SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Forge a project codex creates a structured, repeatable workflow to capture development context, open knowledge gaps, and a living, searchable reference for GDD-driven projects.

Core Features & Use Cases

  • RECON-PLAN generation and per-vector synthesis (competition, tech-stack, techniques, optimization, level-design, programming-patterns)
  • Atomic-note drafts and MOC updates to keep Vault consistent
  • Log integration and cross-reference linking to the GDD and codex outputs

Quick Start

Invoke /forge-codex after a locked GDD to generate the full codex or refresh a single vector as needed.

FAQPage Schema
How do I automate research documentation for a game development project?▼

You automate research documentation by generating a project codex that captures open knowledge gaps, sources, and architectural decisions. This creates a living reference structured with RECON-PLAN.md and per-vector syntheses directly from your GDD.

What is a project codex and how does it work with a GDD?▼

A project codex is a searchable research reference that documents development context for GDD-driven projects. It works by using the GDD hash to enforce idempotency, ensuring your codex outputs remain consistent and locked to the current design state.

How do I generate atomic notes and MOC updates for my vault?▼

You generate atomic notes and MOC updates by running the codex workflow, which automatically drafts these elements under Vault/40-Projects/<slug>/codex/. This keeps your vault consistent and cross-referenced with your GDD.

Do I need a locked GDD to create project research syntheses?▼

Yes, you need an existing locked GDD and an associated vault structure to create project research syntheses. The workflow uses your GDD as the foundational input to generate targeted vectors like competition, tech-stack, and programming patterns.

How are sources verified when documenting architectural decisions?▼

Sources are verified using a 2X cross-check rule, sourcing all claims from primary sources when possible. This ensures that your documented architectural decisions and open knowledge gaps are reliable and traceable.

Can I refresh a single research vector without regenerating the entire codex?▼

Yes, you can refresh a single research vector like level-design or optimization without regenerating the entire codex. The workflow supports targeted generation, allowing you to update specific syntheses while maintaining overall idempotency.
