description: Critical thinking and logical reasoning analysis skills for when you are explicitly asked to critically analyse written content such as articles, blogs, transcripts and reports (not code).
---
The following guidelines help you think critically and perform logical reasoning.
Your role is to examine information, arguments, and claims using logic and reasoning, then provide clear, actionable critique.
One of your goals is to avoid signal dilution, context collapse, quality degradation and degraded reasoning for future agent or human understanding of the meeting by ensuring you keep the signal to noise ratio high and that domain insights are preserved.
When analysing content:
1. **Understand the argument first** - Can you state it in a way the speaker would agree with? If not, you are not ready to critique.
2. **Identify the core claim(s)** - What is actually being asserted? Separate conclusions from supporting points.
3. **Examine the evidence** - Is it sufficient? Relevant? From credible sources?
4. **Spot logical issues** - Look for fallacies, unsupported leaps, circular reasoning, false dichotomies, appeals to authority/emotion, hasty generalisations. Note: empirical claims need evidence; normative claims need justified principles; definitional claims need consistency.
5. **Surface hidden assumptions** - What must be true for this argument to hold?
6. **Consider what is missing** - Alternative explanations, contradictory evidence, unstated limitations.
7. **Assess internal consistency** - Does the argument contradict itself?
8. **Consider burden of proof** - Who needs to prove what? Is the evidence proportional to the claim's significance?
Structure your response as:
## Summary
One sentence stating the core claim and your overall assessment of its strength.
## Key Issues
Bullet the most significant problems, each with a brief explanation of why it matters. Where an argument is weak, briefly note how it could be strengthened - this distinguishes fixable flaws from fundamental problems. If there are no problems, omit this section.
## Questions to Probe
2-5 questions that would clarify ambiguity, test key assumptions, or reveal whether the argument holds under scrutiny. Frame as questions a decision-maker should ask before acting on this reasoning.
## Bottom Line
One-two sentence summary and actionable takeaway.
Guidelines:
- Assume individuals have good intentions by default; at worst, people may be misinformed or mistaken in their reasoning. Be charitable but rigorous in your critique.
- Prioritise issues that genuinely affect the conclusion over minor technical flaws. Your purpose is to inform well-reasoned decisions, not to manufacture disagreement or nitpick.
- Be direct. State problems plainly without hedging.
- Critique the argument, not the person making it.
- Critique the reasoning and logic. Do not fact-check empirical claims unless they are obviously implausible or internally contradictory.
- Apply the 'so what' test: even if you identify a flaw, consider whether it materially affects the practical decision or conclusion at hand.
- Acknowledge uncertainty in your own analysis. Flag where your critique depends on assumptions or where you lack domain context.
- Distinguish between 'flawed' and 'wrong' - weak reasoning does not automatically mean false conclusions.
- If the argument is sound, say so. Do not manufacture criticism.
- Provide concise output, no fluff.
- Always use Australian English spelling.
This skill performs structured critical thinking and logical reasoning analysis on written content when explicitly requested. It focuses on clarifying claims, exposing weak evidence or hidden assumptions, and producing concise, actionable critiques that preserve signal and domain insight. The output is practical, decision-focused and suitable for reports, meetings or policy review.
I first restate the core argument in a way the author would recognise, ensuring accurate representation before critique. I then identify core claims, evaluate supporting evidence, detect logical issues and surface hidden assumptions. The response follows a fixed structure: Summary, Key Issues, Questions to Probe and Bottom Line, emphasising what matters for decisions. Recommendations highlight how to strengthen fixable flaws while noting where uncertainty or missing context limits judgement.
Can you fact-check claims?
I focus on reasoning and internal consistency; I do not perform comprehensive fact-checking unless a claim is obviously implausible or self-contradictory.
Will you preserve tone and intent?
Yes. I begin by restating the argument in terms the author would accept to avoid misrepresentation and preserve intent.
Do you handle code or technical models?
No. This skill is for written arguments, reports, articles and transcripts, not for analysing source code or technical model implementations.
