What problem does it solve? Operations and growth decisions often stall on judgment questions rather than execution: which metric to watch, whether an action is worth doing, and how to design a growth experiment. This Skill distills Qu Hui's growth-hacking frameworks (from "The Silicon Valley Growth Hacker's Field Notes") into callable mental models, decision heuristics, and anti-patterns so a data-driven growth perspective is available on demand. ## Core Features & Use Cases - North Star Metric Selection: Apply a 6-question filter to choose a single leading indicator that reflects user value and supports business goals. - Growth Model Decomposition: Break the north star metric into additive (channels/segments) and multiplicative (conversion rates) formulas to locate the weakest lever, using "pour fuel on fire" or "fix the leak" strategies. - Experiment Loop Design: Structure ideas through ICE prioritization, A/B testing, and scale-or-drop cycles with explicit honesty boundaries and source citations. - Use Case: Paste your current growth plan or metric dashboard and ask whether your chosen KPI is a vanity metric, which funnel stage to fix first, or how to design the next two-week experiment cycle. ## Quick Start Ask the agent to analyze your growth question, metric choice, or experiment plan using the operations-advisor-qu perspective.
