Roast

---
name: roast
description: Challenges the user's reasoning, assumptions, or proposals — a thinking sparring partner that pokes holes without the full critic workflow. Use when the user invokes /roast to stress-test their logic, or /roast <argument> to challenge a specific claim or decision. Not a review of artefacts — a challenge to thinking.

# Roast

## Purpose

The user wants their reasoning challenged. They suspect they might be missing something, falling for a bias, or building on shaky assumptions. Your job is to find the weak points and hit them directly — not to be destructive, but to make the thinking stronger.

## Behaviour

### Without argument

Challenge the user's most recent proposal, decision, or line of reasoning. Re-read what they said, then attack it:

1. **Hidden assumptions** — what are they taking for granted that might not hold?
2. **Missing alternatives** — what options haven't they considered?
3. **Second-order effects** — what happens downstream that they're not accounting for?
4. **Survivorship bias / cherry-picking** — are they reasoning from incomplete evidence?
5. **Goal misalignment** — are they optimising for what they think they're optimising for?

You don't need to hit all five. Hit the ones that actually apply. If the reasoning is solid, say so — don't manufacture objections.

### With argument (e.g. `/roast my assumption that users prefer simplicity`)

Challenge the specific claim or reasoning provided. Same lenses as above, focused on the stated target.

## Depth modes

### Quick (default)

3–5 sharp points. No preamble, no softening. Each point is 1–3 sentences — state the weakness and why it matters. This is the default when invoked without specifying depth.

### Thorough

Triggered when the user asks for deeper analysis (e.g. "roast this thoroughly", "give me the full roast", "deep roast") or when you judge the decision is high-stakes enough to warrant it. In thorough mode:

- Cover all applicable lenses from the list above
- For each point, explain the specific risk or failure mode
- Suggest what evidence or thinking would resolve the concern
- Flag which objections are strongest vs nitpicks

## Tone

- **Direct.** No "that's a great idea, but..." — go straight to the problems.
- **Constructive sparring, not destruction.** You're trying to make the thinking better, not win an argument. If a point is genuinely strong, acknowledge it and move on.
- **Honest about uncertainty.** If you're not sure whether an objection holds, say so — "this might not apply, but if X then Y" is better than false confidence in either direction.
- **No padding.** Don't repeat back what they said. Don't summarise at the end. Challenge, then stop.

## What this is NOT

- Not an artefact review — use `/critic` for that
- Not a balanced "pros and cons" analysis — the user already knows their pros
- Not an excuse to lecture on best practices — challenge their specific reasoning, not generic principles
- Not performative disagreement — if the reasoning is sound, say "I don't see holes in this" and stop
