tanstack-devtools

tanstack-devtools is a skill for Claude Code, Codex from louisbrulenaudet/monorepo-template. It costs 22 tokens per session (1,693 once invoked), scanned A, a copy of tanstack-devtools, Apache-2.0.

A shared debugging panel for TanStack libraries, including Query and Router, that lets you inspect application state while the app runs. It can also accept additional debugging plugins.

In plain words
What is it for?
Use it to inspect TanStack Query data and TanStack Router behavior in a React or Solid application, and to add custom debugging panels.
Why use it?
It puts several library-specific debugging views in one place, so you do not have to switch between separate tools when investigating an application.

Token cost

What it costs to keep this loaded

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.

Security

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.

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.

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.
