SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Reasoning fails silently through unstated assumptions, missing evidence, or ambiguous terms, and these flaws are invisible from inside your own position. This Skill examines your claim, decision, or conclusion one question at a time to expose where it is weakest before you act on it. ## Core Features & Use Cases - Eight Elements of Reasoning: Probes purpose, question at issue, information, inferences, concepts, assumptions, point of view, and implications as targeted questions. - Nine Intellectual Standards: Audits answers against clarity, accuracy, precision, relevance, depth, breadth, logic, significance, and fairness, naming the standard a weak answer fails. - Entry-Point Routing: Opens with where you are in your reasoning (gathering evidence, testing a conclusion, about to commit) and starts at the element that matches. - Use Case: Before committing to a supplier selected in ten minutes with no objections, use this Skill to surface the assumptions and unexplored points of view the decision rests on. ## Quick Start Ask the assistant to use the critical-thinking skill to poke holes in your conclusion before you act on it.

FAQPage Schema
How do I check my reasoning before making a decision?▼

State your claim or decision and where you are with it, such as gathering evidence or testing a conclusion. The skill asks one question at a time drawn from the eight Elements of Reasoning, following wherever your reasoning is thinnest, usually assumptions or point of view.

What are the Elements of Reasoning in critical thinking?▼

They are eight components present in all reasoning: purpose, question at issue, information, inferences, concepts, assumptions, point of view, and implications. The framework comes from Richard Paul and Linda Elder of the Foundation for Critical Thinking, and each element is examined as a separate question.

Can this skill evaluate text generated by ChatGPT or Claude?▼

No, model output needs different questions because there is no human reasoning route to walk back. The skill hands off to the companion Critical Thinking for GenAI skill, which probes the output itself rather than asking the author.

When should I not use a critical thinking question framework?▼

Skip the full pass when a decision is cheap to reverse, since being wrong costs little. For complex problems that keep recurring with feedback loops, the Systems Thinking skill fits better than element-by-element questioning.

Why does the skill refuse to confirm my conclusion when I ask?▼

It is designed to counter sycophancy, the tendency of language models to agree with users. Before affirming anything, it must find the strongest objection and put that to you first, and it names the request as confirmation-seeking when you ask for agreement.
