Product thinking playbook

Skill yangyue1974/product-thinking-playbook

A decision-making playbook for solo product builders. 20 principles across 5 dimensions — Intent, Boundary, Execution, Quality, Closed Loop — extracted from 6 shipped products. Use when starting a new product, stuck on a product decision, reviewing your own work, or collaborating with an AI coder who can write anything but doesn't know what to build.From its SKILL.md

Product Thinking Playbook

A judgment framework for indie developers and product people.
Not a "product manager handbook" — a record of what's actually going through your head in the moment you make a call.
一套给独立开发者 / 产品人的判断框架。不是"产品经理手册"，是把"做决策的那一刻在想什么"写下来。

Each principle file below is bilingual (English first, then 中文).

When to use this skill

Open the corresponding principle before making the call:

  • Starting a new product → principles/01-scenario-first.md → principles/02-spec-before-code.md
  • Feature creep, can't stop adding → principles/05-subtraction-over-addition.md
  • Working with AI, product feels off → principles/11-commander-posture.md
  • Have a batch of bugs, don't know where to start → principles/13-end-to-end-fixes.md + 14-design-vs-execution-error.md
  • Product "works" — what's next? → principles/17-real-engagement-metrics.md + 20-distribution-is-product.md
  • Quick lookup → quick-reference.md

20 principles · index

I. Intent 立意

  1. Scenario-first · 场景先于功能
  2. Spec before code · 先定性，再动手
  3. Aesthetic as stance · 气质即立场
  4. Subtitle as promise · 副标题是承诺

II. Boundary 边界

  1. Subtract, don't add · 做减法而非加法
  2. Vision non-negotiable · 愿景不妥协
  3. Product boundary = user's decision path · 产品边界 = 用户决策路径
  4. Infrastructure mindset · 克制：不是基础设施该做的别做

III. Execution 执行

  1. Decisive & meticulous · 决策果断，细节挑剔
  2. Borrow existing cognition · 借力已有认知
  3. Commander posture · 指挥者姿态
  4. Content standards > technical standards · 内容标准 > 技术标准

IV. Quality 品质

  1. End-to-end fixes · 端到端修复
  2. Design vs execution error · 设计错误 vs 执行错误
  3. Experience before review · 先用再评
  4. Security = product quality · 安全 = 产品品质

V. Closed Loop 闭环

  1. Core metric bound to real engagement · 核心指标绑定真实投入
  2. Persistence is trust · 持久化 = 信任基础
  3. Cross-platform parity + honest permissions · 跨端一致 + 权限诚实
  4. Distribution is part of the product · 分发是产品的一部分

Case studies

Every principle above is grounded in a real project. The full development conversations:

How to invoke

In Claude Code:
> Using product-thinking-playbook, help me decide: should this feature go in now?

In your own head:
> Read through quick-reference.md, find the line that hurts most.

Three core postures · 三个核心姿态

English:

  1. Intent stands firm: scenario, aesthetic, vision — each clearly articulated, you'd push back on a one-character change.
  2. Execution holds up: decisive direction × meticulous detail; you're the commander, not the contractor.
  3. Loop closes: it works → it stands up to scrutiny → users can actually reach it.

中文：

  1. 立意定得住：场景、气质、愿景都能说清楚，别人改一字都不舒服。
  2. 执行扛得住：果断拍板 × 细节不放过，自己是指挥者不是乙方。
  3. 闭环做得到：能跑起来 → 经得起推敲 → 用户真的能用到。
