Installation

Marketplace (Recommended)

Add the Netresearch marketplace once, then browse and install skills:

# Claude Code
/plugin marketplace add netresearch/claude-code-marketplace

npx (skills.sh)

Install with any Agent Skills-compatible agent:

npx skills add https://github.com/netresearch/cli-tools-skill --skill cli-tools

Download Release

Download the latest release and extract to your agent's skills directory.

Git Clone

git clone https://github.com/netresearch/cli-tools-skill.git

Composer (PHP Projects)

composer require netresearch/cli-tools-skill

Requires netresearch/composer-agent-skill-plugin.

npm (Node Projects)

npm install --save-dev \
  @netresearch/agent-skill-coordinator \
  github:netresearch/cli-tools-skill

Requires @netresearch/agent-skill-coordinator, which discovers the skill in node_modules and registers it in AGENTS.md via a postinstall hook. For pnpm, also allowlist the coordinator's postinstall:

{
  "pnpm": {
    "onlyBuiltDependencies": ["@netresearch/agent-skill-coordinator"]
  }
}

Triggers

The skill activates automatically on:

Error Patterns

bash: <tool>: command not found
zsh: command not found: <tool>
'<tool>' is not recognized as an internal or external command

User Requests

• "check environment", "audit tools"
• "what's missing", "what's outdated"
• "install development tools"
• "update all tools"

Installation Methods

The skill selects the optimal installation method based on catalog priority:

1. GitHub Release Binary - Direct download (fastest, no deps)
2. Cargo - Rust tools via cargo install
3. UV/Pip - Python tools
4. NPM - Node tools
5. Apt/Brew - System packages (fallback)

Priority: user-level (~/.local/bin, ~/.cargo/bin) over system-level.
