适合增长与产品团队，提升留存与活跃度。
可能涉及促成用户上瘾的设计，应注意伦理与合规。
用Hook模型设计让用户形成使用习惯的产品环路。
用 Hook Model（Trigger、Action、Variable Reward、Investment）设计能让用户反复回归的产品循环，覆盖通知、留存机制、进度体系和上手引导。适合用户回访率低、想做成习惯型产品或要设计复访/打卡/激励机制时用。除了增长思路也会评估伦理边界，防止走到“操控”那一步。

Design habit-forming product loops using the Hook Model (Trigger, Action, Variable Reward, Investment). Use when the user mentions "users arent coming back", "habit formation", "engagement loops", "habit zone", or "the manipulation matrix". Also trigger when designing notification or re-engagement strategies, building streaks or progress systems, or analyzing why users stop after signup. Covers ethics evaluation and onboarding for habits. For friction reduction and B=MAP, see improve-retention. For viral sharing, see contagious.

Framework for building habit-forming products. Habits are not created — they are built through successive cycles through the Hook.
## Core Principle
**The Hook Model** = a four-phase loop that connects the user's problem to your solution frequently enough to form a habit, moving usage from deliberate to automatic.

Trigger → Action → Variable Reward → Investment

## Scoring
**Goal: 10/10.** When reviewing or creating product engagement mechanics, score the loop by the four Quick Diagnostic rows (internal trigger, dead-simple action, variable reward, investment loads ne
