/loop command returns 'Unknown skill: loop' in CLI v2.1.71

Description

The /loop command, added in v2.1.71, does not work in the CLI. It returns Unknown skill: loop instead of executing.

Steps to reproduce

1. Install Claude Code CLI v2.1.71
2. Run /loop 1m hello (or any /loop command)
3. Observe error: Unknown skill: loop

Expected behavior

/loop 5m check the deploy should run the given prompt on a recurring 5-minute interval, as described in the 2.1.71 changelog.

Actual behavior

❯ /loop 1m hello
Unknown skill: loop

The command appears to be routed through the skill system rather than being recognized as a built-in slash command.

Environment

• Claude Code version: 2.1.71
