SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Game development teams often struggle to determine if they are truly ready to advance to the next project phase, leading to wasted work, broken builds, or design rework when critical gaps are discovered mid-phase. This skill eliminates that guesswork by performing a comprehensive, structured check of all required artifacts, quality standards, and blockers for each phase transition.

Core Features & Use Cases

  • Formal Phase Gate Verdicts: Produces clear PASS, CONCERNS, or FAIL verdicts for transitions between all 7 standard game development stages, from Concept through Release.
  • Comprehensive Readiness Checks: Validates required artifacts (GDDs, architecture docs, playtest reports, etc.), quality standards (test coverage, design review sign-offs, performance budgets), and potential blockers for each phase.
  • Use Case: A team preparing to move from Pre-Production to Production can run this skill to confirm their vertical slice is playtested, all MVP GDDs are approved, architecture ADRs are accepted, and sprint plans are in place before committing to full feature development.

Quick Start

Request a phase gate validation for your target development stage, for example ask if your project is ready to move to Production.

Frequently Asked Questions about gate-check

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

FAQPage Schema
How do I validate game development phase readiness before moving to production?▼

You can check readiness to advance between game development phases by validating required artifacts, quality standards, and phase-specific blockers to receive a formal PASS, CONCERNS, or FAIL verdict.

What is a phase gate check in game development?▼

A phase gate check is a readiness validation process that determines if a game project has the required artifacts and quality standards to advance between development stages, from Concept through Release.

How do I check if my vertical slice and GDD are ready for production?▼

You can validate vertical slice and GDD readiness by running a phase gate check that confirms playtest reports are complete, MVP GDDs are approved, and architecture ADRs are accepted before entering full production.

Can I use a phase gate review for solo game development?▼

Yes, you can use phase gate validation for solo game development, as the review supports solo, lean, and full modes with optional director panel assessments to check readiness across all stages.

What artifacts do I need to pass a pre-production to production gate?▼

To pass a pre-production to production gate, required artifacts include approved MVP GDDs, accepted architecture ADRs, completed vertical slice playtest reports, and established sprint plans.

When should I run a readiness validation during game development?▼

You should run a readiness validation when preparing to transition between any of the 7 standard game development stages, ensuring required artifacts and quality standards are met before committing to the next phase.
