SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OpenCode Game development often stalls when teams guess whether a mechanic will feel right, so this Skill helps you test a clear hypothesis quickly and decide whether to proceed, pivot, or kill the concept.

Core Features & Use Cases

Defines a single core question for the prototype so effort targets what matters most for validation.
Builds a timeboxed throwaway implementation with intentionally relaxed standards (no production refactors, minimal scaffolding).
Produces a structured prototype report including hypothesis, measured observations, metrics, and an evidence-based recommendation.
Optionally runs a creative director review gate (full mode) to align outcomes with the game’s pillars and core fantasy.

Quick Start

Run the prototype skill with your concept description and an optional review mode flag to generate a prototype directory and a complete prototype report.

FAQPage Schema

How do I validate a game mechanic quickly before committing to full development?▼

To validate a game mechanic quickly, define a single core question and build a timeboxed throwaway prototype to test it. This approach uses intentionally relaxed code standards to measure feel and viability within 1 to 3 days of effort.

What is the best way to structure a game prototype report for mechanic validation?▼

A game prototype report should include your core hypothesis, measured observations, metrics, and an evidence-based recommendation. This structure helps you decide whether to proceed, pivot, or kill a concept based on validated results.

Can I use throwaway prototyping to test early-stage game ideation concepts?▼

Yes, throwaway prototyping is designed for early-stage ideation, mechanic feel checks, and timeboxed proofs of viability. It enforces a non-production code policy to ensure effort targets what matters most for validation without refactoring overhead.

Does game prototyping workflow gating require a creative director review?▼

Game prototyping workflow gating optionally routes full reports through a creative director review task to align outcomes with game pillars. Review mode is selected from arguments or configuration files to enforce this validation gate.

How does timeboxing scope to 1-3 days effort improve game prototyping?▼

Timeboxing scope to 1-3 days effort improves game prototyping by restricting development to a single core question using minimal scaffolding. This prevents over-investment in unproven concepts and accelerates the decision to proceed or pivot.

What are the limitations of using throwaway prototypes for game development?▼

Throwaway prototypes use intentionally relaxed standards with no production refactors and minimal scaffolding, meaning the generated code is not suitable for final production. They serve strictly to validate mechanic feel and viability rather than building architecture.
