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:

Agent	-a Flag	Project Directory	Global Directory
Claude Code	claude-code	.claude/skills/	~/.claude/skills/
Gemini CLI	gemini-cli	.gemini/skills/	~/.gemini/skills/
Cursor	cursor	.cursor/skills/	~/.cursor/skills/

Manual Installation (Alternative)

Clone entire repository

git clone https://github.com/sanjay3290/ai-skills.git ~/.claude/skills/ai-skills

Copy individual skills

cp -r skills/postgres ~/.claude/skills/

Symlink for development

ln -s /path/to/ai-skills/skills/postgres ~/.claude/skills/postgres

Replace ~/.claude/skills/ with the appropriate directory for your agent (see table above).

Skill Setup

Each skill may require additional configuration:

Postgres / MySQL / MSSQL

Create connections.json in the skill directory with your database credentials. See postgres/README.md, mysql/README.md, or mssql/README.md.

# Install drivers for whichever databases you use
pip install psycopg2-binary     # PostgreSQL
pip install mysql-connector-python  # MySQL
pip install pymssql              # MSSQL

Imagen & Deep Research

export GEMINI_API_KEY=your-api-key

Get a free key at Google AI Studio.

Note: Deep Research tasks take 2-10 minutes and cost $2-5 per query.

Outline

export OUTLINE_API_URL=https://your-wiki.example.com/api  # Optional

Get your API key from your Outline wiki settings.

Jules

# Install CLI (one-time)
npm install -g @google/jules

# Authenticate (opens browser)
jules login

Connect your GitHub repos at jules.google.com. Jules works asynchronously - create a task, it runs in the background, then pull results when complete.

Manus

export MANUS_API_KEY=your-api-key

Get your API key from manus.im settings. Manus excels at deep research, market analysis, product comparisons, and generating comprehensive reports with visualizations.

ElevenLabs

pip install -r skills/elevenlabs/requirements.txt  # Only needed for PDF/DOCX

Google Workspace Skills

Each Google Workspace skill requires the keyring library and first-time authentication:

# Install dependency (one-time)
pip install keyring

# Authenticate for the skill you need (opens browser)
python ~/.claude/skills/ai-skills/skills/google-chat/scripts/auth.py login
python ~/.claude/skills/ai-skills/skills/google-docs/scripts/auth.py login
python ~/.claude/skills/ai-skills/skills/google-sheets/scripts/auth.py login
python ~/.claude/skills/ai-skills/skills/google-slides/scripts/auth.py login
