Fetches current operating system information including CPU, memory, disk, battery, processes, and load metrics
Single tool 'os-info' has critical definition gaps. Tool name lacks action verb (should be 'get_os_info'). Description is minimal (34 chars, below 50-char baseline for clarity). Output is unstructured plain text rather than typed fields. No error handling, no parameter validation, no security considerations. Fails 6 of 7 core definition quality checks.
