CLI Tools Skill

Manage CLI tool installation, environment auditing, and updates.

Capabilities

Reactive: Auto-install missing tools on "command not found"
Proactive: Audit project dependencies and tool versions
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:

Binary	Package (Homebrew)	Package (apt)
`rg`	`ripgrep`	`ripgrep`
`fd`	`fd`	`fd-find`
`bat`	`bat`	`bat`
`delta`	`git-delta`	N/A
`exa` / `eza`	`eza`	`eza`
`fzf`	`fzf`	`fzf`
`ag`	`the_silver_searcher`	`silversearcher-ag`
`http`	`httpie`	`httpie`
`jq`	`jq`	`jq`
`yq`	`yq`	N/A
`gh`	`gh`	`gh`
`glab`	`glab`	N/A

Installation Commands

macOS (Homebrew)

bash

# 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)

bash

# 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)

bash

# Global PHP tools
composer global require phpstan/phpstan

# 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"

Auto-Install Workflow

When a command fails with "command not found":

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

Example:

bash

# 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:

bash

# macOS
brew update && brew upgrade

# Linux
sudo apt update && sudo apt upgrade

# PHP global tools
composer global update

# Node global tools
npm update -g
