What's Wrong?

I have this in ~/.claude/settings.json

  "hooks": {
    "Stop": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "\"/Users/adam/.claude/hooks/claude4ever.py\" \"$CLAUDE_PROJECT_DIR\""
          }
        ]
      }
    ],
    "SessionEnd": [
      {
        "hooks": [
          {
            "type": "command",
            "command": "\"/Users/adam/.claude/hooks/claude4ever.py\" \"$CLAUDE_PROJECT_DIR\""
          }
        ]
      }
    ]
  },

This worked perfectly until a few days ago. Now it just doesn't do anything .

You can replace "/Users/adam/.claude/hooks/claude4ever.py" by "say" on macOS. Same thing.

What Should Happen?

Hooks should work, as they did a few days ago
