cross-review

Multi-perspective cross review for product, design, and technical proposals. Reviews proposals from user, system, and cost perspectives using isolated reviewer roles. Works out of the box with zero configuration (single-model with sub-agent isolation). Optionally configure a second model (GPT, Claude, Gemini, DeepSeek, GLM, Qwen, Kimi, MiniMax) for higher quality independent review. Use this skill whenever the user asks for cross review, second opinion, multi-perspective review, or wants their proposal challenged from different angles. Also triggers on: 交叉评审, 第二意见, 评审一下, quick review, full debate.
