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 | $0.00214 | $0.04701 |
| Opus 5.5 | $0.00086 | $0.01880 |
| Sonnet 5.5 | $0.00043 | $0.00940 |
| Haiku 4.5 | $0.00021 | $0.00470 |
Grade A, and why
devexpress-wpf-tab-control 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 3d 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 — 378 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress WPF Tab Control
DXTabControl is a tabbed navigation control: a header panel with selectable headers across the top (or side), and a content area that shows the active page. Headers can overflow into multiple lines, scroll, or shrink (one of three views); tabs can carry icons, custom colors, close buttons, and drag-drop reordering. Tabs can be defined explicitly as DXTabItem children, populated from an IList, or generated from a data collection via ItemsSource + templates.
Window hosting: For proper visual integration (themed title bar, ContentHeader/Footer aligning with the title bar, control box buttons in the tab bar), the host window should be
dx:ThemedWindow, not a plainWindow. UseThemedWindoweven when you don't otherwise need its features.
This skill covers project setup (with the ThemedWindow requirement), tab definition (XAML / Items / ItemsSource), the three layout views, and appearance customization.
When to Use This Skill
Use this skill when you need to:
- Add a tabbed page UI to a window
- Generate tabs dynamically from a view-model collection (
ItemsSource) - Allow users to close (
AllowHide) and reorder tabs - Pick a view (MultiLine / Scroll / Stretch) for header overflow behavior
- Color or theme individual tabs (
AccentColor,BorderColor) - Add custom content to the tab bar (left/right control box, content header/footer)
Prerequisites & Installation
NuGet Packages
| Package | Provides |
|---|---|
DevExpress.Wpf.Core |
DXTabControl, DXTabItem, ThemedWindow |
dotnet add package DevExpress.Wpf.Core
A valid DevExpress license is required. All DevExpress packages in a project must share the same version.
Host Window — Use ThemedWindow, Not Window
The host window should be dx:ThemedWindow. DXTabControl integrates with ThemedWindow for:
- Themed title bar continuous with the tab header area
ControlBoxLeftTemplate/ControlBoxRightTemplaterendering correctly in the title bar- Tab drag-out creating a properly themed pop-out window
- Theming hooks via
IThemedWindowSupport

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.

devexpress-wpf-tab-control is a skill published in the GitHub repository DevExpress/agent-skills (66 stars, last pushed 4d ago), licensed MIT. It adds 214 tokens to every session and 4,701 once invoked, about $0.0009 per session on Opus 5.5. 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 2026-10-20.
