## In brief

- Agent Skills now belongs to the Linux Foundation rather than a single AI company.
- The article explains where Claude Code, Codex and Gemini CLI each look for skills.
- It provides a complete writing-quality skill that can be added to these agents today.

## Why it matters

Skills become a shared format across major coding agents rather than a vendor-specific feature, so a skill written once can be reused across tools.

## What to do

- Install the writing-quality skill from the article into Claude Code, Codex or Gemini CLI
