+name: winmd-api-search
+description: 'Find and explore Windows desktop APIs. Use when building features that need platform capabilities — camera, file access, notifications, UI controls, AI/ML, sensors, networking, etc. Discovers the right API for a task and retrieves full type details (methods, properties, events, enumeration values).'
+---
+
+# WinMD API Search
+
+This skill helps you find the right Windows API for any capability and get its full details. It searches a local cache of all WinMD metadata from:
+
+- **Windows Platform SDK** — all `Windows.*` WinRT APIs (always available, no restore needed)
+- **WinAppSDK / WinUI** — bundled as a baseline in the cache generator (always available, no restore needed)
+- **NuGet packages** — any additional packages in restored projects that contain `.winmd` files
+- **Project-output WinMD** — class libraries (C++/WinRT, C#) that produce `.winmd` as build output
+
+Even on a fresh clone with no restore or build, you still get full Platform SDK + WinAppSDK coverage.
+
+## When to Use
+
+- User wants to build a feature and you need to find which API provides that capability
+- User asks "how do I do X?" where X involves a platform feature (camera, files, notifications, sensors, AI, etc.)
+- You need the exact methods, properties, events, or enumeration values of a type before writing code
+- You're unsure which control, class, or interface to use for a UI or system task
+
+## How to Use
+
+Pick the path that matches the situation:
+
+---
+
+### Discover — "I don't know which API to use"
+
+The user describes a capability in their own words. You need to find the right API.
+
+**1. Translate user language → search keywords**
+
+Map the user's daily language to programming terms. Try multiple variations:
+
+| User says | Search keywords to try (in order) |
+|-----------|-----------------------------------|
+| "take a picture" | `camera`, `capture`, `photo`, `MediaCapture` |
+| "load from disk" | `file open`, `picker`, `FileOpen`, `StorageFile` |
+| "describe what's in it" | `image description`, `Vision`, `Recognition` |
+| "show a popup" | `dialog`, `flyout`, `popup`, `ContentDialog` |
+| "drag and drop" | `drag`, `drop`, `DragDrop` |
+| "save settings" | `settings`, `ApplicationData`, `LocalSettings` |
+
+Start with simple everyday words. If results are weak or irrelevant, try the more technical variation.
+
+**2. Run searches**
+
+```powershell
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action search -Query "<keyword>"
+```
+
+This returns ranked namespaces with top matching types and the **JSON file path**.
+
+**3. Read the JSON to choose the right API**
+
+Use `read_file` on the file path(s) from the top results. The JSON has all types in that namespace — full members, signatures, parameters, return types, enumeration values.
+
+Read and decide which types and members fit the user's requirement.
+
+**4. Use the API knowledge to answer or write code**
+
+---
+
+### Lookup — "I know the API, show me the details"
+
+You already know (or suspect) the type or namespace name. Go direct:
+
+```powershell
+# Get all members of a known type
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action members -TypeName "Microsoft.UI.Xaml.Controls.NavigationView"
+
+# Get enum values
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action enums -TypeName "Microsoft.UI.Xaml.Visibility"
+
+# List all types in a namespace
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action types -Namespace "Microsoft.UI.Xaml.Controls"
+
+# Browse namespaces
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action namespaces -Filter "Microsoft.UI"
+```
+
+If you need full detail beyond what `-Action members` shows, use `-Action search` to get the JSON file path, then `read_file` the JSON directly.
+
+---
+
+### Other Commands
+
+```powershell
+# List cached projects
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action projects
+
+# Show stats
+.\.github\skills\winmd-api-search\scripts\Invoke-WinMdQuery.ps1 -Action stats
+```
+
+> If only one project is cached, `-Project` is auto-selected.
+> If multiple projects exist, add `-Project <name>`.
+
+## Search Scoring
+
+The search ranks type names against your query:
+
+| Score | Match type | Example |
+|-------|-----------|---------|
+| 100 | Exact name | `Button` → `Button` |
+| 80 | Starts with | `Navigation` → `NavigationView` |
+| 60 | Contains | `Dialog` → `ContentDialog` |
+| 50 | PascalCase initials | `ASB` → `AutoSuggestBox` |
+| 40 | Multi-keyword AND | `navigation item` → `NavigationViewItem` |
+| 20 | Fuzzy character match | `NavVw` → `NavigationView` |
+
+Results are grouped by namespace. Higher-scored namespaces appear first.
+
+## Cache Setup
+
+If the cache doesn't exist, generate it:
+
+```powershell
+# Single project
+.\.\.github\skills\winmd-api-search\scripts\Update-WinMdCache.ps1 -ProjectDir <project-folder>
+
+# All projects in the repo
+.\.\.github\skills\winmd-api-search\scripts\Update-WinMdCache.ps1
+```
+
+Requires:
+- **.NET SDK 8.0 or later** — auto-detects the highest installed SDK (>= 8). Install from [dotnet.microsoft.com](https://dotnet.microsoft.com/download) if not available.
+
+No project restore or build is needed for baseline coverage (Platform SDK + WinAppSDK). For additional NuGet packages, the project needs `dotnet restore` (which generates `project.assets.json`) or a `packages.config` file.
+
+Cache is stored at `Generated Files\winmd-cache\`, deduplicated per-package+version.
+
+### What gets indexed
+
+| Source | When available |
+|--------|----------------|
+| Windows Platform SDK | Always (reads from local SDK install) |
+| WinAppSDK (latest) | Always (bundled as baseline in cache generator) |
+| Project NuGet packages | After `dotnet restore` or with `packages.config` |
+| Project-output `.winmd` | After project build (class libraries that produce WinMD) |
+
+> **Note:** This cache directory should be in `.gitignore` — it's generated, not source.
+
+## Troubleshooting
+
+| Issue | Fix |
+|-------|-----|
+| "Cache not found" | Run `Update-WinMdCache.ps1` |
+| "Multiple projects cached" | Add `-Project <name>` |
+| "Namespace not found" | Use `-Action namespaces` to list available ones |
+| "Type not found" | Use fully qualified name (e.g., `Microsoft.UI.Xaml.Controls.Button`) |
+| Stale after NuGet update | Re-run `Update-WinMdCache.ps1` |
+| Cache in git history | Add `Generated Files/` to `.gitignore` |

