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.
