Summary

This skill provides expert guidance for developing React applications, including app-v2 architecture, standalone tools, Vercel deployment, and PolicyEngine-specific UI patterns.

  • It helps developers build, deploy, and maintain frontend components and interactive tools efficiently.

Overview

Generated Claude Code wrapper for PolicyEngine.

Results are estimates. PolicyEngine simulates a large, evolving body of tax-benefit law (the US model alone encodes more than 95,000 parameters across 5,500+ variables) over calibrated survey microdata. Treat microsimulation outputs as estimates, and validate them against the policies relevant to your analysis, the scope of the rules engine, and external or back-of-the-envelope calculations. Inspect the US dataset's calibration at https://calibration-diagnostics.vercel.app/populace.

This repository is built from PolicyEngine/policyengine-skills. Do not edit it directly unless you are fixing a sync emergency.
