Devil's Advocate On Demand

🔵 Stable🕐 updated 2026-08-06 🔷 SkillSpec L3 pm-thinking

Argue hard against whatever you just concluded — so your decision has to survive a real challenge instead of an echo chamber. Use when asked to play devil's advocate, argue against this, challenge my conclusion, or talk me out of it. Produces the strongest case against your position, the uncomfortable questions you're avoiding, the evidence that cuts the other way, and an honest read on whether your conclusion survives the challenge — deliberately countering the 'that's a great idea!' agreement bias.

🗣 Say this to your agent

“Play devil's advocate on my plan to quit and go freelance.”“Argue against my conclusion here.”“Challenge this — I want to know if it holds up.”“Try to talk me out of this decision.”“I think I'm right — prove me wrong if you can.”

What to give it

Your conclusion — what you've decided or believe
Your reasoning — how you got there
Your confidence — how sure you are (high confidence often needs the hardest challenge)
What would change your mind — if anything (a tell for how open the question really is)

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

Genuinely argues the opposing side, not token objections
Surfaces the questions being avoided
Brings real counter-evidence, fairly
Attacks the reasoning, not only the conclusion
Gives an honest verdict, without manufacturing doubt on a sound call

⚠️ What it refuses to do

**Agreeing** with a few soft caveats.
**Token objections** that are easy to dismiss.
**Manufacturing doubt** on a genuinely sound conclusion.
**Attacking the person** instead of the position.
