Clean Up Messy Claude Code Terminal Pastes in One Click

The Problem: Messy Terminal Copies

When you copy a multi-line command or prompt from the Claude Code terminal, you often get extra baggage: the leading ❯ prompt character and broken whitespace from line wrapping. This forces you to manually clean the text before you can paste it into a document, another chat, or use it as a new prompt. It's a small but frequent friction point in an otherwise smooth workflow.

The Solution: A Single-Purpose Web Tool

Simon Willison's new Cleanup Claude Code Paste tool solves this. It's a minimalist web page with one job:

1. Remove the prompt character: Strips the leading ❯ from pasted text.
2. Fix wrapped-line whitespace: Intelligently joins lines that were broken by the terminal's width.
3. Output clean text: Provides a clean, copyable block of text.

How to use it:

1. Copy any multi-line output from your Claude Code terminal session.
2. Navigate to the tool's webpage.
3. Paste (Cmd+V or Ctrl+V) directly into the page. The cleaning happens automatically.
4. Click the "Copy to clipboard" button to grab the cleaned version.

No installation, no configuration. It works entirely in your browser.

Why This Matters for Your Workflow

This tool addresses a specific pain point in the Claude Code agentic workflow. When Claude generates a complex shell command or a detailed prompt for a follow-up task, you might want to save it. A clean copy is essential for:

• Documentation: Adding commands to your project's CLAUDE.md or README.
• Iteration: Using a cleaned prompt as a starting point for a more refined request.
• Sharing: Sending a precise instruction to a colleague without terminal artifacts.

While niche, it eliminates a manual step that interrupts your flow. This follows a trend of developers creating hyper-focused tools to smooth out edges in the AI-assisted development experience, a space where Claude Code has seen significant activity, appearing in 60 articles just this week.

A Native Workaround

For a keyboard-driven solution, you can often achieve a similar result by using your terminal's built-in copy functions. In many terminal emulators, you can:

1. Select the text you want (excluding the ❯).
2. Use a "Copy Selection" shortcut (often Cmd+Shift+C on macOS, Ctrl+Shift+C on Linux/Windows).
   This method bypasses the line-wrapping issue if your selection is precise, but the web tool is more forgiving and handles bulk pastes effortlessly.
