Claude

Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):

git clone --depth 1 https://github.com/huytieu/COG-second-brain.git
cp -r COG-second-brain/skills/update-cog ~/.claude/skills/update-cog   # personal, or .claude/skills in a project

In the Claude apps, zip the update-cog folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

ChatGPT / Codex

Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:

git clone --depth 1 https://github.com/huytieu/COG-second-brain.git
cp -r COG-second-brain/skills/update-cog .agents/skills/update-cog   # repo; ~/.agents/skills for all projects
