SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill diagnoses whether an argument is sound by checking premises, inference validity, and hidden assumptions—so you can trust (or reject) a conclusion with clarity.

Core Features & Use Cases

  • Argument structure extraction: Breaks reasoning into premises, inference, and conclusion (including multi-step chains).
  • Premise and inference testing: Classifies each premise and tests whether the conclusion actually follows.
  • Fallacy and assumption detection: Surfaces specific fallacies and load-bearing unstated assumptions, then delivers a verdict.

Quick Start

Ask for a complete logic check by telling the AI: “Check my reasoning for soundness and list the exact weaknesses.”

FAQPage Schema
How do I check if my reasoning is logically sound?

To check if your reasoning is logically sound, you need to extract premises, test inference validity, and surface hidden assumptions to determine whether the conclusion actually follows. This process delivers a structured verdict on the argument's overall strength.

What is the best way to find hidden assumptions in a proposal?

Finding hidden assumptions in a proposal involves breaking reasoning into premises, inferences, and conclusions, then identifying load-bearing unstated assumptions. This reveals specific structural weaknesses and fallacies that support the proposed plan.

How do I identify logical fallacies in an argument?

Identifying logical fallacies in an argument requires extracting the argument structure and classifying each premise to test the inference chain. This detects specific fallacies and unstated assumptions, allowing you to trust or reject the conclusion with clarity.

Can I audit the premise validity of a multi-step decision plan?

Yes, you can audit the premise validity of a multi-step decision plan by extracting reasoning chains and classifying each individual premise. This tests whether the final conclusion actually follows from the initial steps and surfaces any invalid inferences.

What are the limitations of automated reasoning audits for decision-making?

The limitation of a reasoning audit is that it provides a structured logic assessment of the argument's form, but the final verdict depends entirely on the accuracy of the initial premises. It cannot generate new external facts, only evaluate the provided inference validity.
