SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? It turns vague or exaggerated claims about health, science, and technology into a rigorous, source-backed analysis instead of a quick true/false answer, so every conclusion is traceable to real evidence. ## Core Features & Use Cases - Claim Decomposition: Splits a mixed statement into individual verifiable claims and classifies each as empirical, causal, correlational, speculative, or non-scientific. - Evidence Hierarchy and Scoring: Prioritizes systematic reviews, meta-analyses, clinical guidelines, and consensus statements, then rates each claim on a 0-5 confidence scale. - Structured Report: Produces an 11-section report with a verdict, evidence map, caveats, a more precise reformulation, and a source quality list. - Use Case: A user asks "does this supplement really boost memory?" and receives a claim-by-claim analysis citing trials and reviews, flagging marketing exaggeration, and stating what can and cannot be concluded. ## Quick Start Ask the assistant to fact-check a specific claim, for example: "Debunk this claim that drinking celery juice cures chronic disease, and tell me what the science actually says."

Frequently Asked Questions about sagan-scientific-debunker

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

FAQPage Schema
How do I fact-check a health or science claim with AI?▼

State the claim clearly and ask for a scientific analysis. The skill splits it into verifiable claims, searches primary sources like systematic reviews and clinical guidelines, and returns a structured report with a verdict, evidence map, and confidence ratings.

What sources does a scientific claim analysis rely on?▼

It prioritizes systematic reviews, meta-analyses, clinical guidelines, consensus statements, and recognized scientific bodies. News articles, blogs, and anecdotes may add context but never serve as the basis for conclusions.

Does scientific fact-checking require web access?▼

Yes, web access is required when the topic depends on recent research, current news, or shifting scientific consensus. The skill searches for primary and official sources rather than relying on model memory for time-sensitive topics.

Can every claim be answered with true or false?▼

No. The skill explicitly avoids binary verdicts when evidence is mixed, distinguishing absence of evidence from evidence of absence. Claims that are philosophical, normative, or metaphorical are flagged as not scientifically evaluable.

Where is the scientific analysis report saved?▼

The report is delivered directly in the conversation as text, not saved as a file. It follows an 11-section structure including a verdict, evidence map, caveats, reformulation, and a source quality list.
