pyre: a macOS system monitor that works around the sudo wall

The full story

pyre is a terminal system monitor for macOS covering CPU, GPU, memory, battery and temperatures, built almost entirely with Claude. The hard part was macOS itself: Apple has no public API for CPU and GPU power draw or detailed thermals on Apple Silicon, the tool with the best numbers, powermetrics, needs root, and ioreg gives only some of the data in a different shape.

The maker pasted raw ioreg and powermetrics output into Claude and asked what each field meant and whether it could be had without sudo. That showed which values overlapped, so pyre has a base tier that needs no permissions and a --detailed flag that asks for sudo explicitly. Claude also suggested caching sensor reads so users aren't asked to re-authenticate every few seconds.
