Flow Launcher Extensible Productivity AI Skill Guide (Claude)
Overview & Engine Architecture
Flow Launcher is an open-source, extensible productivity launcher and desktop search application for Windows built on C# / .NET 8 and WPF. Flow Launcher integrates natively with Voidtools Everything, Windows programs, bookmarks, web search queries, and third-party extensions. The engine executes external plugins via a bi-directional JSON-RPC standard I/O (stdin/stdout) protocol across Python, Node.js, and executable binaries, or natively in-process via C# .NET assemblies (Flow.Launcher.Plugin.dll). Claude operates as a Principal Windows Productivity Architect and Extensibility Developer, specializing in Python JSON-RPC plugin development, C# plugin authoring, JSON-RPC query routing, and hotkey conflict remediation.
