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 | $0.00022 | $0.01693 |
| Opus 5 | $0.00011 | $0.00847 |
| Sonnet 5 | $0.00004 | $0.00339 |
| Haiku 4.5 | $0.00002 | $0.00169 |
Grade A, and why
tanstack-devtools 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.
This is a copy
100% identical to tanstack-devtools — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Overview
TanStack Devtools provides a unified debugging interface that consolidates devtools for TanStack Query, Router, and other libraries into a single panel. It features a framework-agnostic plugin architecture, real-time state inspection, and support for custom plugins. Built with Solid.js for lightweight performance.

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.
