What problem does it solve? Passing tests do not prove an application actually works when a real user launches it. This Skill closes that gap by launching the real app — the CLI at its command, the server at its socket, the GUI at its window — and driving it to a visible result, so you can confirm a change works in practice rather than only in unit tests. ## Core Features & Use Cases - Project Skill Discovery: Searches the repository hierarchy for an existing project skill that already documents how to launch the app, and follows that verified path verbatim before falling back to generic patterns. - Per-Type Run Recipes: Provides launch-and-drive patterns for CLI tools, web servers, TUIs (via tmux send-keys/capture-pane), Electron apps (Playwright under xvfb), browser-driven web apps, and libraries. - Interaction Verification: Goes beyond launching by driving the app to a user-visible outcome — running a command, curling a route, capturing a pane, or taking and inspecting a screenshot. - Use Case: After modifying a TUI dashboard, use this Skill to launch the app in tmux, send navigation keys, capture the pane, and confirm the changed screen renders correctly. ## Quick Start Ask the agent to run the app and confirm your recent change works in the real interface, not just in tests.
