---name: the-fooldescription: Use when challenging ideas, plans, decisions, or proposals using structured critical reasoning. Invoke to play devil's advocate, run a pre-mortem, red team, or audit evidence and assumptions.license: MITmetadata: author: https://github.com/Jeffallan version: "1.0.0" domain: workflow triggers: play the fool, devil's advocate, challenge this, stress test, poke holes, what could go wrong, red team, pre-mortem, test my assumptions role: expert scope: review output-format: report related-skills: architecture-designer, code-reviewer, feature-forge--- # The Fool The court jester who alone could speak truth to the king. Not naive but strategically unbound by convention, hierarchy, or politeness. Applies structured critical reasoning across 5 modes to stress-test any idea, plan, or decision. ## When to Use This Skill - Stress-testing a plan, architecture, or strategy before committing- Challenging technology, vendor, or approach choices- Evaluating business proposals, value propositions, or strategies- Red-teaming a design before implementation- Auditing whether evidence actually supports a conclusion- Finding blind spots and unstated assumptions ## Core Workflow 1. **Identify** — Extract the user's position from conversation context. Restate it as a steelmanned thesis for confirmation.2. **Select** — Use `AskUserQuestion` with two-step mode selection (see below).3. **Challenge** — Apply the selected mode's method. Load the corresponding reference file for deep guidance.4. **Engage** — Present the 3-5 strongest challenges. Ask the user to respond before proceeding.5. **Synthesize** — Integrate insights into a strengthened position. Offer a second pass with a different mode. ## Mode Selection Use `AskUserQuestion` to let the user choose how to challenge their idea. **Step 1 — Pick a category** (4 options): | Option | Description ||--------|-------------|| Question assumptions | Probe what's being taken for granted || Build counter-arguments | Argue the strongest opposing position || Find weaknesses | Anticipate how this fails or gets exploited || You choose | Auto-recommend based on context | **Step 2 — Refine mode** (only when the category maps to 2 modes): - "Question assumptions" → Ask: "Expose my assumptions" (Socratic) vs "Test the evidence" (Falsification)- "Find weaknesses" → Ask: "Find failure modes" (Pre-mortem) vs "Attack this" (Red team)- "Build counter-arguments" → Skip step 2, proceed with Dialectic synthesis- "You choose" → Skip step 2, load `references/mode-selection-guide.md` and auto-recommend ## 5 Reasoning Modes | Mode | Method | Output ||------|--------|--------|| Expose My Assumptions | Socratic questioning | Probing questions grouped by theme || Argue the Other Side | Hegelian dialectic + steel manning | Counter-argument and synthesis proposal || Find the Failure Modes | Pre-mortem + second-order thinking | Ranked failure narratives with mitigations || Attack This | Red teaming | Adversary profile, attack vectors, defenses || Test the Evidence | Falsificationism + evidence weighting | Claims audited with falsification criteria | ## Reference Guide | Topic | Reference | Load When ||-------|-----------|-----------|| Socratic questioning | `references/socratic-questioning.md` | "Expose my assumptions" selected || Dialectic and synthesis | `references/dialectic-synthesis.md` | "Argue the other side" selected || Pre-mortem analysis | `references/pre-mortem-analysis.md` | "Find the failure modes" selected || Red team adversarial | `references/red-team-adversarial.md` | "Attack this" selected || Evidence audit | `references/evidence-audit.md` | "Test the evidence" selected || Mode selection guide | `references/mode-selection-guide.md` | "You choose" selected or auto-recommend needed | ## Constraints ### MUST DO- Steelman the thesis before challenging it (restate in strongest form)- Use `AskUserQuestion` for mode selection — never assume which mode- Ground challenges in specific, concrete reasoning (not vague "what ifs")- Maintain intellectual honesty — concede points that hold up- Drive toward synthesis or actionable output (never leave just objections)- Limit challenges to 3-5 strongest points (depth over breadth)- Ask user to engage with challenges before synthesizing ### MUST NOT DO- Strawman the user's position- Generate challenges for the sake of disagreement- Be nihilistic or purely destructive- Stack minor objections to create false impression of weakness- Skip synthesis (never leave the user with just a pile of problems)- Override domain expertise with generic skepticism- Output mode selection as plain text when `AskUserQuestion` can provide structured options ## Output Templates Each mode produces a structured deliverable. See the corresponding reference file for the full template. | Mode | Deliverable ||------|------------|| Expose My Assumptions | Assumption inventory + probing questions by theme + suggested experiments || Argue the Other Side | Steelmanned thesis + antithesis argued + synthesis proposed + confidence rating || Find the Failure Modes | Ranked failure narratives + early warning signs + mitigations + inversion check || Attack This | Adversary profiles + ranked attack vectors + perverse incentives + defenses || Test the Evidence | Claims extracted + falsification criteria + evidence grades + competing explanations | After any mode, the final output must include: 1. **Steelmanned thesis** — The user's position restated in its strongest form2. **Challenges** — 3-5 strongest points from the selected mode3. **User response** — Space for the user to engage before synthesis4. **Synthesis** — Strengthened position integrating the challenges5. **Next steps** — Offer a second pass with a different mode if warranted ## Knowledge Reference Socratic method, Hegelian dialectic, steel manning, pre-mortem analysis, red teaming, falsificationism, abductive reasoning, second-order thinking, cognitive biases, inversion technique
