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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.01049 |
| Opus 5.5 | $0.00015 | $0.00420 |
| Sonnet 5.5 | $0.00007 | $0.00210 |
| Haiku 4.5 | $0.00004 | $0.00105 |
Grade A, and why
tanstack-router-best-practices 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 1mo 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.

TanStack Router Best Practices
Comprehensive guidelines for implementing TanStack Router patterns in React applications. These rules optimize type safety, data loading, navigation, and code organization.
When to Apply
- Setting up application routing
- Creating new routes and layouts
- Implementing search parameter handling
- Configuring data loaders
- Setting up code splitting
- Integrating with TanStack Query
- Refactoring navigation patterns
Rule Categories by Priority
| Priority | Category | Rules | Impact |
|---|---|---|---|
| CRITICAL | Type Safety | 4 rules | Prevents runtime errors and enables refactoring |
| CRITICAL | Route Organization | 5 rules | Ensures maintainable route structure |
| HIGH | Router Config | 1 rule | Global router defaults |
| HIGH | Data Loading | 6 rules | Optimizes data fetching and caching |
| HIGH | Search Params | 5 rules | Enables type-safe URL state |
| HIGH | Error Handling | 1 rule | Handles 404 and errors gracefully |
| MEDIUM | Navigation | 5 rules | Improves UX and accessibility |
| MEDIUM | Code Splitting | 3 rules | Reduces bundle size |
| MEDIUM | Preloading | 3 rules | Improves perceived performance |
| LOW | Route Context | 3 rules | Enables dependency injection |
Quick Reference
Type Safety (Prefix: ts-)
ts-register-router— Register router type for global inferencets-use-from-param— Usefromparameter for type narrowingts-route-context-typing— Type route context with createRootRouteWithContextts-query-options-loader— Use queryOptions in loaders for type inference
Router Config (Prefix: router-)
router-default-options— Configure router defaults (scrollRestoration, defaultErrorComponent, etc.)
Route Organization (Prefix: org-)
org-file-based-routing— Prefer file-based routing for conventionsorg-route-tree-structure— Follow hierarchical route tree patternsorg-pathless-layouts— Use pathless routes for shared layoutsorg-index-routes— Understand index vs layout routesorg-virtual-routes— Understand virtual file routes

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.

tanstack-router-best-practices is a skill published in the GitHub repository DeckardGer/tanstack-agent-skills (224 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 1,049 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
