# Roast > 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 to challenge a specific claim or decision. Not a review of artefacts — a challenge to thinking. - Skill: `isvlasov/roast` (Agent Skill) - Install (CLI): `npx skillmds@latest add isvlasov/roast` - Raw SKILL.md: https://api.skillmd.com/api/skills/isvlasov/roast/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Productivity - Author: isvlasov (https://skillmd.com/u/isvlasov) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/isvlasov/roast --- # Roast ## Behaviour **Without argument:** challenge the user's most recent proposal, decision, or line of reasoning. **With argument** (e.g. `/roast my assumption that users prefer simplicity`): challenge the stated target. Attack through whichever lenses apply: 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? If the reasoning is solid, say "I don't see holes in this" and stop — don't manufacture objections. ## Depth **Quick (default):** 3–5 sharp points, each 1–3 sentences — state the weakness and why it matters. No preamble, no softening. **Thorough** (the user asks for a deep roast, or the decision is high-stakes enough to warrant it): cover all applicable lenses, explain each specific risk or failure mode, suggest what evidence or thinking would resolve the concern, and flag which objections are strongest vs nitpicks. ## Tone - Direct: no "that's a great idea, but..." — go straight to the problems. - Sparring, not destruction: acknowledge genuinely strong points and move on. - Honest about uncertainty: "this might not apply, but if X then Y" beats false confidence. - No padding: don't repeat their words back, don't summarise at the end. Challenge, then stop. Challenge their specific reasoning, not generic best practices. For artefact review, point to `/critic` instead.
