agentskills-cli

Universal Agent Skills installer — one command to install skills across Claude Code, Codex, Trae, Cursor, Gemini CLI, and 20+ AI coding tools.

npm install -g @jahonn/agentskills-cli

Problem

You write an Agent Skill. You want it in Claude Code, Codex, Cursor, and Trae. That's 4 manual copies to 4 different directories. If you update the skill, copy again.

One skill, many tools. One command.

# Before
cp my-skill ~/.claude/skills/
cp my-skill ~/.codex/skills/
cp my-skill ~/.cursor/rules/
cp my-skill ~/.trae/skills/

# After
agentskills install ./my-skill -t all
