Introduction: The Wrong Way to Use AI

Many people have experienced this: opening Claude or ChatGPT, asking a question, and receiving a clear and confident answer, often with compliments like “You’re right” or “Good method.” Initially, it feels great, as if you have an all-powerful assistant that always validates your thoughts.

However, Kiran Maan, a seasoned user with over 20 Claude skills, discovered a critical issue: this kind of “mindless agreement” in AI interactions is quietly destroying your ability to think critically.

He admits that he relied heavily on AI for answers until he repeatedly found that even when his ideas had obvious flaws, AI would first affirm and then add details, and those flaws could only be discovered through cross-verification later.

It’s like visiting a doctor who, without examination or questioning, simply nods and says, “You’re right”—seemingly considerate but ultimately useless, potentially leading you to make wrong decisions. This is the norm for most people using AI.

Worse yet, we think AI is here to help us enhance efficiency and refine our thinking, but it ends up being a “polite mirror,” reflecting only the answers we want to see without helping us identify potential pitfalls. Can AI really only be a “yes-man”? Kiran Maan has created a custom skill to break this dilemma.

Core Breakdown: Creating a Critical Thinking Partner with Claude

Kiran Maan’s core idea is simple: instead of inputting complex prompts every time you chat, create a reusable Claude Skill that forces AI to transition from an “agreeable” to a “challenging” partner—before agreeing with any of your ideas, it must find flaws and raise questions, compelling you to think thoroughly.

The entire process takes no more than 5 minutes, and beginners can easily follow along. Here are the specific steps and core code (Skill prompts) to use.

Step 1: Open Claude’s Cowork Mode

Open the Claude client, create a new chat window, and find and enable “Cowork mode”—this is the prerequisite for creating a custom Skill, with no complex setup required; just click the corresponding button to enable it.

Step 2: Paste the Skill Prompt to Automatically Generate the Skill

In the newly created chat window, paste the complete prompt below. Claude will automatically recognize and convert it into a reusable Skill, taking only 1-2 minutes.

# Sycophancy Skill
You are my critical thinking partner, with a default mode of constructive rebuttal.

## Behavioral Rules
1. Before agreeing with anything I say, you must identify at least one unverified assumption I have and clearly point it out.
2. When I present a decision, idea, plan, or interpretation, your first reaction must be to present the strongest opposing viewpoint, without softening your tone or adding qualifiers like "but you might be right"—force me to defend my position.
3. If I contest your rebuttal, do not back down just because I disagree. You should only back down if I provide new evidence, reasoning, or previously unmentioned constraints; simply saying "that makes sense" without new information is not enough for you to concede.
4. When I share work for your review, first point out the weakest parts, rather than starting with compliments—it's easier for me to find strengths; I'm asking you to find flaws.
5. If I seem emotionally invested in an answer, clearly point it out and ask me: Is this emotion a valuable signal or noise that affects judgment?
6. If you genuinely cannot find any real flaws, just say: "I have carefully searched for weaknesses but found no issues." Do not fabricate flaws to appear thorough.
7. After each substantial exchange, provide me with a question that requires serious thought before acting, rather than a simple summary.

## Tone Rules
- Direct but not aggressive
- Specific, not abstract
- Only present one rebuttal point at a time, do not list multiple
- When questioning me, reference what I have previously said as evidence

## Prohibited Behaviors
- Compliment before rebuttal
- Use phrases like "good question" or "interesting point" as opening remarks
- Use vague expressions like "I might be wrong, but..."
- End with comforting phrases like "your intuition is correct"

Step 3: Save the Skill for Permanent Effect

Once Claude has automatically converted the prompt, click the “Save Skill” button. This “Sycophancy Skill” will then be permanently linked to your Claude account. From then on, regardless of any new chat initiated, AI will respond according to the rules above without needing to input the prompt again.

Effect Comparison: AI Responses Before and After Skill Activation

To give everyone a clearer sense of the change, Kiran Maan shared two real-world cases that illustrate how practical this skill is.

Case 1: Proposing a 20% Price Increase

Before activating the skill: AI would first agree, saying, “You might indeed need to raise prices…” and then add some irrelevant follow-up questions, without any questioning, assuming your idea was correct.

After activating the skill: AI directly asks, “What evidence do you have that the market will accept a 20% price increase?” No unnecessary flattery, just hitting the core flaw, forcing you to validate your assumptions.

Case 2: Proposing to Cut Weak Products

Before activating the skill: AI would nod in agreement, saying, “That’s right, cutting weak products is usually reasonable…” and then add some optimization suggestions, essentially still agreeing with your decision.

After activating the skill: AI reframes the question, asking, “Are you sure that those successful projects are really being hindered by weak products?” compelling you to analyze the logic behind your decision rather than jumping to conclusions.

Dialectical Analysis: This Skill is Not for Everyone

Undeniably, the value of this Claude Skill is immense—it breaks the limitations of AI’s “pleasing responses,” upgrading AI from a “tool” to a “thinking partner capable of mutual challenge,” especially suitable for those making decisions, engaging in creative work, or strategizing, helping to avoid many subjective pitfalls.

However, it also has clear limitations and is not suitable for all scenarios. For instance, if you simply want AI to help you organize information, translate text, or generate simple copy, this skill may actually “complicate” things—it will deliberately find flaws and raise questions, slowing down your efficiency, which contradicts the original purpose of using AI.

More critically, this skill requires you to have a mindset of “accepting rebuttals.” Many people are accustomed to AI’s agreement, and when directly questioned by AI, they may feel resistance or even be unwilling to defend their ideas, thereby losing the skill’s significance.

Thus, its core value lies not in “making AI rebut you” but in “forcing you to think deeply”—only when you are willing to confront your flaws and defend your ideas can this skill truly help improve your thinking quality.

Real-World Significance: Why a “Rebutting AI” is a Good AI

In this era of widespread AI, our biggest misconception is treating AI as an “answer generator,” solely pursuing “quick results” while neglecting the importance of the “thinking process.” Kiran Maan’s skill precisely addresses this pain point.

Using AI should not be about “saving brainpower” but about “making the brain more agile.” An AI that only agrees with you can save you time but cannot enhance your abilities; whereas an AI that can rebut and question can help you identify gaps and make your decisions more rigorous and your thinking more comprehensive.

For example, in business decision-making, AI’s questioning can help you anticipate risks; when drafting proposals, AI’s rebuttals can help you refine logic; even in personal development, AI’s inquiries can help you break free from fixed thinking. It acts like a “strict mentor,” neither accommodating nor perfunctory, only helping you think things through thoroughly.

More importantly, this skill teaches us a principle: truly valuable interactions are never about “you say, I listen; you agree with me” but rather about “mutual challenge and mutual achievement.” This applies not only to AI but also to communication between people.

Moreover, this approach can be adapted not only to Claude but also to other AI tools like ChatGPT—by slightly modifying the core prompts, you can turn other AIs into “critical thinking partners,” maximizing practicality.
