Tools of PT Chart
	Description		Read-only	Idempotent	Open world
`convert_units`Convert between pressure units (psig, psia, kpa, bar) and temperature units (F, C). A bare 'psi' is treated as psig. For certified HVAC technicians (EPA 608; A2L certification where required).	Convert between pressure units (psig, psia, kpa, bar) and temperature units (F, C). A bare 'psi' is treated as psig.

`diagnose`Conversational diagnostic copilot: give it field readings and get back computed superheat/subcooling plus a ranked 'check this first' list. For certified HVAC technicians (EPA 608; A2L certification where required). Informational only -- it suggests what to CHECK, never how to defeat a safety device, vent refrigerant, or work uncertified. metering: 'txv' (default) or 'fixed' for fixed-orifice/piston systems.

`pt_lookup`Saturation pressure (bubble and dew, in psig) for a refrigerant at a temperature in Fahrenheit. For certified HVAC technicians (EPA 608; A2L certification where required). Example: pt_lookup("R-454B", 45). Bubble point: use for subcooling calculations. Dew point: use for superheat calculations. Pure fluids (R-32, R-410A, R-22, R-134a) have no glide, so both values match.	Saturation pressure (bubble and dew, in psig) for a refrigerant at a temperature in Fahrenheit.
