What problem does it solve? Building the Echo Visualizer app requires coordinating a Rust DSP engine, a C# WinUI 3 frontend, FFI integration tests, and MSIX packaging with certificate signing. This Skill automates that entire pipeline so you avoid manual multi-toolchain errors and inconsistent build outputs. ## Core Features & Use Cases - Full Pipeline Execution: Run environment verification, Rust and C# tests, compilation, and MSIX packaging with a single PowerShell command. - Step-by-Step Control: Execute individual stages (environment check, tests, binary build, certificate trust, MSIX install) for debugging or CI customization. - Troubleshooting Guidance: Built-in fixes for common failures like missing Cargo in PATH, platform mismatches, and certificate trust errors. - Use Case: A developer clones the repository on a new Windows machine and needs a signed, installable MSIX package. The Skill verifies the .NET 8 SDK and Rust toolchain, runs all tests, builds x64 binaries, trusts the dev certificate, and produces the installer. ## Quick Start Ask the AI to build and deploy the Echo Visualizer app from the repository root using the full build pipeline with both GitHub and Store profiles.
