What problem does it solve? Long play sessions reveal memory leaks, performance drift, state accumulation bugs, and fun fatigue that short playtests never surface, but teams rarely have a structured way to observe and log them. This Skill generates a timed, engine-specific soak test protocol so QA sessions produce consistent, analyzable evidence. ## Core Features & Use Cases - Timed Checkpoint Protocols: Generates observation checkpoints scaled to 30m, 1h, 2h, or 4h soak durations with per-checkpoint logging tables. - Engine-Specific Monitoring Guidance: Provides concrete memory and stability tracking instructions for Godot 4, Unity, and Unreal Engine, including alert thresholds. - Structured Verdict and Issue Tracking: Produces a post-session analysis with leak detection, stability summary, fun fatigue curve, and a PASS / PASS WITH CONCERNS / FAIL verdict. - Use Case: Before a release gate check, a QA lead runs the skill with a 2h duration and 'all' focus, receives a protocol file in production/qa/, and a human tester records memory, stability, and fatigue observations at each checkpoint. ## Quick Start Use the soak-test skill to generate a 2-hour soak test protocol covering memory, stability, and balance for this project.
