Copying text from the Claude Code terminal UI doesn't reach the system clipboard (Windows 10)

Summary

Selecting and copying text (cut & paste) from the Claude Code terminal/shell UI does not place the text on the Windows system clipboard. Pasting afterward yields nothing / stale content, so command snippets shown in Claude Code can't be copied out the normal way.

Environment

• OS: Windows 10 Pro (10.0.19045)
• Claude Code (CLI), recent build
• Tried from the standard Windows terminal

Steps to reproduce

1. In a Claude Code session on Windows, have Claude output a command (e.g. a long ssh -i "<path>" user@host line).
2. Select that text in the Claude Code shell and copy it (mouse select / Ctrl+C).
3. Paste into another terminal or editor.

Expected

The selected text is on the system clipboard and pastes correctly.

Actual

Nothing usable is copied — the paste does not contain the selected command. The only reliable workaround was to have the assistant write the text to the Windows clipboard out-of-band (Git Bash > /dev/clipboard), then paste.

Impact

Blocks the common workflow of copying a generated command out of Claude Code to run elsewhere. Especially painful under time pressure.

Workaround

Write the string to the clipboard via Git Bash (printf '%s' '<text>' > /dev/clipboard) instead of selecting in the UI.
