SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill identifies and evaluates causal relationships within a given dataset or body of evidence, moving beyond simple correlations by applying established causal inference frameworks (e.g., Bradford Hill criteria, counterfactual reasoning) to assess whether one variable (the cause) is responsible for changes in another (the effect).

Core Features & Use Cases

  • Identify candidate cause-effect relationships in the provided context.
  • Classify evidence into a strict hierarchy of study types (RCT, observational, mechanistic, expert_opinion) and evaluate its methodological rigor.
  • Document confounding variables, reverse causality, selection bias, or other threats to internal validity.
  • Produce a structured JSON output that clearly separates robust causal conclusions from mere associations and highlights critical gaps in evidence.

Quick Start

Analyze a dataset or narrative text to extract causal claims and produce a JSON report.

Frequently Asked Questions about causal_analysis

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

FAQPage Schema
How do I distinguish causation from correlation in observational studies?

Yes, you can assess randomized controlled trial results by processing the experimental data or narrative text through this skill. It classifies the evidence type as RCT within a strict hierarchy, evaluates methodological rigor, and outputs a structured JSON object separating robust causal conclusions from mere associations.

What is the best way to identify confounding variables and selection bias in data?

To evaluate causal claims from literature reviews, input the narrative text to extract and classify cause-and-effect relationships. The skill applies a strict taxonomy of evidence types including mechanistic and expert opinion, producing a structured JSON report that explicitly separates robust causal conclusions from associations.

Can I use causal inference frameworks to assess strength of evidence in text?

Yes, you can use causal inference frameworks to assess the strength of evidence in text by applying counterfactual reasoning to the claims. The skill outputs a structured JSON object detailing claims, evidence type, confounders noted, and an explicit strength assessment based on the evidence hierarchy.

What are the limitations of causal analysis for mechanistic and expert opinion evidence?

The limitation of causal analysis for mechanistic and expert opinion evidence is that these sit lower in the strict evidence hierarchy than RCTs or observational studies. The skill explicitly classifies these evidence types, evaluates their methodological rigor, and separates their causal conclusions from robust findings in the JSON output.
