SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes assets (resource) components.

What problem does it solve?

asset-spec prevents your game art pipeline from drifting by converting approved GDDs/level docs/character profiles into consistent, structured, per-asset visual specs that match your art bible rules and technical constraints.

Core Features & Use Cases

  • Guided context selection: Reads design/assets/asset-manifest.md to find the next unspecced system/level/character context, or accepts explicit targets via command arguments.
  • Asset list confirmation before work: Extracts all asset types implied by the source docs, then prompts you to review the full grouped asset list before generating any specs.
  • Art + technical spec generation (review modes): In full mode, generates both art-direction prompts and technical constraints using specialist agents; in lean mode, skips the technical constraint pass; in solo mode, derives specs from art bible rules without spawning agents.
  • Review and controlled writing: Compiles drafted specs per asset, asks for approval, writes to design/assets/specs/[target-name]-assets.md, then updates design/assets/asset-manifest.md to track progress.

Quick Start

Run the command /asset-spec system:tower-defense to generate and review asset specs for the specified system.

Frequently Asked Questions about asset-spec

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate consistent visual specifications for game assets from a GDD?

You can generate visual specifications by feeding your approved Game Design Document into an asset spec generator that extracts asset needs and aligns them with your art bible rules. This ensures per-asset visual specs remain consistent and technically validated before production begins.

How to maintain art bible alignment across a game asset production pipeline?

Maintain art bible alignment by converting approved design documents into structured per-asset visual specs that match your technical constraints. The system validates art direction prompts against your defined rules, ensuring every generated asset specification adheres to the established visual consistency standards.

Can I generate AI image prompts directly from my game design documents?

Yes, you can generate AI image prompts directly from design documents by extracting target-specific asset needs and applying art direction rules. The system compiles drafted prompts for each asset, asks for your approval, and writes structured spec files to your designated directory.

Do I need an existing asset manifest to start generating asset specs?

You do not strictly need an existing manifest to start, as the system can accept explicit targets via command arguments. However, having a master asset manifest allows the system to automatically identify the next unspecced context and track production progress accurately across your pipeline.

What is the best way to track production progress for game art assets?

The best way to track production progress is by maintaining a master asset manifest that updates automatically when new specifications are written. This approach links approved design documents directly to individual asset spec files, providing a tracked overview of your entire game art pipeline.
