SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Game projects often advance between development phases without confirming that required artifacts, reviews, and quality checks are complete, leading to late-stage rework. This Skill formalizes phase transitions by checking required artifacts and quality gates, then issuing a clear PASS, CONCERNS, or FAIL verdict with specific blockers. ## Core Features & Use Cases - Seven-Stage Gate Validation: Checks transitions across Concept, Systems Design, Technical Setup, Pre-Production, Production, Polish, and Release, each with defined required artifacts and quality checks. - Director Panel Assessment: Spawns creative-director, technical-director, producer, and art-director subagents in parallel for multi-perspective readiness review, with solo and lean review modes. - Chain-of-Verification: Challenges its own draft verdict with five disproving questions, at least two answered by re-reading files or re-running checks, before finalizing. - Use Case: Before committing your team to full production, run the Pre-Production to Production gate to confirm the vertical slice is playable, ADRs are accepted, epics exist, and playtest data validates the core loop. ## Quick Start Ask the AI to run a gate check for the production phase and report whether the project is ready to advance with any blockers.

FAQPage Schema
How do I check if my game project is ready for production?

Run the gate check targeting the Pre-Production to Production transition. It verifies the vertical slice is playable, Foundation and Core ADRs are accepted, epics and sprint plans exist, and playtest data confirms the core loop is fun, then returns a PASS, CONCERNS, or FAIL verdict.

What is the difference between gate-check and project-stage-detect?

project-stage-detect is diagnostic, answering where the project currently is. gate-check is prescriptive, answering whether the project is ready to advance with a formal verdict, blockers, and required artifacts.

Can I run a phase gate without the director panel review?

Yes. Pass --review solo to skip all four director subagents, reducing the gate to artifact-existence and quality checks only. Lean and full modes still spawn the creative, technical, producer, and art directors in parallel.

What happens if the vertical slice was never built?

Skipping the vertical slice downgrades the verdict to CONCERNS rather than FAIL, with a warning about late-stage design pivot risk. However, if a slice was built and fails any validation item, the verdict is automatically FAIL.

Does gate-check update the project stage automatically?

Only after a PASS verdict and explicit user confirmation. It writes the new stage name to production/stage.txt, which updates the status line for future sessions, but it always asks before writing.
