What problem does it solve? Shipping a game involves dozens of platform-specific requirements, and attempting an export for a target whose template is not installed produces confusing failures or broken builds. This Skill inventories the export templates actually present in the installed Summer Engine build, runs a pre-flight checklist, and produces verified local builds only for proven targets. ## Core Features & Use Cases - Capability inventory: Reads the engine binary path and installed export templates to classify each target (macOS, Windows, Linux, Web, Android, iOS) as available, missing a prerequisite, or impossible on the current build. - Pre-flight validation: Checks main scene, script errors, debug print spam, hardcoded paths, version number, LICENSE, attribution, and .gitignore before any export. - Per-platform requirement lists: Provides asset and configuration checklists for Steam, itch.io, Web, iOS App Store, Google Play, macOS DMG, and Windows installer. - Use Case: A developer says "ship my game to Steam and itch." The Skill proves macOS is the only locally available target, runs the pre-flight checklist, fixes blockers, then produces a verified release build and hands off the upload commands (steamcmd, butler) to the user. ## Quick Start Ask the agent to assess which export targets are available in this project and prepare a release build for the ones that pass the pre-flight checklist.
