What's Wrong?

Description:

When I type a message containing the word "workflow," Claude Code shows a banner along the lines of "Using dynamic workflow — press cmd-w to stop"
(cycling in rainbow colors). The problem is that cmd-w is the universal close-window shortcut in macOS terminal emulators (Terminal.app, iTerm2,
Ghostty, etc.), so pressing it doesn't cancel the workflow — it closes the terminal window and kills the entire Claude Code session, losing the
in-progress conversation.

Steps to reproduce:

1. On macOS, open Claude Code in Terminal.app or iTerm2.
2. Send a message that mentions the word "workflow" in casual conversation (not actually requesting one).
3. Observe the "press cmd-w to stop" banner.
4. Press cmd-w expecting to dismiss the banner.
5. The terminal window closes and the session is lost.

Expected: A cancel shortcut that doesn't shadow a standard terminal keybinding — e.g. esc, ctrl-c, or cmd-shift-w.

Actual: cmd-w closes the terminal window, ending the session and losing conversation context.

Environment:

• macOS (Darwin 24.6.0)
• zsh
• Terminal emulator: iTerm2
• Claude Code version: 2.1.153 (Claude Code)

Additional notes:

• The trigger appears to be the literal word "workflow" appearing in the prompt, even when the user isn't asking for multi-agent orchestration. A

less aggressive trigger (or one that requires an explicit /workflow invocation) would also reduce accidental activations.

• Suggested alternatives for the cancel chord: esc (matches how most other Claude Code prompts cancel), or ctrl-c (standard terminal interrupt).

What Should Happen?

Don't trigger on just typing the word, and don't suggest Cmd-W as a keyboard shortcut.