+<#
+.SYNOPSIS
+    Generate or refresh the WinMD cache for the Agent Skill.
+
+.DESCRIPTION
+    Builds and runs the standalone cache generator to export cached JSON files
+    from all WinMD metadata found in project NuGet packages and Windows SDK.
+
+    The cache is per-package+version: if two projects reference the same
+    package at the same version, the WinMD data is parsed once and shared.
+
+    Supports single project or recursive scan of an entire repo.
+
+.PARAMETER ProjectDir
+    Path to a project directory (contains .csproj/.vcxproj), or a project file itself.
+    Defaults to scanning the workspace root.
+
+.PARAMETER Scan
+    Recursively discover all .csproj/.vcxproj files under ProjectDir.
+
+.PARAMETER OutputDir
+    Path to the cache output directory. Defaults to "Generated Files\winmd-cache".
+
+.EXAMPLE
+    .\Update-WinMdCache.ps1
+    .\Update-WinMdCache.ps1 -ProjectDir BlankWInUI
+    .\Update-WinMdCache.ps1 -Scan -ProjectDir .

 developers won't have to do anything. The toolkit will just do the right thing
 for them.
 
+## Addenda IV: Dock bands
+
+The "dock" is another way to surface commands to the user. This is a
+toolbar-like window that can be docked to the side of the screen, or floated as
+its own window. It enables another surface for extensions to display real-time
+information and shortcuts to users.
+
+Bands are powered by the same interfaces as DevPal itself. Extensions can provide
+bands via the new `DockBand` property on `ICommandProvider3`.
+
+```csharp
+interface ICommandProvider3 requires ICommandProvider2
+{
+    ICommandItem[] GetDockBands();
+};
+```
+
+A **Dock Band** is one "strip of items" in the dock. Each band can have multiple
+items. This allows an extension to create a strip of buttons that should all be
+treated as a single unit. For example, a media player band will want probably
+four items:
+* one for the previous track
+* one for play/pause
+* one for next track
+* and one to display the album art and track title
+
+`GetDockBands` returns an array of `ICommandItem`s. Each `ICommandItem`
+represents one band in the dock. These represent all of the bands that an
+extension would allow the user to add to their dock. 
+
+All of the `ICommandItem`s returned from `GetDockBands` **must** have a
+`Command` with a non-empty `Id` set. If the `Id` is null or empty, DevPal will
+ignore that band.
+
+Bands are not automatically added to the dock. Instead, the user must choose
+which bands they want to add. This is done via the DevPal settings page.
+Furthermore, bands are not displayed in the list of commands in DevPal itself.
+This allows extension authors to create objects that are only intended for the
+dock, without cluttering up the main DevPal UI, and vice versa.
+
+DevPal will then create UI in the dock for each band the user has chosen to add.
+What that looks like will depend on the `Command` in the `ICommandItem`:
+* A `IInvokableCommand` will be rendered as a single button. Think "the
+  time/date" button on the taskbar, that opens the notification center.
+* A `IListPage` will be rendered as a strip of buttons, one for each `IListItem`
+  in the list. Think "media controls" for a music player. 
+* A `IContentPage` will be rendered as a single button. Clicking that button
+  will open a flyout with that content rendered in it. Think "weather" or "news"
+  flyouts.
+
+If the `Command` in the `IListItem`s of a band are pages, then clicking those
+buttons will open DevPal to that page, as if it were a flyout from the dock.
+
+The `.Title` property of the top-level `ICommandItem` representing the band will
+be used as the name of the band in the settings. So a media player band might
+want to set the `Title` to "Contoso Music Player", even if the individual
+buttons in the band don't show that title.
+
+Users may also "pin" a top-level command from DevPal into the dock. DevPal will
+take care of creating a new band (owned by devpal) with that command in it. This
+allows users to add quick shortcuts to their favorite commands in the dock.
+Think: pinning an app, or pinning a particular GitHub query. 
+
+Bands are added via ID. An extension may choose to have a TopLevelCommand and a
+DockBand with the same `Id`. In this case, if the user pins the TopLevelCommand
+to the dock, DevPal will pin the band from `GetDockBands`, rather than creating
+a simple pinned command. This allows extension authors to seamlessly have a
+top-level command present a palette-specific experience, while also having a
+dock-specific experience. In our ongoing media player example, the top-level
+command might open DevPal to a full-featured music control page, while the dock
+band has simpler buttons on it (without a title/subtitle).
+
+Users may choose to have:
+* the orientation of the dock: vertical or horizontal
+* the size of the dock
+* which bands are shown in the dock
+* whether the "labels" (read: `Title` & `Subtitle`) of individual bands are
+  shown or hidden.
+  - Dock bands will still display the `Title` & `Subtitle` of each item in the
+    band as the tooltip on those items, even when the "labels" are hidden. 
+

 This is a diagram attempting to show the relationships between the various types we've defined for the SDK. Some elements are omitted for clarity. (Notably, `IconData` and `IPropChanged`, which are used in many places.)
