Guidelines

When the user says "copy this" or "put this in my clipboard", use pbcopy
When the user says "what's in my clipboard?" or "paste", use pbpaste
For transformations, pipe pbpaste through the transform and back to pbcopy
Always confirm what was copied with a brief summary
Never display clipboard contents unless asked — they may contain sensitive data
