Use when the user types "/summer <anything>" — 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.
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 card art".
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 this character look like", "mood board", "rough sketches".
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 "asset sheet", "asset pack", "tile sheet", "tileset", "UI kit", "asset pack for", "make me a sheet of", "generate a bunch of <category> assets".
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 order, and emits the Sprite2D / Node2D / NinePatchRect ops to lay it out correctly. Trigger on "import the X pack", "spawn the UI from pack Y", "bring in that asset sheet", "add the panel from the pack".
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".
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".
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 animation".
