What's Wrong?

Description:
When typing a slash command that exactly matches an option in the completion list, the selection defaults to the second item instead of the first (exact match).

Steps to Reproduce:

1. Start typing /clear in the CLI
2. Immediately / command choices appear, intially they all look to be custom slash commands. The first on the list is highlighted, in this case “/session-end”
3. As I type / -> c the custom commands matching that patter appear at the top of the list and “/session-end” moved down the list, but still highlighted blue and so selected.
4. By the time I get to /–> c –> l – > e –> a –> r in the typing /clear is at the top and /session-end is in the second spot, but still blue and selected
5. So even though my deisred command has been typed in full the second on the list remains selected, and whe I Press Enter to confirm the /session-end command is entered.

Actual Behavior:
The second item in the completion list is selected/executed instead of the exact match.

Workaround:
Adding a space after the command (e.g., /clear ) executes correctly.

Environment:

• OS: macOS (Darwin 25.2.0)
• Claude Code version: 2.1.12

What Should Happen?

Expected Behavior:
The exact match (/clear) should be selected and executed.
