What's Wrong?

Custom statusline commands that output OSC 8 hyperlinks no longer render as clickable/underlined text. The escape sequences appear to be filtered or not passed through to the terminal.

What Should Happen?

The statusline text containing OSC 8 hyperlink sequences should render as:

• Underlined (visual indicator of hyperlink)
• Clickable (Ctrl+click or Cmd+click triggers the URL)

Error Messages/Logs

No error messages. The text simply renders as plain text instead of a hyperlink.

Steps to Reproduce

1. Create a minimal statusline script (statusline-minimal.sh):

#!/bin/bash
# OSC 8 format: \e]8;;URL\e\\TEXT\e]8;;\e\\
UUID="test-uuid-1234-5678-abcd"
URL="toclipboard://${UUID}"
printf '\e]8;;%s\e\\%s\e]8;;\e\\' "$URL" "$UUID"

1. Create settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "/path/to/statusline-minimal.sh",
    "padding": 0
  }
}

1. Make the script executable and run Claude:

chmod +x statusline-minimal.sh
claude --settings settings.json

1. Observe the statusline - the UUID appears as plain text, not as a clickable hyperlink.

Additional Information

Suspected Cause

Changelog for 2.1.3:

"Improved terminal rendering stability by preventing uncontrolled writes from corrupting cursor state"

This change likely filters or escapes OSC 8 sequences from custom statusline command output.

Use Case

I use a custom statusline that includes a clickable session UUID. I want to be able to Ctrl+click to copy the session UUID to my clipboard, or trigger any other custom URI scheme handler for that matter. The toclipboard:// scheme is just one example - OSC 8 hyperlinks enable integration with any system-registered URI handler.

Technical Context

The OSC 8 hyperlink format is a standard terminal escape sequence:

\e]8;;URL\e\\VISIBLE_TEXT\e]8;;\e\\

This is the same format Claude Code itself uses for file path links, so terminal support is already assumed for the target environments.

Recommended Terminal for Testing

For reliable OSC 8 hyperlink support, use VS Code integrated terminal or any fork thereof (Cursor, Windsurf, etc.). These terminals have robust OSC 8 implementation.
