Test system behavior under extreme load conditions to identify breaking points, capacity limits, and failure modes. Use for stress test, capacity testing, breaking point analysis, spike test, and system limits validation.
Stress-test plans, proposals, and strategies. Use for pre-mortems, assumption audits, risk registers, evaluating business ideas, identifying failure modes, or when you need devil's advocate analysis before committing resources.
Devil's Advocate stress-testing for code, architecture, PRs, and decisions. Surfaces hidden flaws through structured adversarial analysis with metacognitive depth. Use for high-stakes review, stress-testing choices, or when the user wants problems found deliberately. NOT for routine code review (use engineering:code-review). Triggers on "스트레스 테스트", "stress test", "devil's advocate", "반론", "이거 괜찮아", "문제 없을까", "깊은 리뷰", "critical review", "adversarial".
Expert guidance for systematic backtesting of trading strategies. Use when developing, testing, stress-testing, or validating quantitative trading strategies. Covers "beating ideas to death" methodology, parameter robustness testing, slippage modeling, bias prevention, and interpreting backtest results. Applicable when user asks about backtesting, strategy validation, robustness testing, avoiding overfitting, or systematic trading development.
Single-critic adversarial stress test of a known artifact — a PR, draft, spec, plan, code file, or argument. The reviewer actively tries to break it: edge cases, hidden assumptions, failure modes, logical inconsistencies, security gaps, scalability cliffs, surprising user behavior, counter-examples. Distinct from /council-review, which is for OPEN questions and decisions; this skill is for stress-testing a finished thing. Use when: 'adversarial review', 'red team this', 'find what is wrong', 'tell me why this is wrong', 'pre-mortem this', 'attack this', 'stress test', 'devil's advocate', 'try to break this', or before shipping any artifact where a missed edge case is expensive.
Review a web interface, a UI diff or a single component and return ranked, fixable findings. Use for design critique, UI audits, accessibility checks, reviewing a branch or PR for interface impact, stress-testing one component across states and sizes, or explaining how an observed interface or animation is built.
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.
Build quick IRR/MOIC sensitivity tables for PE deal evaluation. Models returns across entry multiple, leverage, exit multiple, growth, and hold period scenarios. Use when sizing up a deal, stress-testing assumptions, or preparing IC returns exhibits. Triggers on "returns analysis", "IRR sensitivity", "MOIC table", "what's the return at", "model the returns", or "back of the envelope".
Run a pre-mortem risk analysis on a PRD or launch plan. Categorizes risks as Tigers (real problems), Paper Tigers (overblown concerns), and Elephants (unspoken worries), then classifies as launch-blocking, fast-follow, or track. Use when preparing for launch, stress-testing a product plan, or identifying what could go wrong.
Help the user shape technical blog posts, website articles, devlogs, essays, or long-form drafts without writing the full post for them. Use this whenever the user shares rough notes, a brain dump, unordered ideas, bullet points, or half-written sections, or asks for help turning notes into an outline, finding the angle, sharpening the hook or thesis, improving structure, clarifying the argument, tightening flow, stress-testing the payoff, or making a technical piece more engaging while preserving their voice. Use it even if the user does not explicitly ask for a writing guide, as long as they need help organizing and developing a post rather than having it ghostwritten. Guide with organization, critique, focused questions, and tiny example lines only; do not write the final article.
Produces a one-page lean canvas across nine interlocking blocks (problem, customer, UVP, solution, channels, revenue, cost, metrics, unfair advantage) with optional inline HTML and SVG visual rendering. Use when framing a new product thesis, stress-testing an existing strategy, comparing strategic options side-by-side, or aligning a team on business-model assumptions. Works as a strategic hub that cross-links to deeper PM skills without duplicating them.
Calibrated grilling session for stress-testing a plan, design, idea, or decision. First assesses the user's topic knowledge, confidence, and desired pressure level, then asks one question at a time with recommended answers. Use when user says "grill me", "stress-test this", "challenge my plan", "interview me", or wants a plan probed without being overwhelmed.
