When you're stuck on a complex problem with competing priorities or conflicting constraints, this walks you through identifying all the contradictions, isolating the primary one that's driving everything else, and choosing the right resolution strategy based on whether it's antagonistic (pick a side) or non-antagonistic (find common ground). It's adapted from Mao's "On Contradiction" and forces you to output a structured analysis: list all conflicts, mark the main one, classify its nature, state your approach, and set monitoring triggers for when secondary contradictions might escalate. The framework is surprisingly practical for untangling messy technical decisions where trade-offs aren't obvious. Skip it if the task is straightforward execution or the user already told you what to do.
