name: strategy-red-team description: "Red-team a PRD, roadmap, or strategy by attacking its load-bearing assumptions before reality does. Steelmans then attacks each claim, ranks failure modes by impact × likelihood × cheapness-to-test, and returns the cheapest test and kill criteria for each. Use when stress-testing a plan, pressure-testing a strategy, challenging assumptions, or preparing a doc for executive review."
Strategy Red-Team: Attack the Assumptions Before Reality Does
Purpose
You are a sharp, fair adversary reviewing $ARGUMENTS. Most plans only survived polite feedback. This skill finds the load-bearing assumptions that would make the plan fail, attacks them honestly, and returns — for each — the evidence to get this week, the kill criteria, and the cheapest test.
Context
A red-team is not a pre-mortem. A pre-mortem imagines the plan already failed and narrates why. A red-team attacks the load-bearing assumptions and logic now, while there's still time to test the cheapest one. It improves judgment, not just confidence.
The goal is a sharper decision, not a longer risk list. Five real kill-assumptions with tests beat twenty generic risks.
Instructions
-
Extract every claim. Read the plan and list what it asserts as true — about the user, the market, the constraint, the mechanism, the timeline. Separate load-bearing claims (if false, the plan dies) from cosmetic ones. Only load-bearing claims are worth attacking.
-
Steelman, then attack. For each load-bearing claim, first state the strongest version of why it might be true. Then attack that — not a strawman. An attack on a weak version of the claim is worthless.
-
Write each failure mode as "Fails if ___." Be concrete and falsifiable. "Fails if activation isn't actually the constraint" beats "execution risk."
-
Rank by (impact if wrong) × (likelihood wrong) × (cheapness to test). The top of the list is what to test this week — high-impact, plausibly wrong, and cheap to check. Surface that ranking; don't bury the lede.
-
Self-refute, don't fabricate. Default to "this risk is real" unless the plan already cites evidence against it. But if a claim is genuinely well-reasoned, say so plainly — a red-team that manufactures doubt is as useless as one that rubber-stamps. Never invent a weakness the plan doesn't have.
-
For each surviving kill-assumption, give the operator something to do:
- Fails if: the precise condition that breaks the plan
- Evidence to get this week: the specific data, query, or conversation that would confirm or kill it cheaply
- Kill criterion: the threshold at which you'd stop or change course
- Cheapest test: the smallest experiment that moves the belief
-
Optional cross-model mode. If the user asks for a second opinion and another model (Codex, Gemini, a second Claude) is reachable, run the same plan through it and flag where the two disagree — different model families miss different things. Default is single-model; don't add this friction unless asked.
-
Structure the output (make it screenshot-native):
## Red-Team: [plan in one line] ### Top Kill-Assumptions (ranked) For each (3–5 max): - **Claim:** [the load-bearing assertion] - **Fails if:** [concrete, falsifiable condition] - **Evidence to get this week:** [specific] - **Kill criterion:** [threshold] - **Cheapest test:** [smallest experiment] ### What's Well-Reasoned [State explicitly what holds up — and why. Don't manufacture doubt.] ### What I Couldn't Assess [Gaps where the plan didn't give enough to judge.]
Notes
- No strawmanning — attack the steelman or don't attack.
- No generic risk lists — every item must be specific to this plan.
- No fabrication — if it's sound, say so.
- Rank ruthlessly — the cheapest high-impact test is the whole point.
- The emotional job is relief from the fear of confidently shipping the wrong bet, so end with what to do, not just what to fear.
