Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.08707 | $0.08707 |
| Opus 5.5 | $0.03483 | $0.03483 |
| Sonnet 5.5 | $0.01741 | $0.01741 |
| Haiku 4.5 | $0.00871 | $0.00871 |
Grade A, and why
tanstack-react-router_setup-and-architecture 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 2mo 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.

Overview
TanStack Router is a router for building React and Solid applications. Some of its features include:
- 100% inferred TypeScript support
- Typesafe navigation
- Nested Routing and layout routes (with pathless layouts)
- Built-in Route Loaders w/ SWR Caching
- Designed for client-side data caches (TanStack Query, SWR, etc.)
- Automatic route prefetching
- Asynchronous route elements and error boundaries
- File-based Route Generation
- Typesafe JSON-first Search Params state management APIs
- Path and Search Parameter Schema Validation
- Search Param Navigation APIs
- Custom Search Param parser/serializer support
- Search param middleware
- Route matching/loading middleware

"A Fork in the Route"
Using a router to build applications is widely regarded as a must-have and is usually one of the first choices you’ll make in your tech stack.
So, why should you choose TanStack Router over another router?
To answer this question, we need to look at the other options in the space. There are many if you look hard enough, but in my experience, only a couple are worth exploring seriously:
- Next.js - Widely regarded as the de facto framework for starting a new React project, it’s laser focused on performance, workflow, and bleeding edge technology. Its APIs and abstractions are powerful, but can sometimes come across as non-standard. Its extremely fast growth and adoption in the industry has resulted in a featured packed experience, but at the expense of feeling overwhelming and sometimes bloated.
- Remix / React Router - A full-stack framework based on the historically successful React Router offers a similarly powerful developer and user experience, with APIs and vision based firmly on web standards like Request/Response and a focus on running anywhere JS can run. Many of its APIs and abstractions are wonderfully designed and were inspiration for more than a few TanStack Router APIs. That said, its rigid design, bolted-on type safety and sometimes strict over-adherence to platform APIs can leave some developers wanting more.
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.
