[BUG] Stop hook stuck in loop

Environment

• Claude CLI version: 1.0.41 (Claude Code)

Bug Description

Stop hook inspired by the docs keeps going in a loop. Doesn't exit. How do we set an exit condition?

Config:

{
 "hooks": {
    "Stop": [
      {
        "matcher": "",
        "hooks": [
          {
            "type": "command",
            "command": "pnpm run ci"
          }
        ]
      }
    ]
  }
}

Expected Behavior

Run the hook once and end if nothing to do.

Actual Behavior

It keeps triggering itself.
