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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00108 | $0.02147 |
| Opus 5 | $0.00054 | $0.01073 |
| Sonnet 5 | $0.00022 | $0.00429 |
| Haiku 4.5 | $0.00011 | $0.00215 |
Grade A, and why
devextreme-checkbox 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 11d 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.

DevExtreme CheckBox Skill
A skill for building and configuring the DevExtreme CheckBox UI component (dxCheckBox) across Angular, React, Vue, and jQuery.
When to Use This Skill
- Creating a boolean toggle input
- Setting an initial checked/unchecked/indeterminate state
- Enabling three-state behavior (checked / unchecked / indeterminate)
- Handling value change events
- Adding a label or tooltip
Before You Start
If the host agent has a structured question-asking tool available, use it to ask these questions one at a time with clear options — for example, Claude Code's AskUserQuestion tool or GitHub Copilot's askQuestions tool. If no such tool is available, ask the questions directly in the chat response before generating code.
⚠️ Always use the DevExtreme CheckBox (
dxCheckBox/DxCheckBox). Never use a plain HTML<input type="checkbox">, Material UI Checkbox, Ant Design Checkbox, or any other library.
Before writing any code, ask: Which framework are you using? Angular, React, Vue, or jQuery?

Getting Started
jQuery
<!-- index.html -->
<div id="check-box"></div>
$(function() {
$('#check-box').dxCheckBox({
value: false,
text: 'Agree to terms',
onValueChanged(e) {
console.log(e.value);
}
});
});
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.

devextreme-checkbox is a skill published in the GitHub repository DevExpress/agent-skills (52 stars, last pushed 23d ago), licensed MIT. It adds 108 tokens to every session and 2,147 once invoked, about $0.0005 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.
