react-router-declarative-mode

react-router-declarative-mode is a skill for Claude Code, Codex from remix-run/agent-skills. It costs 47 tokens per session (758 once invoked), scanned A, original, MIT.

Guidance for adding basic in-browser page navigation to React apps with React Router's declarative mode. It covers routes, links, and values read from the web address without built-in data loading or form actions.

In plain words
What is it for?
Use it to configure BrowserRouter, Routes, and Route; add Link or NavLink navigation; navigate in code; and read path parameters, search parameters, or the current location.
Why use it?
It removes the need to work out the basic routing setup and URL handling yourself.

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-router-declarative-mode 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 8d 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.

React Router Declarative Mode

Declarative mode is React Router's simplest mode using <BrowserRouter>, <Routes>, and <Route> for basic client-side routing without data loading features like loaders or actions.

When to Apply

  • Using <BrowserRouter> for routing
  • Configuring routes with <Routes> and <Route>
  • Navigating with <Link>, <NavLink>, or useNavigate
  • Reading URL params with useParams
  • Working with search params using useSearchParams
  • Accessing location with useLocation

References

Load the relevant reference for detailed guidance on the specific API/concept:

Reference Use When
references/routing.md Configuring routes, nested routes, dynamic params
references/navigation.md Links, NavLink active states, programmatic nav
references/url-values.md Reading params, search params, location

Critical Patterns

These are the most important patterns to follow. Load the relevant reference for full details.

Basic Route Setup

Configure routes with JSX using <Routes> and <Route>:

import { BrowserRouter, Routes, Route } from "react-router";

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="about" element={<About />} />
        <Route path="dashboard" element={<Dashboard />}>
          <Route index element={<DashboardHome />} />
          <Route path="settings" element={<Settings />} />
        </Route>
        <Route path="users/:userId" element={<User />} />
      </Routes>
    </BrowserRouter>
  );
}

NavLink Active States

Use NavLink for navigation with active styling:

import { NavLink } from "react-router";

function Nav() {
  return (
    <nav>
      <NavLink
        to="/"
        end
        className={({ isActive }) => (isActive ? "active" : "")}
      >
        Home
      </NavLink>
      <NavLink
        to="/dashboard"
        className={({ isActive }) => (isActive ? "active" : "")}
      >
        Dashboard
      </NavLink>
    </nav>
  );
}

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.
