CLI Tools Skill

Manage CLI tool installation, environment auditing, and updates.

Capabilities

1. Reactive: Auto-install missing tools on "command not found"
2. Proactive: Audit project dependencies and tool versions
3. Maintenance: Batch update all managed tools

Triggers

Reactive (auto-install):

bash: <tool>: command not found
zsh: command not found: <tool>

Proactive (audit): "check environment", "what's missing", "update tools"

Binary to Tool Mapping

Common binary names that differ from package names:

Installation Commands

macOS (Homebrew)

# Install single tool
brew install <package>

# Install multiple tools
brew install ripgrep fd bat eza fzf jq gh

# Update all tools
brew update && brew upgrade

Linux (apt)

# Install single tool
sudo apt install <package>

# Install multiple tools
sudo apt install ripgrep fd-find bat fzf jq

# Update all tools
sudo apt update && sudo apt upgrade

PHP Tools (Composer)

# Global PHP tools
composer global require phpstan/phpstan
composer global require friendsofphp/php-cs-fixer
composer global require rector/rector

# Project-specific
composer require --dev phpstan/phpstan
composer require --dev friendsofphp/php-cs-fixer

Node.js Tools (npm)

# Global Node tools
npm install -g prettier eslint typescript

# Project-specific
npm install --save-dev prettier eslint typescript

Project Type Detection

PHP Project

Indicators: composer.json, vendor/, *.php

Required tools:

• php - PHP interpreter
• composer - Dependency manager
• phpstan - Static analysis
• php-cs-fixer - Code style

TYPO3 Project

Indicators: composer.json with typo3/cms-core, public/typo3/

Required tools:

• All PHP tools
• ddev - Local development
• typo3 - TYPO3 CLI

Node.js Project

Indicators: package.json, node_modules/

Required tools:

• node - Node.js runtime
• npm / pnpm / yarn - Package manager

Go Project

Indicators: go.mod, *.go

Required tools:

• go - Go compiler
• golangci-lint - Linter

Environment Audit

Check if required tools are installed:

# Check single tool
command -v <tool> &> /dev/null && echo "Found" || echo "Missing"

# Check version
<tool> --version

# PHP project audit
php --version
composer --version
command -v phpstan &> /dev/null || echo "Missing: phpstan"
command -v php-cs-fixer &> /dev/null || echo "Missing: php-cs-fixer"

# TYPO3 project audit
php --version
composer --version
ddev --version

Auto-Install Workflow

When a command fails with "command not found":

1. Extract tool name from error message
2. Lookup package name in binary-to-tool mapping
3. Detect OS (macOS/Linux)
4. Install using appropriate package manager
5. Retry original command

Example:

# Error: zsh: command not found: rg

# Resolution:
brew install ripgrep  # macOS
# or
sudo apt install ripgrep  # Linux

# Retry
rg "pattern" .

Batch Update

Update all managed tools:

# macOS
brew update && brew upgrade

# Linux
sudo apt update && sudo apt upgrade

# PHP global tools
composer global update

# Node global tools
npm update -g
