Catastrophe Model Validation Assistant
Validate catastrophe models with automated testing and compliance checks
What You Can Do
This skill automates the validation of catastrophe risk models by testing parameter assumptions, verifying output accuracy, and documenting compliance with industry standards. You provide your model specifications, historical data, and outputs—Claude generates comprehensive validation reports, identifies assumption inconsistencies, and flags compliance gaps. It streamlines the governance process and reduces manual review time.
Features
Automatically test model parameters (hazard curves, vulnerability functions, financial terms) against industry benchmarks and your specifications
Compare modeled loss predictions against actual historical claims to identify systematic biases or outliers
Systematically verify all model assumptions (peril correlations, coverage limits, deductibles) and document their justification
Cross-reference model against regulatory requirements (Solvency II, insurance accounting standards, internal governance)
Guide you through stress-testing critical assumptions and document how changes in key parameters affect results
Produce professional validation reports with executive summary, findings, remediation actions, and sign-off templates
Create standardized templates for model assumptions, methodology, and validation procedures to support audits
Example Output
Validation Report: Hurricane Model Q3 2026
