How do I install the X Cpu skill?

Run npx skillmds@latest add x-cmd/x-cpu in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is X Cpu safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with X Cpu?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is X Cpu free to use?

Yes. Installing skills from SkillMD is free. This skill is licensed under Apache-2.

x cpu - CPU Information

Display CPU information and detect system endianness.

Quick Start

# Display CPU information (default)
x cpu

# Detect system endianness
x cpu endianness

Features

CPU Info: Display processor details (model, cores, MHz, vendor, cache)
Endianness Detection: Detect system byte order (little/big endian)
Cross-platform: Linux (via /proc/cpuinfo) and macOS (via sysctl)

Commands

Command	Description
`x cpu`	Display CPU information (default)
`x cpu info`	Display CPU information
`x cpu endianness`	Detect system endianness (l/b)

Examples

CPU Information

# Default - show CPU info
x cpu

# Linux output example:
# processor                : 0
# model name               : Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
# cpu cores                : 6
# cpu MHz                  : 2600.000
# vendor_id                : GenuineIntel
# cache size               : 12288 KB

# macOS output example:
# brand_string             : Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz

Endianness Detection

# Detect byte order
x cpu endianness

# Output: l (little-endian) or b (big-endian)

Platform Notes

Linux

Reads from /proc/cpuinfo
Shows: processor, model name, cpu cores, cpu MHz, vendor_id, cache size

macOS

Uses sysctl machdep.cpu
Shows: brand_string, core_count, thread_count, features

About Endianness

Value	Meaning
`l`	Little-endian (x86, x86_64, ARM)
`b`	Big-endian (some MIPS, PowerPC, SPARC)

Most modern systems use little-endian byte order.
