SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you challenge ideas, plans, and proposals before you commit by uncovering weaknesses, blind spots, and weak evidence.

Core Features & Use Cases

  • Steelmanned positioning: Restates your proposal in its strongest form to ensure critique targets the real argument.
  • Mode-based adversarial critique: Runs one of five critical modes to probe assumptions, counter-argue, find failure modes, red-team vulnerabilities, or test evidence.
  • Cognitive-bias scanning with grounded challenges: Flags common reasoning patterns that can distort judgment and weaves them into the critique.
  • Strengthened synthesis after user engagement: Produces a refined position with explicit trade-offs and a confidence rating, after you respond to the challenges.

Quick Start

Ask the Skill to challenge your current plan as devil’s advocate and do not synthesize until you respond to the 3-5 strongest critiques.

Frequently Asked Questions about the-fool

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
What is a pre-mortem analysis and how does it help stress-test decisions?

Red-teaming assumptions requires steelmanning your proposal first, then selecting a specific reasoning mode like assumption testing or evidence grading to probe for cognitive biases, failure modes, and vulnerabilities before you commit to a decision.

How do I run a devil's advocate critique on my project proposal?

To run a devil's advocate critique, present your proposal to be steelmanned, select a critique mode like assumption testing or pre-mortem, review the generated challenges and cognitive bias flags, then respond to the critiques to receive a refined synthesis with explicit trade-offs and a confidence rating.

Can I use this adversarial stress testing for any domain or proposal type?

Adversarial stress testing applies to proposals in any domain. The critique workflow operates by steelmanning the input, scanning for cognitive biases, and running mode-specific reference-driven challenges regardless of the specific industry or subject matter.

What is the difference between a pre-mortem and evidence grading in risk analysis?

A pre-mortem imagines a future failure to identify root causes and vulnerabilities, while evidence grading evaluates the strength and falsifiability of the data supporting your proposal. Both are selectable reasoning modes used to audit decisions before commitment.

When should I not use a devil's advocate workflow for decision auditing?

Avoid using a devil's advocate workflow when a decision is trivial, fully reversible, or when you lack the necessary evidence to engage with the generated critiques, as the synthesis phase requires you to actively respond to challenges to produce a refined position.
