Covers the full SOLID module structure (modules/cores/lib/router/, feature modules with interfaces//queries//components/), migration from React Router (useParams()→Route.useParams(), loader→loader option), and error boundaries/404 handling. Does not cover state management (react-state) or forms (react-forms) — those are separate skills; for Next.js routing use the App Router (nextjs-16), not this skill.

TanStack Router

100% type-safe router for React with file-based routing, loaders, search params validation, and deep TanStack Query integration.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing routes and navigation patterns
2. fuse-ai-pilot:research-expert - Verify latest TanStack Router docs via Context7/Exa
3. mcp__context7__query-docs - Check file-based routing and type-safe patterns

After implementation, run fuse-ai-pilot:sniper for validation.
