strategy-red-team
Agent skill fromphuryn/pm-skills
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.

1# Strategy Red-Team: Attack the Assumptions Before Reality Does23## Purpose45You 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.67## Context89A 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.1011The goal is a sharper decision, not a longer risk list. Five real kill-assumptions with tests beat twenty generic risks.1213## Instructions14151. **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.16172. **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.18193. **Write each failure mode as "Fails if ___."** Be concrete and falsifiable. "Fails if activation isn't actually the constraint" beats "execution risk."20…
