## Summary Adds an on-device **Phi Silica (Windows AI) paste provider** to Advanced Paste and richer per-action customization, plus the **package-identity plumbing** that lets the unpackaged Advanced Paste app use Windows AI APIs. > Note: this supersedes the earlier "self-contained MSIX package installed/registered by the > WiX installer" approach. Advanced Paste is **not** packaged or installed as a standalone > MSIX. It keeps shipping as the existing unpackaged, self-contained WinUI 3 executable in > `WinUI3Apps/` and acquires **package identity at runtime from the existing PowerToys sparse > package** — there are no installer or ESRP MSIX repack changes. ## Advanced Paste features - **New Phi Silica paste provider** (`CustomActions/PhiSilicaPasteProvider.cs`): an on-device AI provider backed by the Windows AI Phi Silica language model — no cloud endpoint or API key required. Registered as a new `AIServiceType` via `PasteAIProviderFactory` / `AIServiceTypeRegistry`. - **Additional custom actions** (`AdvancedPasteAdditionalAction`): user-defined actions with their own prompt, system prompt, AI provider, and shortcut — plus an optional "coaching" prompt/system-prompt/provider/shortcut and shortcut-conflict detection. - **Built-in default prompts** (`AdvancedPasteDefaultPrompts`) and updates to `AdvancedPasteCustomAction`, `PasteFormat(s)`, `OptionsViewModel`, and `PasteFormatExecutor` to support per-action provider selection and system prompts. - **Settings UI** (`AdvancedPastePage.xaml`/`.xaml.cs`, `Resources.resw`): configure the Phi Silica provider, choose a provider per action, edit system/coaching prompts, and a Phi Silica availability/readiness experience — Settings queries the Advanced Paste executable via `--check-phi-silica`, and a **"Download model"** action triggers `--prepare-phi-silica` to fetch the model and then re-probes. ## Package identity for Windows AI (replaces the MSIX-install approach) - Phi Silica is a **Limited Access Feature (LAF)** that can only be unlocked by a process with a registered **package identity**. Advanced Paste runs unpackaged, so it obtains identity from the existing **`Microsoft.PowerToys.SparseApp`** sparse package (`src/PackageIdentity/`): a new `<Application Id="PowerToys.AdvancedPasteUI">` entry in `AppxManifest.xml` maps it to `PowerToys.AdvancedPaste.exe`, with matching updates to `BuildSparsePackage.ps1`. - **LAF unlock** at runtime via `PhiSilicaLafHelper.cs`. The token/attestation are baked at build time by the `GeneratePhiSilicaLafCredentials` MSBuild target into `PhiSilicaLafCredentials.g.cs` — local **dev defaults** live in `src/PhiSilicaLaf.props` (imported from `Directory.Build.props`) and the **production secret** is injected via `/p:` in the release pipeline. - New **`AdvancedPaste.dev.manifest` / `AdvancedPaste.prod.manifest`** application manifests (selected by `CIBuild`) declaring full-trust and the system AI models capability. ## Build & pipeline - **Windows App SDK** moved to the coherent **stable `2.2.0`** line and **added `Microsoft.WindowsAppSDK.AI` `2.2.3`** (the Phi Silica APIs). Foundation `2.1.0` carries the sparse-identity PRI fix, and the stable AI build matches the OS Windows AI runtime. - **Independent versioning** for Advanced Paste (`src/modules/AdvancedPaste/custom.props`, XES one-store versioning, `AdvancedPasteVersion`). A `steps-setup-versioning.yml` step is added for Advanced Paste in `job-build-project.yml`, ordered **before** CmdPal to avoid a version-collision installer failure (WIX0103). - `release.yml` passes `PhiSilicaLafToken`/`PhiSilicaLafAttestation` into the main build; spell-check allow-list/patterns updated. - Removed now-unneeded dependencies: the `Microsoft.Windows.Compatibility` reference and the `Common.UI` "force matching DLL versions" hack. <img width="1073" height="716" alt="image" src="https://github.com/user-attachments/assets/9364d86a-c0d1-4a08-a669-d98cbcb4b140" /> <img width="1038" height="308" alt="image" src="https://github.com/user-attachments/assets/00eef1dd-b407-4841-bd64-f54f8a145c46" /> <img width="194" height="405" alt="image" src="https://github.com/user-attachments/assets/d2f9c5bb-2507-4112-b3e0-56da681f88ea" /> <img width="489" height="453" alt="image" src="https://github.com/user-attachments/assets/811d1afd-9993-48be-824e-82bb56c5ceca" /> [Video clip internal](https://onedrive.cloud.microsoft/✌️/a@9n6nl3fp/S/cQpvAHrL5M9ZR6eUawztyfyBEgUCwCF-aKg9TbKyyGWP4c0KMA) [Build internal](https://microsoft.visualstudio.com/Dart/_build/results?buildId=149920754&view=artifacts&pathAsName=false&type=publishedArtifacts) --------- Co-authored-by: Niels Laute <niels.laute@live.nl> Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
