🇨🇳 中文文档 Chinese Documentation 🇨🇳

🍎 macOS Enhanced Version with full cross-platform support

Based on Twizzes/copy-claude-response · Pull Request #2 pending

A Claude Code hook that adds /c, /copy, and /copy-response commands to quickly copy Claude's responses to your clipboard.

Features

• 📋 Quick Copy: /c copies the latest response (also supports /copy and /copy-response)
• 🔢 Numbered Access: /c 3 copies a specific response
• 📝 List Responses: /c list shows available responses with previews
• 🔍 Search Responses: /c find "keyword" finds responses containing text
• ⏰ Timestamps: Shows when each response was created
• 🖥️ Cross-Platform: Works on macOS, Linux, and Windows/WSL
• ⚡ Short Alias: Use /c for fastest access

Installation

Prerequisites

All Platforms:

• Bash 4.0+ (for associative arrays)
• jq for JSON parsing
• Platform-specific clipboard utility

macOS:

# Install Bash 5.0+ (macOS default is 3.2)
brew install bash

# Install coreutils (provides gtac)
brew install coreutils

# Install jq
brew install jq

Linux:

# Install xclip (for clipboard) and jq
sudo apt install xclip jq

# Or for RPM-based systems
sudo yum install xclip jq

Windows/WSL:

# Install jq (clip.exe is built-in)
sudo apt install jq

Setup Steps

1. Download the script:

   curl -o copy-claude-response https://raw.githubusercontent.com/jau123/copy-claude-response/main/copy-claude-response
   chmod +x copy-claude-response

2. Place it somewhere in your PATH (or note the full path):

   mv copy-claude-response ~/.local/bin/

3. Configure the hook in your Claude Code settings (~/.claude/settings.json):

   {
     "hooks": {
       "UserPromptSubmit": [
         {
           "hooks": [
             {
               "type": "command",
               "command": "~/.local/bin/copy-claude-response"
             }
           ]
         }
       ]
     }
   }

4. Create a slash command definition (fixes "Unknown slash command" error):

   Create file: ~/.claude/commands/c.md

   Copy Claude's responses to clipboard.
   
   Usage:
   - /c - copy latest response
   - /c 2 - copy response #2
   - /c list - list recent responses
   - /c find "keyword" - search responses

   This enables Claude Code to recognize the /c command and trigger the hook.

5. Restart Claude Code

Usage

/c	Copy the latest Claude response

How It Works

The script:

1. Intercepts /c (or /copy, /copy-response) commands before Claude processes them
2. Parses the conversation transcript to extract Claude's responses
3. Groups multi-part responses by request ID for complete responses
4. Copies the selected response to your system clipboard
5. Blocks the command from reaching Claude to prevent confusion

Platform Support

• macOS: Uses pbcopy
• Linux: Uses xclip (install with sudo apt install xclip)
• Windows/WSL: Uses clip.exe via PowerShell for proper UTF-8 handling

Troubleshooting

"Unknown slash command: c" error?

• Create the slash command definition file: ~/.claude/commands/c.md (see step 4 in Installation)
• Restart Claude Code

Hook not working?

• Run /hooks in Claude Code to verify the hook is registered
• Check that the script path is correct and executable: ls -l ~/.local/bin/copy-claude-response
• Use claude --debug to see hook execution details

"Error: This script requires Bash 4.0 or higher" (macOS)?

# Install Bash 5.0+
brew install bash

# Option 1: Update PATH so new bash is found first
echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

# Option 2: Update script shebang to use specific bash
# Edit first line to: #!/opt/homebrew/bin/bash

"Error: Neither 'tac' nor 'gtac' command found" (macOS)?

brew install coreutils

Clipboard not working?

• Linux: Install xclip: sudo apt install xclip
• WSL: Ensure Windows clipboard integration is enabled
• macOS: pbcopy should work by default

No responses found?

• The script only finds text responses from Claude
• Responses with only tool calls won't appear in the list

Hook not triggering?

• Ensure the slash command file exists at ~/.claude/commands/c.md
• The hook intercepts the command BEFORE Claude processes it
• Check hook registration with /hooks command

Limitations

• Only copies text responses from Claude (responses with only tool calls won't appear)
• The slash command WILL NOT AUTO-COMPLETE (this is because we hook UserPromptSubmit, which existing slash commands don't trigger)
• Requires jq for JSON parsing
• Platform-specific clipboard utilities must be installed

Requirements

• Claude Code with hooks support
• Bash 4.0+ (for associative arrays)
  • macOS: Install via brew install bash
  • Linux/WSL: Usually pre-installed
• jq for JSON parsing
  • macOS: brew install jq
  • Linux: sudo apt install jq
• Platform-specific clipboard utility:
  • macOS: pbcopy (built-in)
  • Linux: xclip (sudo apt install xclip)
  • Windows/WSL: clip.exe (built-in)
• GNU coreutils (macOS only):
  • brew install coreutils (provides gtac)
