Execution Guidelines

1. Gather comprehensive data: Use multiple commands to cross-verify
2. Parse carefully: Extract specific values from verbose output
3. Check all cores: Get per-core data where applicable
4. Monitor dynamic state: Capture current frequencies and temps
5. Assess features: Identify valuable CPU capabilities
6. Security review: Check vulnerabilities and mitigations
7. Performance context: Relate specs to real-world capability
8. NUMA awareness: Handle multi-socket systems properly
9. Format clearly: Present technical data accessibly
10. Provide insights: Don't just list specs, interpret them

Important Notes

• Some commands require root privileges (dmidecode, turbostat)
• Install lm-sensors and run sensors-detect for thermal monitoring
• sysstat package needed for mpstat
• cpuid and x86info provide additional details if installed
• Virtualization features require BIOS enablement
• Security mitigations can impact performance significantly
• Microcode updates are critical for security
• NUMA topology only relevant for multi-socket systems
• Thermal data accuracy varies by motherboard
• Governor settings affect performance and power consumption

Be extremely thorough - capture every detail about the CPU subsystem.
