## What it does

The skill pits your project against five parallel reviewers. Critic attacks fatal flaws, Champion outlines upside, Analyst checks core logic without web access, Investigator checks competitors via web search, and Customer role-plays willingness to pay. Each persona returns a 1–10 score and their sharpest arguments. Polite hedging is explicitly banned.

Under the hood, three Python standard library scripts process the data without external API calls. First, `brief_builder.py` normalizes your idea into a brief. After subagents evaluate it, `verdict_synthesizer.py` applies deterministic weights, giving veto power to survival flaws and paying objections.

The process finishes with `cheapest_test_designer.py`, which formats a 48-hour experiment to test your riskiest assumption before writing code. Keep in mind that your environment must have Python installed, as these evaluation tools run locally.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add alirezarezvani/claude-skills
```
In the agent chat (not a shell):
```text
/plugin install roast@claude-code-skills
```
This installs the whole roast plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add alirezarezvani/claude-skills --skill roast -a claude-code
```

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

### Codex

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alirezarezvani/claude-skills roast
```

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

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/alirezarezvani/claude-skills --path productivity/roast/skills/roast
```

### Windsurf (Devin Desktop)

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

### 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/alirezarezvani/claude-skills/tree/HEAD/productivity/roast/skills/roast/SKILL.md

## When to use it
- find fatal flaws in a business idea before writing code
- simulate real buyer objections and willingness to pay
- design a cheap 48-hour experiment to de-risk key assumptions
- spot high-leverage growth opportunities through a dedicated champion

## Example prompts
- /roast AI grant application drafting service for non-profits at 99 dollars per month
- /roast Stress-test a developer tool for monitoring background workers
- /roast

description: Use when someone asks to roast an idea, pressure-test or stress-test an idea, validate a business idea, "convene the panel", get a brutal second opinion before building something, or says "/roast". Spins up a 5-angle panel (Critic, Champion, Analyst, Investigator, Customer) that attacks the idea from every angle, then a Judge returns one GO / RESHAPE / KILL verdict with the cheapest test to de-risk it.

# Roast — 5-Angle Idea Panel → One Verdict

> **Portability:** Reasoning-led skill with 3 stdlib Python tools. No external APIs, no LLM calls in
> scripts. Works in Claude Code CLI and Claude.ai web. The panel does the depth; the Judge does the call.

## What this does

Claude's default is to agree with you. `/roast` is the opposite. It convenes a panel of five
independent reviewers — **The Critic, The Champion, The Analyst, The Investigator, and The
Customer** — who tear an idea apart and build it up from every angle, then a Judge synthesizes
everything into one honest verdict. Use it before you sink time and money into building the wrong
thing.

The panel is adversarial on purpose. No reviewer is allowed to hedge or be polite. The point is to
surface what you can't see because you're too close to it.

## Step 1 — Frame the idea

If `$ARGUMENTS` contains the idea, start there. Then ask the user a tight set of clarifying
questions so the panel has real context to work with. Ask only what hasn't already been provided.
Keep it to 3-4 questions max, in one batch:

1. **The idea** in one or two sentences (what it is, what it does).
2. **Who it's for** and **how it makes money** (the buyer + the price/model).
3. **Your edge** — relevant skills, audience, or assets you already have.
4. **Constraints** — budget, timeline, how fast you need first dollar.

If the user says "just run it" or gives you enough already, skip the questions and proceed. Don't
over-interrogate. One round, then run the panel.

Assemble the brief with `scripts/brief_builder.py` — it normalizes the four load-bearing inputs into
one paragraph and tells you if anything critical is still missing before you spend five subagents:

```bash
python scripts/brief_builder.py \
  --idea "AI that drafts grant applications for small nonprofits from a 10-min intake call" \
  --who "1-3 person nonprofits with no grant writer" \
  --money "$99/mo SaaS" --edge "I ran a nonprofit for 8 years" \
  --constraints "bootstrapped, first dollar in 30 days"
```

Paste the resulting brief verbatim into every panelist's prompt, so all five judge the same thing.

## Step 2 — Run the 5-angle panel (5 reviewers, in parallel)

Spin up **all five reviewers in parallel in a single message** (one Task call each,
