SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when starting a multiplayer Summer game from scratch with peer-to-peer host authority. Build the network architecture top-down so authoritative state, routing rules, and real-time rendering are not bolted on later. Use before writing game logic, not after. Trigger on "multiplayer", "peer-to-peer", "p2p", "co-op"…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user wants to add multiplayer to an existing Summer game: co-op LAN, co-op online, competitive PvP, or a lobby. Start with Summer Engine's high-level MultiplayerAPI plus MultiplayerSpawner and MultiplayerSynchronizer; use custom networking only with a justified reason. Walks peer authority, RPC patterns…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user reports the game is slow, drops framerate, stutters, takes forever to start, or runs poorly on specific hardware. Profiles the running game via summergetdiagnostics, identifies hotspots (rendering / physics / scripting), and proposes specific fixes with before/after metric expectations. Trigger on…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when setting up lighting in a Summer Engine 3D scene — adding lights, configuring WorldEnvironment, sky, or shadows. Covers DirectionalLight3D versus Omni versus Spot, shadow tuning, ambient and sky-driven lighting, and the current Summer rendering conventions. Trigger on "lighting", "shadows", "WorldEnvironment"…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when defining the visual style of the game — references, palette, mood, lighting plan, post-processing, do/don't list. Outputs an art bible at .summer/art-bible.md. Trigger on "art direction", "art bible", "visual style", "color palette", "what should it look like", "the look".
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user wants help deciding what game to make, scoping a new project, or turning a vague idea into a buildable plan. Walks through genre, scope, core loop, mechanics, and art direction, then writes a 1-page brief to .summer/GameSoul.md. Trigger on "brainstorm a game", "what should I make", "I want to make a…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user wants to see available Summer Engine project templates, start from an existing template, or asks "what templates exist?" — fetches the live list from github.com/SummerEngine, presents the choices, and creates a project from the chosen template via summer create . Trigger on "templates", "starter"…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user says "make me a game", "build me a game", "I want to make a [genre] game", "let's build something" — the orchestration spine that runs the full game-dev pipeline: brainstorm → plan → scaffold → build core mechanics → art direction → audio → polish/VFX → verify → ship. Delegates to specialist skills…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user wants a fresh blank Summer Engine project — not from a template. Asks one question (project name) and runs summer create empty . Trigger on "new project", "blank project", "empty project", "from scratch", "start fresh", "create new game", "blank canvas", "scaffold a project".
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user says "play", "run it", "test it", "let me see it", or "start the game". Runs the project in Summer Engine, briefly waits, then reports what's happening — clean run, errors, or warnings.
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when building or organizing Summer Engine scenes: node hierarchy conventions, when to extract sub-scenes, reusable prefab patterns, and instance-versus-add-node decisions. Trigger on "scene", "sub-scene", "instance", "prefab", "node hierarchy", "scene structure", "PackedScene".
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when the user wants to sync a Summer Engine project, move it to another machine or laptop, share the exact bytes with a collaborator, back up big generated assets that do not belong in git, restore an earlier version, or wants a safety net before a risky bulk operation. Trigger on "sync", "Summer Cloud", "cloud…
SummerEngine/summer-engine-agent
Skill Claude CodeCodex
Use when writing or refactoring GDScript — type hints, signals, exports, onready, lifecycle methods (ready vs process vs physicsprocess), getnode vs $NodePath, naming conventions. Trigger on "GDScript", "script", "signals", "exports", "onready", "ready", "process".
