SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when the user types "/summer " — adopts the Summer Engine game-dev persona and routes the request through the Summer skill family. Trigger on any message starting with "/summer ", or "as Summer" / "in Summer mode" / "using Summer" framings.

SummerEngine/summer-engine-agent

Command

You are capturing what we just learned in this game-development session into Summer Engine's skill library, so the next agent (and every Summer user) gets to start where we ended.

SummerEngine/summer-engine-agent

Command

You are the Summer Engine command router. The user invoked /summer because they want game-development help inside Summer Engine, not generic software advice.

SummerEngine/summer-engine-agent

Hook

Runs when a session starts on startup, clear and compact, executing run-hook.cmd. From SummerEngine/summer-engine-agent.

SummerEngine/summer-engine-agent

Hook

Runs before the agent uses a tool for Bash(git commit*) tool calls, executing run-hook.cmd. From SummerEngine/summer-engine-agent.

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating a single, polished bust/portrait of a character for dialogue UI, character-select screens, lore cards, or codex entries. One character, locked composition, VN-style. Trigger on "character portrait", "dialogue portrait", "VN portrait", "character bust", "headshot", "character select image", "lore…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when the user is exploring art direction — wants 3-4 rough variants of a character, environment, or prop to pick a vibe before committing to a final asset. Generates a batch of evocative concept images, not finals. Trigger on "concept art", "art direction", "explore the look", "give me some variants", "what could…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when the user wants to generate a pack of 2D game assets from a single prompt — a tile sheet, UI kit, menu screen, character pack, or biome set. The skill plans the prompt, generates a coherent sheet, removes the background, vision-detects each item, classifies it, and saves as a single pack ArtAsset. Trigger on…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when the user wants to import or spawn an entire asset pack (the multi-slice ArtAsset produced by create-asset-sheet) into the current scene — not a single slice, the whole pack. Reads the pack's per-slice metadata (zOrder, isComposite, parentSliceIndex, widget, bbox), groups composites, sorts children by paint…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating pixel-art assets — sprites, items, tiles, portraits in a pixel style at a specific resolution (32×32, 64×64, 128×128). Pixel-perfect grid, limited palette, retro feel. Trigger on "pixel art", "8-bit art", "16-bit sprite", "pixel sprite", "retro tileset", "pixel icon", "pixel portrait".

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating a 360° panoramic sky image for use as a Sky resource (PanoramaSkyMaterial) in a 3D scene. Equirectangular projection, 2:1 aspect. Wires into WorldEnvironment.sky. Trigger on "skybox", "sky panorama", "360 background", "environment sky", "HDRI sky", "panoramic background", "panorama sky".

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating animated 2D character sprites laid out as a sprite sheet (grid of frames) — walk cycle, attack frames, idle bob, death sequence. Wires into AnimatedSprite2D / SpriteFrames. Trigger on "sprite sheet", "walk cycle", "attack frames", "animated sprite", "frame-by-frame animation", "2D character…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating a seamless tileable texture for walls, floors, terrain, ceilings — square tile that repeats cleanly on all four edges. Wires onto PlaneMesh / CSGBox3D / MeshInstance3D as a StandardMaterial3D albedo. Trigger on "tileable texture", "seamless texture", "wall texture", "floor texture", "ground…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating UI elements — icons, buttons, panels, frames, HUD widgets, badges. Flat-design, transparent-background, game-UI style. Wires the result via TextureRect / NinePatchRect / AtlasTexture. Trigger on "UI icon", "button graphic", "HUD element", "panel frame", "menu background", "inventory slot", "ability…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when consuming a widget slice (panel, button, slider, progress bar, or toggle pair) from a create-asset-sheet pack in a Summer Engine scene. The pack's metadata.sliceMeta carries 9-slice margins, fill rects, and on/off pair links per slice. This skill explains how to wire those into NinePatchRect…

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating a humanoid character ready for animation — player avatar, NPC, enemy, boss, companion. Generates a T-pose reference image, gates an un-rigged preview past the user, then runs the Meshy auto-rig pass and wires the result as a CharacterBody3D (movement) or Node3D (cinematic). Trigger on "make a…

SummerEngine/summer-engine-agent

SummerEngine/summer-engine-agent

Skill Claude CodeCodex

Use when generating organic shapes — trees, rocks, mushrooms, coral, bushes, alien plants, vines, crystals, fruit, bones. The "easy mode" of 3D generation; AI artifacts read as natural irregularity. Trigger on "make a tree", "generate rocks", "I need foliage", "mushroom prop", "alien plants", "fill the scene with…
