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 | $0.00188 | $0.03901 |
| Opus 5 | $0.00094 | $0.01951 |
| Sonnet 5 | $0.00038 | $0.00780 |
| Haiku 4.5 | $0.00019 | $0.00390 |
Grade A, and why
devexpress-winforms-accordion 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.
How it starts
The opening of the file, as written. The whole thing — 342 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress WinForms Accordion Control
AccordionControl is a side-navigation control that renders a hierarchical, expandable menu of groups and items. It is the recommended navigation control for new WinForms applications — more flexible than NavBarControl, and capable of serving as a full Hamburger Menu when ViewType = HamburgerMenu.
Groups (ElementStyle.Group) are expandable containers. Items (ElementStyle.Item) are clickable leaves that can optionally embed arbitrary WinForms controls inside an expandable content container. The hierarchy is unlimited in depth.
The control lives in the DevExpress.XtraBars.Navigation namespace and ships with the DevExpress.Win.Navigation NuGet package.
When to Use This Skill
- Setting up a side navigation menu in a WinForms application
- Adding groups, items, and content containers to an
AccordionControl - Generating menu items programmatically from data (lists, database queries, configuration)
- Switching the control to Hamburger Menu style and configuring display modes
- Customizing item headers, icons, appearance, and HTML-CSS templates
- Enabling search / filter functionality in the navigation menu
- Choosing between
AccordionControl,NavBarControl, and Hamburger Menu style - Integrating with
NavigationFrame,RibbonForm, orFluentDesignForm
Prerequisites & Installation
NuGet Package
DevExpress.Win.Navigation
Install-Package DevExpress.Win.Navigation
Required Namespace Imports
using DevExpress.XtraBars.Navigation;
using DevExpress.XtraEditors; // XtraForm
using DevExpress.XtraBars.Ribbon; // RibbonForm (optional)
Host Form
Always host AccordionControl on XtraForm (or RibbonForm / FluentDesignForm) — not on plain Form — to get correct skin-aware rendering.
Before You Start — Ask the Developer
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.
What ships with it
8 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.
