Evaluates one short defeasible argument by classifying it as a stereotyped reasoning scheme (appeal to expert opinion, analogy, sign, cause to effect, consequences, popular practice, slippery slope, practical reasoning), instantiating the scheme's premise slots to expose its implicit premises, then putting that scheme's keyed critical questions to it and rendering a presumption verdict that stands or falls by burden of proof. Produces a scheme critique sheet. Use when a single presumptive…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- thinking-framework-skills | https://github.com/product-on-purpose/thinking-framework-skills | Apache-2.0 --> # Argumentation Schemes with Critical Questions Most everyday arguments are not deductive proofs. They are defeasible, presumptive moves: an expert says X, so presumably X; this case is like that case, so presumably the same verdict; doing A leads to bad consequence B, so presumably do not do A. Douglas Walton's insight is that these arguments come in a finite set of stereotyped patterns, that each pattern is legitimate (not a fallacy) when its conditions hold, and that each pattern has its own characteristic ways of failing. The durable move is **classify-then-probe-with-keyed-defeaters**: first identify which stereotyped scheme an argument instantiates, then interrogate it with the standard critical questions keyed to that scheme. Two things make this more than generic objection-raising. The defeaters are retrieved, not improvised - each scheme's question set encodes the accumulated knowledge of how that specific pattern fails, so coverage of the standard vulnerabilities does not depend on what occurs to the evaluator in the moment. And the semantics are presumptive …

How to install
mdr add product-on-purpose/thinking-framework-skills/think-walton-argumentation-schemes@sha256:9c16cf5f465e9af7The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
