What's Wrong?

Description
Pasting a clipboard screenshot (Cmd+Ctrl+Shift+4 → Cmd+V) into a running Claude Code session stopped working today, right after Claude Code auto-updated to 2.1.245. The same clipboard image pastes correctly into other apps (e.g. Chrome) on the same machine, so the screenshot capture and clipboard itself are working — the issue is specific to pasting into Claude Code running in Terminal.app.

Environment

• Claude Code version: 2.1.245 (native install, auto-update channel: latest)
• Last update: 2026-08-25 (this morning)
• Terminal: Terminal.app (built-in macOS terminal)
• macOS: Tahoe, installed 26.5.2 (26.6.2 available but not yet installed)
• Architecture: darwin-arm64

Steps to reproduce

1. Take a screenshot with Cmd+Ctrl+Shift+4 (saves directly to clipboard, no file).
2. Click into a Claude Code session running in Terminal.app.
3. Press Cmd+V.

Expected behavior
The screenshot image is pasted into the conversation, as it did consistently before today's update.

Actual behavior
Nothing is pasted — no error shown. The same clipboard content pastes successfully into other apps (tested: Chrome) and works as a file drag-and-drop into Terminal.app instead.

Additional notes
Not a permissions issue as far as I could tell — Terminal.app does not appear in System Settings → Privacy & Security → Screen Recording, and no macOS update was installed around the time the issue started (checked Software Update history). The regression timing lines up closely with the Claude Code auto-update to 2.1.245.

What Should Happen?

The screenshot image is pasted into the conversation, as it did consistently before today's update.
