SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides structured analysis of arguments to strengthen logic, identify gaps, and improve persuasiveness.

Core Features & Use Cases

  • CEW framework guidance: Map claims, evidence, and warrants to ensure logical connections.
  • Evidence quality checks: Evaluate evidence type and sufficiency.
  • Gap detection & counterarguments: Identify missing components and generate steel-man counterarguments.
  • Guided analysis: Step-by-step output for vault content analysis with mapping and improvement suggestions.

Quick Start

Analyze the argument in vault-content.md: identify the main claim, list supporting claims with evidence, and map warrants.

FAQPage Schema
How do I analyze arguments to identify logical gaps and weak reasoning?

Argument analysis systematically maps claims, evidence, and warrants to expose gaps in logic. This Skill uses the Claim-Evidence-Warrant framework to evaluate whether supporting evidence actually justifies the main claim, revealing where reasoning breaks down and how to strengthen it.

What is the Claim-Evidence-Warrant framework and how does it improve my writing?

The CEW framework structures arguments into three components: the claim you're making, evidence supporting it, and the warrant—the logical bridge connecting them. Mapping these reveals missing connections, insufficient evidence, or unstated assumptions, letting you build more persuasive and logically sound arguments.

Can I use argument analysis to evaluate debates, essays, and policy proposals?

Yes. This Skill analyzes arguments across essays, debates, speeches, and policy proposals. It identifies gaps, assesses evidence quality, generates counterarguments, and provides structured recommendations to strengthen reasoning in any persuasive context.

How do I generate counterarguments to test my reasoning?

Steel-manning—constructing the strongest opposing argument—tests your reasoning's resilience. This Skill generates counterarguments by identifying weak points in your evidence and warrants, showing you where alternative interpretations exist and how to address them preemptively.

What's the difference between strong and weak evidence in an argument?

Evidence quality depends on type, relevance, and sufficiency. This Skill evaluates whether your evidence directly supports the claim, relies on credible sources, and provides enough proof. Weak evidence fails one or more criteria, creating gaps the warrant cannot bridge.

Do I need to know formal logic to use structured argument analysis?

No. This Skill provides step-by-step guided analysis that maps arguments visually and identifies gaps without requiring formal training. It translates logical principles into actionable feedback on improving claims, evidence, and reasoning connections.
