Critical Thinking

Analyze arguments, detect biases, evaluate claims, and improve reasoning. Use when asked to fact-check, identify logical fallacies, evaluate arguments, analyze predictions, find root causes, or think adversarially about plans. Triggers include "evaluate this argument", "logical fallacies", "fact check", "analyze the claims", "identify biases", "devil's advocate", "red team this", "root cause".

Critical Thinking

Rigorous analysis of arguments, claims, and reasoning.

Pattern Selection

Intent	Pattern	When to Use
Claim evaluation	`analyze_claims`	Assess truth claims with evidence
Prediction analysis	`extract_predictions`	Identify and assess predictions
Extraordinary claims	`extract_extraordinary_claims`	Claims contradicting consensus

Error analysis	`analyze_mistakes`	Learn from past errors
Problem finding	`extract_primary_problem`	Root cause identification
Solution analysis	`extract_primary_solution`	Evaluate proposed solutions
Adversarial thinking	`t_red_team_thinking`	Find weaknesses in plans
Decision upgrade	`create_upgrade_pack`	Improve decision-making
Novel insights	`extract_alpha`	Most surprising/novel ideas
Thought organization	`create_idea_compass`	Structure complex ideas

Output Guidelines

Always distinguish claims from evidence
Rate confidence levels explicitly
Identify logical fallacies by name
Present steelman versions of arguments before critiquing
Note when evidence is insufficient to conclude
Acknowledge uncertainty and areas of genuine disagreement
