What problem does it solve? Manually launching a game project and checking whether it started cleanly is repetitive, and silent script compile errors or runtime crashes are easy to miss. This Skill runs the project in Summer Engine, waits for real frames to process, and reports a clear verdict: clean run, warnings, or a crash with file and line details. ## Core Features & Use Cases - Pre-flight compile check: Calls summer_get_script_errors on recently edited scripts (or summer_get_diagnostics project-wide) before playing, so compile failures surface before a noisy launch. - Controlled run and inspection: Clears the console, starts play with summer_play, waits about two seconds, then reads diagnostics and debugger errors for an accurate report. - Scene targeting and safe behavior: Supports launching a specific scene via a full res:// path, asks before restarting an already-running game, and never auto-stops the session. - Use Case: After editing player movement code, ask the agent to play the game; it verifies the script compiles, launches the project, and reports either a clean run or the exact crash location. ## Quick Start Ask the agent to play the game and tell you whether it runs cleanly or hits any errors.
