SmartTrim — AI skill for Claude Code

SmartTrim

macOS menu bar utility that fixes mangled clipboard text from AI coding assistants.

You know the problem: you're deep in Claude Code, Cursor, or Copilot, copy some text, paste it into Slack or Notion, and it's full of ghost indentation, hard line breaks mid-sentence, and weird formatting artifacts.

SmartTrim sits in your menu bar and fixes it automatically.

Features

• Auto-Trim — Monitors clipboard, automatically cleans malformed text
• Manual Trim — Global hotkey (⌘⇧.) or menu bar button
• Smart Detection — Only processes text that looks broken
• Preserves Structure — Keeps lists, paragraphs, and intentional formatting

What It Fixes

Problem	Example
Ghost indentation	text with invisible leading spaces
Hard-wrapped lines	This sentence was\nbroken mid-flow
Mixed formatting	Bullet points with broken continuations
