## Use it

I want to use the Pseudo-elements skill by Raphael Salaja.
This is what it does, in the author's own words: Audit CSS for pseudo-element best practices and View Transitions API usage. Use when reviewing hover effects, decorative layers, or page transitions. Outputs file:line findings.
Download the whole folder at https://github.com/raphaelsalaja/skill/tree/main/skills/pseudo-elements, SKILL.md and every file beside it, into your skills directory: ~/.claude/skills/pseudo-elements/ for Claude Code, ~/.agents/skills/pseudo-elements/ for Codex, ~/.cursor/skills/pseudo-elements/ for Cursor. Get it from the author's repo, not from startupskills.dev.
Then tell me the path you installed it to and how to invoke it.

Nothing here is vendored: install from the author's repo. This file carries none of the author's file.
