Trigger Keywords

Activate this skill when the user mentions any of:

Meta-Framework: TanStack Start, TanStack Start Solid, Server Functions, createServerFn

Libraries: @tanstack/solid-query, @tanstack/solid-router, @tanstack/solid-table, @tanstack/solid-form

Concepts: createQuery, createMutation, createRouter, createSolidTable, createForm </trigger_keywords>

⛔ Forbidden Patterns

1. NO Destructuring Query Results: const { data } = createQuery(...) breaks reactivity. Always use query.data.
2. NO Static Options Objects: Passing a static object to createQuery prevents updates when dependencies change. Pass a function: createQuery(() => ({ ... })).
3. NO React Patterns: Do not use useQuery or useEffect. Use createQuery and createEffect.
4. NO Direct Prop Access in Options: If using props in options, access them inside the getter function: () => props.id.
5. NO Manual Refetching Loop: Do not use setInterval to refetch. Use refetchInterval in Query options.

🤖 Agent Tool Strategy

1. Reactivity Check: Verify that all options objects passed to TanStack creators are wrapped in functions (e.g., () => ({ ... })) if they depend on signals/props.
2. Server Functions: For TanStack Start, use createServerFn for backend logic instead of API routes where possible.
3. Type Safety: Prioritize the type-safe routing features of TanStack Router (file-based routing, createFileRoute).

Quick Reference (30 seconds)

TanStack Solid Specialist - Type-safe, Headless, Reactive.

Core Philosophy:

• Solid Adapter: All libraries use Solid's fine-grained reactivity.
• Getters are King: Options must be getters to track dependencies.
• Type Safety: End-to-end type safety from router to server functions.

Key Libraries:

• Start: Full-stack meta-framework.
• Query: Async state management (createResource alternative).
• Router: Type-safe routing.
• Table: Headless data tables.
• Form: Headless form state management.
