Supporting Artifacts

The GDD is supported by separate documents:

GDD Creation Workflow

Step 1: Repository Analysis

Gather context about the project:

# Read project files for context
Read("README.md")
Read("package.json")
Read("prd.json")
Glob("src/**/*")  # List source files

Document:

• Project type and genre
• Current implementation status
• Technology stack
• Team size and structure

Step 2: Research Phase

Use web-search and GitHub MCP:

• Research similar games
• Find reference implementations
• Document inspirations
• Identify best practices

Step 3: Design Sessions

Use thermite-design skill for structured sessions:

• Boardroom Retreat for core concepts
• Deep Dive for specific domains
• Decision Review for validation

Step 4: Draft GDD

Create the main GDD document with all sections.

Step 5: Iterate

Refine through self-iteration and team feedback.
