Instructions

你是概念解剖师。拿到一个概念,从八个方向切开它,最后把所有切面压成一句顿悟。

1. 定锚

  1. 这个概念最通行的定义是什么?常见误解在哪?
  2. 概念里藏着哪几个核心词素?

2. 八刀

八个方向各切一刀。每刀 2-3 句,只留筋骨,不带水分。

  1. 历史:最早从哪冒出来 → 怎么变的 → 哪一步拐成了今天的意思
  2. 辩证:它的反面是什么 → 正反碰撞后,更高一层的理解是什么
  3. 现象:扔掉所有预设,回到事情本身 → 用一个日常场景把它还原出来
  4. 语言:拆字源(中/英/希腊/拉丁)→ 画出相邻概念的语义网 → 这个词暗含什么隐喻
  5. 形式:写一个公式或形式化表达 → 公式在哪里失效
  6. 存在:这个概念改变了人怎么活着
  7. 美感:它美在哪?用一个具体意象呈现
  8. 元反思:我们在用什么隐喻理解它?这个隐喻挡住了什么?换一个会怎样

3. 内观

  1. 变成这个概念本身,用第一人称看世界。3-5 句。
  2. 八刀之中,哪几刀指向同一个深层结构?把它提出来。

4. 压缩

  1. 公式概念 = ...
  2. 一句话:用最简单的话说出最深的理解
  3. 结构图:纯 ASCII 画出概念的骨架(只用 +-|/<>*=_.,:;!'" 等基本符号,不用 Unicode 绘图字符)

5. 写入

格式规则(零例外):

  • 输出必须是纯 org-mode 语法,禁止任何 markdown 语法
  • 加粗用 *bold*(org-mode),不用 **bold**(markdown)
  • 分隔线用空行或 org 标题层级区分,不用 ---(markdown 分隔符)
  • 列表用 - item1. item,不用 markdown 的 * item(因为 * 在 org 中是标题)
  • 代码用 ~code~=code=,不用反引号

整合为 org-mode,结构:

#+title: 概念解剖:{概念名}
#+filetags: :concept:
#+date: [YYYY-MM-DD]

* 定锚
* 八刀
** 历史
** 辩证
** 现象
** 语言
** 形式
** 存在
** 美感
** 元反思
* 内观
* 压缩

写入文件:

  1. 运行 date +%Y%m%dT%H%M%S 获取时间戳。
  2. 写入 ~/Documents/notes/{timestamp}--概念解剖-{概念名}__concept.org
  3. 报告路径,完成。
how to use ljg-learn

How to use ljg-learn on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • Cursor installed and configured on your development machine
  • Node.js version 16.0+ with npm package manager (verify with node --version)
  • Active project directory or workspace where you want to add ljg-learn
2

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/lijigang/ljg-skills --skill ljg-learn

The skills CLI fetches ljg-learn from GitHub repository lijigang/ljg-skills and configures it for Cursor.

3

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?
│ ── Universal (.agents/skills) ── always included ────
│ • Amp
│ • Antigravity
│ • Cline
│ • Codex
│ ●Cursor(selected)
│ • Cursor
│ • Windsurf
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/ljg-learn

Reload or restart Cursor to activate ljg-learn. Access the skill through slash commands (e.g., /ljg-learn) or your agent's skill management interface.

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

Make data-driven prioritization decisions faster

Stakeholder Communication

Draft PRDs, status updates, and stakeholder presentations

Example

Create executive summary of Q3 roadmap, monthly progress report, feature launch announcement

Save 3-5 hours/week on communication overhead

Implementation Guide

Prerequisites

  • Claude Desktop or compatible AI client
  • Access to product documentation and roadmap tools (Jira, Notion, etc.)
  • Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
  • Stakeholder contact information and communication channels

Time Estimate

30-60 minutes to see productivity improvements

Installation Steps

  1. 1.Install product management skill
  2. 2.Start with user story generation for known feature
  3. 3.Progress to competitive analysis: research 2-3 competitors
  4. 4.Use for roadmap prioritization: apply RICE/ICE scoring
  5. 5.Draft stakeholder communications and refine based on feedback
  6. 6.Build template library for recurring PM tasks
  7. 7.Share effective prompts with product team

Common Pitfalls

  • Not validating competitive research—verify facts before sharing
  • Accepting user stories without involving engineering team
  • Over-relying on frameworks without qualitative judgment
  • Not customizing outputs to company culture and communication style
  • Skipping stakeholder validation of generated requirements

Best Practices

✓ Do

  • +Validate research and competitive analysis with real data
  • +Collaborate with engineering when generating technical requirements
  • +Customize frameworks and templates to your company context
  • +Use skill for first drafts, refine with stakeholder input
  • +Document successful prompt patterns for PM tasks
  • +Combine AI efficiency with human judgment and intuition

✗ Don't

  • Don't publish competitive analysis without fact-checking
  • Don't finalize user stories without engineering review
  • Don't make prioritization decisions solely on AI scoring
  • Don't skip customer validation of generated requirements
  • Don't ignore company-specific context and culture

💡 Pro Tips

  • Provide context: company goals, constraints, customer feedback
  • Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
  • Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
  • Use skill for 70% generation + 30% customization to company needs

When to Use This

✓ Use When

Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.

✗ Avoid When

Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

Learning Path

  1. 1Basic: user stories, feature specs, status updates
  2. 2Intermediate: competitive analysis, prioritization frameworks, PRDs
  3. 3Advanced: product strategy, go-to-market planning, OKR setting
  4. 4Expert: product vision, market positioning, business model innovation
