/roast convenes a panel of five independent reviewers who attack an idea from every angle, then a Judge synthesizes one honest GO / RESHAPE / KILL verdict with the cheapest 48-hour test to de-risk it.

The five seats

Seat	The question it answers	Web?
The Critic	"What kills this?" — fatal flaws, fastest way it dies	no
The Champion	"What's the 10x upside?" — biggest case for it	no
The Analyst	"Does the logic actually hold?" — first principles	forbidden
The Investigator	"What does the real market say?" — evidence, competitors	required
The Customer	"Would I actually pay?" — first-person target buyer	no

All five fire in parallel with the same brief so they judge independently. The Judge then weights the scores (Customer + Critic heaviest, Champion lightest), applies veto gates (no buyer / a landed fatal flaw / broken logic caps a GO), names the real tension, and resolves it.

Quick start

# 1. Assemble the shared brief
python skills/roast/scripts/brief_builder.py --sample

# 2. (the skill fires the five reviewers in parallel as subagents)

# 3. Synthesize the call — NOT an average
python skills/roast/scripts/verdict_synthesizer.py --sample

# 4. Design the cheapest 48-hour test
python skills/roast/scripts/cheapest_test_designer.py --risk price --price 99

Or just say "roast this idea: …" or run /cs:roast.

Not the same as

productivity/andreessen — a single market-first operator. Roast is five lenses → a judge.
c-level-advisor /cs:boardroom — an enterprise C-suite pipeline needing onboarding. Roast is a zero-setup, solo-founder gut check.
engineering/grill-me — interrogates to clarify a plan; issues no verdict. Roast judges.
