Cross-Platform Installation

Most tools auto-discover skills in

.agent/skills/

# Universal installation (works with most tools)
git clone https://github.com/user/skills .agent/skills

Platform-Specific Notes

Claude Code

Auto-discovers from
```
.claude/skills/
```
and
```
~/.claude/skills/
```
Supports
```
/init
```
command for context bootstrapping

Codex (OpenAI)

Supports multiple scopes: REPO, USER, ADMIN, SYSTEM
Built-in
```
$skill-creator
```
and
```
$skill-installer
```
Restart required after installing new skills

GitHub Copilot

Skills in
```
.github/skills/
```
directory
Uses
```
SKILL.md

Copilot auto-activates based on description match

Gemini CLI

Use
```
@
```
symbol to attach skill files to prompts
Place skills in
```
.gemini/skills/
```
or
```
.agent/skills/
```

Conversion Tips

Same SKILL.md format works across platforms
Change only the installation path for different platforms
Test on each target platform before distribution
Document platform-specific requirements in skill README
