SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Game development teams often waste hours manually writing inconsistent asset specifications that fail to align with art direction, technical constraints, and design requirements, leading to rework, missed deadlines, and disjointed visual quality across assets.

Core Features & Use Cases

  • Automated Spec Generation: Creates detailed per-asset visual descriptions, AI generation prompts, and technical constraints from GDDs, level design docs, character profiles, and approved art bibles.
  • Asset Pipeline Tracking: Maintains a master asset manifest to track spec status, avoid duplicate work, and coordinate progress across art, design, and production teams.
  • Specialist Agent Coordination: Spawns art director and technical artist agents to validate specs against visual identity rules and engine performance budgets, with fallback modes for fast iteration.
  • Use Case: For a 90s F1-style racing game, this skill can generate specs for all car sprites, track environment props, HUD elements, and VFX effects directly from the GDD and art bible, ensuring every asset matches the retro racing aesthetic and engine performance requirements.

Quick Start

Request the asset-spec skill to generate complete asset specifications for all entities listed in your game's entity inventory, anchored to your approved art bible.

FAQPage Schema
How do I generate consistent asset specifications from a game design document?

To generate consistent asset specifications from a game design document, you can use automated tools to parse your GDD and art bible to create structured per-asset visual descriptions, technical constraints, and AI generation prompts. This ensures alignment with your project's art direction rules and technical performance budgets.

Can I track asset pipeline status and avoid duplicate work using an asset manifest?

Yes, you can track asset pipeline status and avoid duplicate work by maintaining a master asset manifest. This manifest coordinates production progress across art, design, and technical teams by logging spec status for all entities listed in your game's inventory.

Does this approach work for both 2D and 3D game asset pipelines?

Yes, this approach works for both 2D and 3D game asset pipelines. It generates detailed specifications for sprites, VFX, environment props, UI elements, and audio assets for characters, levels, game systems, and UI screens in either format.

How do I validate AI generation prompts against engine performance budgets?

You can validate AI generation prompts against engine performance budgets by spawning specialist technical artist agents. These agents review the generated asset specifications to ensure they comply with your established technical constraints and visual identity rules.

What is the best way to automate art bible compliance for game assets?

The best way to automate art bible compliance for game assets is to extract visual identity rules directly from the approved art bible and apply them during spec generation. This ensures every generated visual description and AI prompt matches the required aesthetic.

How do I spec HUD elements and VFX effects directly from a GDD?

To spec HUD elements and VFX effects directly from a GDD, feed your level design docs and character profiles into a spec generator. It outputs structured visual descriptions and technical constraints specifically tailored for your game systems and UI screens.
