devtools

devtools is a skill for Claude Code, Codex from TanStack/table. It costs 48 tokens per session (625 once invoked), scanned A, original, MIT.

A guide to connecting Angular TanStack Table instances to TanStack Table Devtools, a development interface for inspecting tables while you build an app. Angular is a web framework.

In plain words
What is it for?
Use it to register tables for debugging, enable or disable registration reactively, and configure the required application-level devtools host.
Why use it?
It makes table state and configuration easier to inspect, while avoiding registration errors caused by using the devtools outside Angular's managed setup.

About the project

TanStack Table is a headless table library: it supplies table and datagrid logic while leaving the markup, styling, and components to the application. Developers use it with JavaScript and TypeScript frameworks to build customizable tables with features such as sorting, filtering, grouping, aggregation, and row selection. Its catalogue skills provide version-matched guidance for coding agents working with the library.

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

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 19d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill builds on @tanstack/table-core#core and @tanstack/table-devtools#devtools.

Setup

import { Component } from '@angular/core'
import { injectTable, tableFeatures } from '@tanstack/angular-table'
import { injectTanStackTableDevtools } from '@tanstack/angular-table-devtools'

const features = tableFeatures({})
const columns = [{ accessorKey: 'id' }]
const data: Array<{ id: string }> = []

@Component({ selector: 'users-table', template: 'Users table registered' })
export class UsersTable {
  readonly table = injectTable(() => ({
    key: 'users-table',
    features,
    columns,
    data,
  }))

  constructor() {
    injectTanStackTableDevtools(() => ({ table: this.table }))
  }
}

Provide the Angular TanStack Devtools host once at application configuration level as documented in docs/devtools.md.

Hooks and Components

The injector options function may return table: undefined or an enabled function to remove/disable registration reactively.

Common Mistakes

CRITICAL Injector called outside context

Wrong: call injectTanStackTableDevtools from an arbitrary callback after bootstrap.

Correct: call it in a component/service field initializer or constructor injection context.

The adapter uses Angular injection and effects for lifecycle cleanup.

Source: TanStack/table:packages/angular-table-devtools/src/injectTanStackTableDevtools.ts

HIGH Missing table key

Wrong: register an otherwise valid table without options.key.

Correct: assign a stable unique key before injection registration.

Core registration logs an error and skips keyless targets.

Source: TanStack/table:packages/table-devtools/src/tableTarget.ts

MEDIUM isDevMode no-op misunderstood

Wrong: expect default Angular exports to render production Devtools.

Correct: keep standard setup development-only; use /production only when explicitly requested.

The package index switches exports using Angular isDevMode().

Source: TanStack/table:packages/angular-table-devtools/src/index.ts
