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 | $0.00175 | $0.02171 |
| Opus 5.5 | $0.00070 | $0.00868 |
| Sonnet 5.5 | $0.00035 | $0.00434 |
| Haiku 4.5 | $0.00017 | $0.00217 |
Grade A, and why
devexpress-xaf-controllers 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 10d 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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress XAF — Controllers & Actions
Controllers are the primary mechanism for adding custom features, UI interaction, and business logic to XAF applications. Actions are abstract UI elements (buttons, menus, dropdowns) that live inside controllers.
Prerequisites & Installation
NuGet Packages
Controllers and Actions are part of the core XAF framework — no additional module registration is required.
| Package | Purpose |
|---|---|
DevExpress.ExpressApp |
ViewController, WindowController, ObjectViewController<,>, Frame, View, ObjectSpace |
DevExpress.ExpressApp.Actions |
SimpleAction, SingleChoiceAction, PopupWindowShowAction, ParametrizedAction |
Both packages are included in every XAF project by default.
Where to Place Controllers
| Location | Scope |
|---|---|
MySolution.Module\Controllers\ |
Platform-agnostic — runs in both Blazor and WinForms |
MySolution.Blazor.Server\Controllers\ |
Blazor-only controllers |
MySolution.Win\Controllers\ |
WinForms-only controllers |
Controllers are discovered automatically — no manual registration in Module.cs is needed.
Using Statements
using DevExpress.ExpressApp; // ViewController, ObjectViewController, WindowController
using DevExpress.ExpressApp.Actions; // SimpleAction, SingleChoiceAction, PopupWindowShowAction
using DevExpress.Persistent.Base; // PredefinedCategory, ImageName
Controller Types
Refer to references/controller-types.md
When you need to:
- Create a non-generic
ViewControllerthat activates for all views - Create a
ViewController<ListView>orViewController<DetailView>scoped to a view type - Create an
ObjectViewController<ViewType, ObjectType>with typed access to the current object - Create a
WindowControllerfor UI features not tied to specific views
Controller Lifecycle
The lifecycle of a ViewController follows this order:
What ships with it
5 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.

devexpress-xaf-controllers is a skill published in the GitHub repository DevExpress/agent-skills (66 stars, last pushed 11d ago), licensed MIT. It adds 175 tokens to every session and 2,171 once invoked, about $0.0007 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.
