Verify the package exists: Use brew search <name> to confirm availability
Determine the correct type:
- tap "repository" - Third-party repositories
- brew "package" - Command-line tools and libraries
- cask "package" - GUI applications
- mas "App Name", id: 123456 - Mac App Store apps
- vscode "extension-id" - VS Code extensions
Add to Brewfile:
- Place in the appropriate section
- Maintain alphabetical order within each section
- Add explanatory comment if needed (e.g., # Database for development)
Confirm the addition: Tell the user what was added and where

2. Removing Packages

When removing packages:

Locate the package in the Brewfile
Confirm with the user before removing
Remove the line and any package-specific comments
Clean up any extra blank lines

3. Updating and Organizing

When organizing the Brewfile:

Group by type: Keep taps, brews, casks, mas, and vscode sections together
Alphabetical order: Sort entries within each section
Preserve comments: Keep section headers and explanatory notes
Consistent formatting: No extra blank lines between same-type entries

4. Information and Search

When asked about packages:

List installed: Show what's in the Brewfile
Search packages: Use brew search <term> to find packages
Package info: Use brew info <package> for details
Explain differences: Clarify formula vs. cask when relevant

Brewfile Structure

# Taps - Third-party repositories
tap "homebrew/cask-fonts"
tap "oven-sh/bun"

# Brews - Command-line tools
brew "git"
brew "node"
brew "ripgrep"

# Casks - GUI Applications
cask "visual-studio-code"
cask "warp"

# Mac App Store Apps
mas "Xcode", id: 497799835

# VS Code Extensions
vscode "dbaeumer.vscode-eslint"

Best Practices

Verify before adding: Always check the package exists with brew search
Use proper quotes: Double quotes for all package names
British English: Use British spelling in all comments (e.g., "optimise" not "optimize")
Be specific: If multiple packages match, ask the user which one they want
Preserve structure: Maintain the existing organisation and comments
Test knowledge: Read the current Brewfile first to understand what's installed

Example Workflow

User: "Add ripgrep"

Steps:

Run brew search ripgrep to verify
Identify it's a formula (brew)
Add brew "ripgrep" in alphabetical order in the brew section
Confirm: "Added brew 'ripgrep' to Brewfile"

User: "Install Visual Studio Code"

Steps:

Search: brew search visual-studio-code
Identify it's a cask
Add cask "visual-studio-code" in the cask section
Confirm addition

Important Notes

Never remove packages without confirmation
Always verify packages exist before adding
Maintain alphabetical order within sections
Ask for clarification when package names are ambiguous
Use British English in all communication and comments
