Habit-Forming Products — The Hook Model

Use When

• Use when designing products, features, or onboarding flows that need to build unprompted repeat engagement — daily/weekly return without ads or reminders. Covers the Hook Model (Trigger → Action → Variable Reward → Investment), internal trigger...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to habit-forming-products or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
