# Uno Toolkit Command Extensions — Agent Skill ## Workflow > **Docs lookup:** call `uno_platform_docs_search(...)` first, then `uno_platform_docs_fetch(sourcePath="…")` using the `sourcePath` field from a result (a relative `.md` path; add the result's `anchor` for a section). Never pass a URL, a `.html` link, or a hand-built path. ### Step 1: Fetch the CommandExtensions Documentation ``` uno_platform_docs_search("Uno Toolkit CommandExtensions command TextBox enter ToggleSwitch ListView tap") ``` Primary documentation pages: - **CommandExtensions (Chefs)**: `external/uno.chefs/doc/toolkit/CommandExtensions.md` - **Command Extensions helper**: search for `CommandExtensions` in toolkit helpers Fetch the Chefs page: ``` uno_platform_docs_fetch(sourcePath="external/uno.chefs/doc/toolkit/CommandExtensions.md") ``` ### Step 2: For Reference Documentation ``` uno_platform_docs_search("Uno Toolkit CommandExtensions attached property Command CommandParameter") ``` ## Critical Rules - There is **no `CommandTrigger` attached property**. `utu:CommandExtensions.Command="{Binding ...}"` alone is sufficient — the trigger event is determined automatically by the control type (Enter on `TextBox`/`PasswordBox`, item click on `ListView`, toggle on `ToggleSwitch`, invocation on `NavigationView`, tap on any `UIElement`). Do not invent a separate trigger property. - `Command` on `ListView` requires `IsItemClickEnabled="True"` to fire. ## Key Principles (Stable) - `utu:CommandExtensions.Command="{Binding MyCommand}"` — attaches a command - `utu:CommandExtensions.CommandParameter` — optional parameter - Supported controls: TextBox (enter key), PasswordBox, ToggleSwitch, ListView, NavigationView, ItemsRepeater, any UIElement (tap) - XAML namespace: `xmlns:utu="using:Uno.Toolkit.UI"` ## Related Skills - [[uno-toolkit-input-extensions]] — Input field focus flow - [[uno-toolkit-itemsrepeater-extensions]] — ItemsRepeater selection
