# writing-prds

Turns a vague idea into a short spec with a clear problem, success metrics and project boundaries. Useful before development starts, while the team still argues about what to build.

## What it does

The skill walks through four steps: state the problem without tying it to a solution, define measurable outcomes, narrow a fuzzy request into a bounded concept, then audit the draft for brevity. It ships with questions to ask yourself and the team, plus a list of common mistakes: using the word "just", premature high-fidelity mocks, missing non-goals, and waterfall handoffs that leave designers and engineers out of early planning.

The material comes from Lenny's Podcast and Newsletter: a one-pager template, a five-element rubric for a good PRD, a review checklist, and shaping techniques like breadboarding and fat marker sketching. Details live in `references/artifacts.md` and `references/guest-insights.md`.

The skill advises starting with a single page. If your draft runs three pages about one button, that is a signal you may be stifling the engineers' creativity. Runs on Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill writing-prds -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/writing-prds/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/writing-prds/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill writing-prds -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/writing-prds/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill writing-prds -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/writing-prds/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install RefoundAI/lenny-skills writing-prds
```

2. **Manually: put the files in place**
- File: `.github/skills/writing-prds/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill writing-prds -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/RefoundAI/lenny-skills --path skills/writing-prds
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/writing-prds/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill writing-prds -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/RefoundAI/lenny-skills/tree/HEAD/skills/writing-prds/SKILL.md

## When to use it
- write a problem statement in a few strong sentences
- set success metrics that filter future feature requests
- narrow a fuzzy request into a bounded scope
- audit a PRD draft for brevity and technical awareness
- list non-goals to stop scope creep

## Example prompts
- Help me write a PRD for a new onboarding flow: start with the problem and metrics
- Review my PRD draft for brevity and technical awareness
- Run a shaping session: help me define the project boundaries before development starts

# Writing Product Requirement Documents

Define clear problems and bounded solutions to maximize team velocity and creative output.

Help the user with writing product requirement documents using insights from 14 guests and posts across Lenny's Podcast and Newsletter.

## How to Help

1. **Drafting the core problem** - Assist in articulating a concise problem statement that is agnostic of any specific solution.
2. **Establishing success metrics** - Help define specific, measurable outcomes that will act as a filter for future feature requests.
3. **Defining project boundaries** - Guide the user through narrowing fuzzy requests into a bounded concept using shaping techniques.
4. **Reviewing for clarity** - Audit existing drafts for brevity, readability, and technical awareness to prevent micromanagement.

## Core Principles

### Design for functional prototyping
Jenny Wen: "We used to go off and make this two-year, five-year, 10-year vision even. Now it becomes a vision that's three to six months out, and isn't necessarily creating this beautiful deck, sometimes just creating a prototype that points people in the right direction."

Design should focus on short term functional prototyping rather than static long term planning to keep up with AI driven engineering speeds.

### Shape project boundaries early
Ryan Singer: "What we need to do in a shaping session is we come out with some kind of diagram where engineers, product and design, they're saying, "We understand that." So the first thing is we are not going to start something unless we can see the end from the beginning."

Use high intensity collaborative sessions with design and engineering to create a shared understanding of boundaries before development begins.

### Center documents on the problem
From "Examples and templates of 1-Pagers and PRDs": "Problem-oriented: They crystallize the problem being solved in a few strong sentences—ideally near the top of the document—to focus the brainpower of every teammate in the same direction."

A successful PRD starts with a clearly defined problem and specific success metrics to ensure the team aligns on the why before the what.

### Force clarity through brevity
From "My favorite product management templates": "A reminder of how valuable it is to keep these to one page, at least to start"

Limiting initial project documents to a single page forces the team to stay focused on core goals and helps prevent early complexity.

### Document to move from chaos to clarity
