## What it does

The skill organizes technical and product decision-making using insights from 14 guests across Lenny's Podcast and Newsletter. When facing competing priorities, the assistant applies structured frameworks like Naomi Gleit's Traffic Light Decision Matrix, Nicole Forsgren's Weighted Spreadsheet, or Austin Hay's Build AND Buy model.

It focuses on surfacing technical rabbit holes before teams commit to high-fidelity designs. The skill flags common reasoning traps: the myth of adding just one more engineer, binary build-vs-buy debates, and underestimating the failure rate of radical redesigns. It gives teams a structured way to defend roadmap choices.

Detailed templates and decision documents reside in `references/artifacts.md`. Without local repository context, the agent only provides high-level structures.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install RefoundAI/lenny-skills evaluating-trade-offs
```

2. **Manually: put the files in place**
- File: `.github/skills/evaluating-trade-offs/SKILL.md`

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/RefoundAI/lenny-skills --path skills/evaluating-trade-offs
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill evaluating-trade-offs -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/evaluating-trade-offs/SKILL.md

## When to use it
- resolve build versus buy software dilemmas with a hybrid approach
- prepare an SCQA document to communicate tradeoffs to senior leaders
- calculate the business risk and cost of inaction on technical debt
- evaluate competing options with a traffic light decision matrix

## Example prompts
- Help us evaluate whether to build an internal analytics engine or use the Build AND Buy framework.
- Draft an SCQA tradeoff document for leadership explaining why we must pause feature work for technical debt.
- Run our infrastructure migration options through the Traffic Light Decision Matrix.

# Evaluating Trade-Offs

Master the art of weighing competing options to maximize long-term impact and team velocity.

Help the user with evaluating trade-offs using insights from 14 guests and posts across Lenny's Podcast and Newsletter.

## How to Help

1. **Framework Selection** - Match the right decision template to the specific tradeoff scenario you are facing.
2. **ROI Calculation** - Assist in modeling the long-term business impact versus the operational costs of a proposed path.
3. **Stakeholder Communication** - Refine how you present tradeoffs to leadership to ensure they see the hidden costs of saying yes.
4. **Bias Detection** - Identify common traps like the sunk cost fallacy or the just one more engineer myth in your current thinking.

## Core Principles

### Surface rabbit holes during shaping
Ryan Singer: "I often use this analogy of if you're doing a home renovation, you can have the most beautiful rendering of the new bedroom and we're going to have these lamps on the side of the bed that are coming out from the wall. But if you haven't checked if there's electricity in that wall there or not, it's going to drastically change the cost and the time and everything."

Involve senior engineers early to identify technical complexities and infrastructure constraints before committing the team to a high-fidelity design.

### Quantify the risk of inaction
From "This Week #13: Balancing outcome-thinking with design and technical requirements ⚖️": "To answer your question about how we balanced this outcome-thinking with engineering and design needs (which often don’t directly drive that outcome), it’s simple — extend your outcome thinking further out into the future. How much would this work benefit your outcome (e.g. growth, quality, retention) 1+ years out? What happens if you don’t do it? What are the chances of it being successful?"

Evaluate major technical or design investments by comparing the impact of doing the work now versus the cost and risk of doing nothing.

### Use SaaS for foundational needs
Austin Hay: "That's how you actually have a lot of velocity is thinking about not just build versus buy. It's build and buy now. So, you buy the tool to get 90% of the way there and then you build the cool thing on top with the other 10%. And so that architecting decision usually falls on this person."
