game-character-gen_skill

Overview

This skill generates professional game character designs and artwork using the OpenAI Images API. It produces character images, optional JSON character sheets, and a gallery of prompts and outputs. Use it to create concept art, portraits, sprites, and reproducible character data for games and interactive media.

How this skill works

Provide race, class, equipment, style, and optional custom prompt or batches; the tool composes detailed image prompts and calls the OpenAI image model to render character art. It can output one or many variants, save PNG files, and optionally produce a character_sheet.json with stats and metadata. Advanced options let you control size, quality, model, and include a full custom prompt that overrides parameterized input.

When to use it

• You need quick concept art or portraits for RPGs, video games, or tabletop campaigns.
• You want consistent character portraits across a party or NPC roster.
• You need batch generation for multiple races, classes, or stylistic variants.
• You require both images and structured character sheets for integration into game tools.
• You want to prototype visual identities (pixel art, concept art, anime, photorealistic).

Best practices

• Start with clear race/class/equipment/style parameters for predictable results.
• Use the --prompt option for precise, cinematic descriptions when you need a specific look.
• Generate batches with consistent style values to maintain visual cohesion across characters.
• Enable --sheet to get JSON stat blocks and an image reference for pipeline automation.
• Keep equipment and expression keywords concise and prioritized for the best prompt focus.

Example use cases

• Create an epic fantasy party: elf ranger, human paladin, dwarf cleric in a unified oil-painting style.
• Generate a cyberpunk crew with hackers, cyborg soldiers, and neon-drenched portraits for a visual novel.
• Produce pixel-art sprites for a retro-style game with multiple color and class combinations.
• Export character sheets and portraits to seed NPCs for tabletop campaigns or VTT assets.
• Batch-produce variant portraits for character creation screens in an RPG prototype.
