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

igniteui-react-customize-theme 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 2d 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.

The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ignite UI for React — Theming Skill

Prerequisites

  • A React project with igniteui-react installed
  • A theme CSS file imported in your entry point (see igniteui-react-components)
  • The Ignite UI Theming MCP server (igniteui-theming)

AGENT INSTRUCTION — MCP Server Setup (REQUIRED)

Before using any theming tools, you MUST verify the MCP server is available by calling detect_platform. If the tool is not available or the call fails, you MUST automatically configure it by following the setup process steps described below.

After writing the file, inform the user that the MCP server has been configured and they may need to reload the editor for the tools to activate. Start the MCP server and wait for that MCP server to start before continuing the theming related work. Do NOT skip this step or ask the user to do it manually.

Description

This skill teaches AI agents how to theme Ignite UI for React applications. One approach is supported:

  • CSS custom properties — works in any project without additional build tooling

The skill also covers component-level theming, layout controls (spacing, sizing, roundness), and how to use the Ignite UI Theming MCP server for AI-assisted code generation — all in a React application context.

Example Usage

  • "How do I change the primary color in my Ignite UI React app?"
  • "Apply a dark theme to my React app"
  • "Customize the grid header colors"
  • "How do I scope a theme to a specific section of my React app?"
  • "Set up Material Design theming for Ignite UI components"

Setting Up the Theming MCP Server

Full setup instructions for VS Code, Cursor, Claude Desktop, and JetBrains IDEs are in reference/MCP-SERVER.md. Read that file for editor-specific configuration steps and verification.

Changes

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.
