Installation
npx skills— The package manager for the open Agent Skills ecosystem. One command to install skills into any AI coding agent.
Install Skills
# Browse all 20 available skills
npx skills add sanjay3290/ai-skills --list
# Install a single skill (auto-detects your agent)
npx skills add sanjay3290/ai-skills --skill postgres
# Install multiple skills at once
npx skills add sanjay3290/ai-skills --skill postgres --skill mysql --skill mssql
# Install all skills
npx skills add sanjay3290/ai-skills --all
Target Specific Agents
Use -a to install into a specific agent's skills directory:
# Install for Claude Code
npx skills add sanjay3290/ai-skills --skill postgres -a claude-code
# Install for multiple agents at once
npx skills add sanjay3290/ai-skills --skill postgres -a claude-code -a gemini-cli -a cursor
# Install all skills into all supported agents
npx skills add sanjay3290/ai-skills --all -a '*'
Global vs Project Install
By default, skills install to the current project directory. Use -g for global (user-level) installation:
# Global install — available in all projects
npx skills add sanjay3290/ai-skills --skill imagen -g
# Project install (default) — scoped to current repo
npx skills add sanjay3290/ai-skills --skill imagen
Supported Agents
The skills CLI supports 40+ agents. Here are the most common:
