Generate 2D Sprite

Make the smallest asset bundle the game needs, at its real display size, camera and style. Game logic (collision, damage, timing) stays independent of the art.

Use when

• A character, creature, prop, item, icon or FX is needed as a master still, a sheet or clips.
• Frames already exist (generated, painted, code-drawn) and need clips, palettes or an engine export.

Do not use when

• Maps, tiles, terrain, parallax or scene plates: generate2dmap.
• Animating a character: approve one master here, then video2dsprite makes one clip per action (video-handoff.md).
• Code-drawn art the user asked for: codeart2d. Only an API or CLI call: generate2dmedia.

Capability check (once per session)

Run python "<skill-dir>/../generate2dmedia/scripts/forge_doctor.py" --host-tools <tools> --save <output>/doctor.json, where <tools> lists the media tools in your own tool list (image_gen, image_edit, image_to_video) or none. Its ROUTES block shows which API keys are configured (yes or no), the local readiness and the resolved order. If encoding.stdout fails, set PYTHONUTF8=1.

Art source

Image generation is the default art source for characters, creatures, props, icons and FX. Record it as art_source (api, host_image, existing, or code only on request) and name the route in your reply. A route the user names explicitly wins.

1. API, when a key is configured: OpenAI (OPENAI_API_KEY), Google Gemini (GEMINI_API_KEY), xAI (XAI_API_KEY), BytePlus Seedream (ARK_API_KEY) or fal.ai (FAL_KEY), in the environment or the user config file (route-media.md). The configured key is the owner's consent, so there is no per-call question.
2. Local: your own image tool (Codex image_gen, Grok's native tool) when you have one, otherwise the user's signed-in Codex CLI, then Grok CLI.
3. codeart2d only when the user explicitly asks for code-drawn art, or when route_media.py prints no-route (exit 3). Then say "code-drawn, no image model".
