unitility

Use this skill whenever you need to verify, validate, or cross-check thermodynamic property calculations for water/steam, ice Ih, humid air against IAPWS reference standards. Triggers include: implementing a new IAPWS equation (IF97, R10-06, R14-08), verifying computed properties against reference values, generating test data points, checking sublimation/melting curves, or comparing Java implementation results with Python iapws library. Also trigger when the user mentions iapws, Wagner et al., IAPWS releases (R7-97, R10-06, R14-08), or asks to verify thermodynamic calculations.

Use this skill whenever working with the UNITILITY Java library (com.synerset:unitility-core) for type-safe physical quantities in Java 21+. Triggers include: creating quantities (Temperature, Pressure, Distance, Mass, Velocity, Flow, Humidity, etc.), unit conversions between SI and Imperial units, arithmetic on physical quantities, comparing or sorting quantities, engineering-format output, or integrating Unitility with Spring Boot / Quarkus. Also trigger when the user mentions PhysicalQuantity, unit-safe calculations in Java, HVAC/thermodynamic calculations with units, or any quantity class name.
