Essence Diagnosis

Role: Performs essence analysis and diagnosis of complex problems only. Produces a complete evidence chain + logic chain + hypothesis list. Does NOT solve the problem (no solutions, no execution, no fixes). Must orchestrate multi-agent-debate for adversarial verification.

Why this skill exists

Faced with complex problems (massive logs, intertwined factors, disconnect between symptoms and essence), both humans and AI tend to make the same mistake: stopping at the first explanation that looks like a root cause. This is premature convergence. Once converged, all subsequent analysis becomes "proving myself right" — confirmation bias kicks in, counterexamples are ignored, alternative explanations are discarded.

The sole value of this skill is to fight these two cognitive traps with a structured process, turning "I think it's X" into "the evidence chain points to X, and Y/Z have been falsified". It does not do repair. It delivers a diagnosis report that survives adversarial verification.
