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 | $0.00115 | $0.04646 |
| Opus 5 | $0.00057 | $0.02323 |
| Sonnet 5 | $0.00023 | $0.00929 |
| Haiku 4.5 | $0.00012 | $0.00465 |
Grade A, and why
tanstack-start 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 526 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TanStack Start on Cloudflare
Build a complete full-stack app from nothing. Claude generates every file — no template clone, no scaffold command.
Stack: TanStack Start v1 (SSR, file-based routing, server functions via Nitro) on Cloudflare Workers; React 19 + Tailwind v4 + shadcn/ui; D1 + Drizzle; better-auth (Google OAuth + email/password).

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.
- 5d ago First seen · 526 lines · 115 tokens per session scan A 01e074ce5ff2
tanstack-start is a skill published in the GitHub repository jezweb/claude-skills (996 stars, last pushed 2mo ago), licensed MIT. It adds 115 tokens to every session and 4,646 once invoked, about $0.0006 per session on Opus 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.
