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 | $0.00216 | $0.04181 |
| Opus 5 | $0.00108 | $0.02090 |
| Sonnet 5 | $0.00043 | $0.00836 |
| Haiku 4.5 | $0.00022 | $0.00418 |
Grade A, and why
devexpress-winforms-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 12d 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 — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress WinForms Tab Control
XtraTabControl is a container that organizes other controls into pages. Each page is an XtraTabPage with a clickable header; the active page fills the control's body. Use it to build a tabbed UI in a local area of a form — a settings dialog, a multi-section editor, a property pane.
Pages live in the XtraTabControl.TabPages collection. The active page is XtraTabControl.SelectedTabPage. The control lives in the DevExpress.XtraTab namespace and ships with the DevExpress.Win.Navigation NuGet package.
Use Cases and Alternatives:
XtraTabControlis for organizing controls into pages in a fixed, local area — users cannot undock or rearrange pages. If you need a true MDI / document interface (floating, draggable, on-demand-loaded documents), use the Application UI Manager / DocumentManager or the simpler XtraTabbedMdiManager instead. For a browser-like form with page headers in the title bar, see Tabbed Form.
When to Use This Skill
- Adding a tabbed page UI to a form (settings, multi-section editor, property pane)
- Adding, removing, or reordering
XtraTabPagepages in code or the designer - Placing controls onto tab pages
- Positioning / orienting page headers (top, bottom, left, right; horizontal or vertical text)
- Wrapping headers into multiple rows when they don't fit (
MultiLine) - Showing Prev / Next / Close buttons in the header panel, or per-page Close buttons
- Responding to page selection (
SelectedPageChanged/SelectedPageChanging) or close (CloseButtonClick) events - Hiding headers and implementing wizard-style custom page navigation
- Adding icons or custom buttons to page headers

What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
