What problem does it solve? Operations work often stalls on judgment rather than execution—deciding whether an initiative is worth doing, which metrics to watch, and how to structure user operations. This Skill distills the cognitive frameworks of Zhang Liang (author of "Starting Operations from Zero") into a callable advisory perspective for operations system design and execution quality review. ## Core Features & Use Cases - Four-Module Operations Audit: Uses the content/user/activity/product operations checklist to find gaps in your operations plan. - User Lifecycle Strategy: Applies the acquire-retain-maintain-stimulate model to design stage-specific user operations and tiered user management. - Decision Heuristics: Provides six if-then rules covering activity leverage, post-campaign review (cost + KPI principles), and data fluctuation diagnosis. - Use Case: Paste your user retention plan and ask for a Zhang Liang perspective review; receive a conditional analysis of lifecycle stage fit, habit-forming mechanisms, and honest limitations of the framework. ## Quick Start Ask the agent to invoke operations-advisor-zhang and analyze your operations plan, campaign proposal, or user metrics from the Zhang Liang perspective.
