What problem does it solve? It verifies that a Godot game actually works before shipping by running native gameplay assertions headlessly and producing a Web export only when those checks pass, replacing manual playtesting of every change. ## Core Features & Use Cases - Gameplay proof harness: Runs scripts/proof.gd headlessly to instantiate real gameplay, assert state transitions, and write a proof.json receipt; a missing or failing receipt fails the build even if Godot exits zero. - Sandboxed Web export: Copies project source into fresh staging (excluding build/cache directories), imports assets, and exports the Web preset into build/web while preserving the previous export until the new one succeeds. - Browser performance probe: Optionally measures real interaction frame timing in the shared Web Viewer via Playwright using the assertions recorded in proof.json. - Use Case: After adding a new mechanic to a Godot Studio project, run the export script to confirm the gameplay assertions pass and get a playable single-threaded Web build for the live viewer. ## Quick Start Ask the agent to build and export the Godot project in the current workspace so it runs the gameplay proof and produces a Web build.
