CLI Tools Skill

A Claude Code skill for automatic CLI tool management. Detects missing tools, installs them via optimal package managers, and audits project environments.

Installation

Option 1: Via Netresearch Marketplace (Recommended)

/plugin marketplace add netresearch/claude-code-marketplace

Then browse skills with /plugin.

Option 2: Download Release

Download the latest release and extract to ~/.claude/skills/cli-tools/

Option 3: Manual Installation

# Copy to your skills directory
cp -r cli-tools ~/.claude/skills/

Manual Usage

# Install a specific tool
./scripts/install_tool.sh ripgrep install

# Detect project type
./scripts/detect_project_type.sh json .

# Audit environment
./scripts/check_environment.sh audit .

# Update all tools
./scripts/auto_update.sh update

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• "what's missing", "what's outdated"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.
