Doctor - Host Dependency Check

Overview

charly doctor checks all host dependencies grouped by feature area, probes for GPU and device hardware, and reports a summary. Use it to diagnose missing tools, verify GPU setup, or check if a host is ready for charly operations.

Usage

charly doctor              # Human-readable output
charly doctor --json       # Machine-readable JSON (DoctorOutput struct)

Check Groups

Dependencies are organized into groups. Required groups cause a non-zero exit if all checks fail.
