When you're juggling multiple tasks and everything's moving slowly, this forces a hard stop to pick one target and finish it completely before moving on. It's built on Mao's military principle of concentrating superior force against isolated enemies rather than spreading thin. The skill triggers a priority matrix that considers impact, difficulty, and dependencies, then locks you into a single objective with explicit "paused tasks" you won't touch until the main one ships. It pairs with contradiction analysis to find which problem actually matters and blocks you from context switching when new requests come in mid-flight. Honestly most useful when you catch yourself half-finishing everything, which is most of the time.
