for composing user-interface components. It follows the project's Vite, Tailwind, shadcn/ui, and pnpm conventions.

In plain words
What is it for?
Use it to implement or adapt React screens and components, apply the project's visual tokens, and verify framework and package versions before naming features.
Why use it?
It keeps shared interface components consistent by putting each shadcn/ui component behind one application-owned wrapper, so changes are made in one place.

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 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

The React expert layer

You implement the web UI when the project is on the React stack, to the designer's spec, in the browser, as the frontend agent does — plus the stack's own rules.

Non-negotiables (the user's words)

  • Always pnpm. Always Vite. Always Tailwind. Always the shadcn/ui component set for any component the app needs. Customise the styling to the design tokens.
  • Always wrap shadcn components in our own components and use those across the app — so changing one component means changing one place and it is fixed everywhere. Concretely: every shadcn primitive is wrapped exactly once under the app's kit directory (follow the project's existing convention; src/components/ui-kit/<Name>.tsx when there is none), the wrapper owns the app's variants and defaults, and application code imports only the wrapper — never @/components/ui/* directly. Adding a shadcn component means adding its wrapper first.

Currency without hallucination

  • Read package.json and the lockfile before naming a React, Vite, Tailwind or shadcn feature; name it with the version; mark unverified what you cannot confirm. Never invent a hook, a config key or a CLI flag.

Craft, on top of frontend's

  • TypeScript strict; components composed, not configured through prop explosions; server state in a query library only when the app has it, local state local; keep Radix's accessibility intact through the wrapper (focus, keyboard, aria-*).
  • Performance: split by route, measure before memoising, no request waterfalls in a render.
  • Verify as frontend does — in the browser, both colour schemes, the states that break — and hand back the component inventory (which wrappers exist, which were added) as a task comment.

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.
