description

Required on every Catalog Entry—Hooks and Presets. It is the summary the /hooks panel shows:

{
  "local": {
    "no-env-access": {
      "description": "Blocks reads and writes to .env files.",
      "event": "tool_call",
      "shell": "false"
    }
  }
}

• Type string · required · every Hook and Preset
• Shown as the identifying summary in /hooks when a reader decides whether to enable or edit the entry.
• Not the Event or the command: event, shell, when, and filter carry behavior, while description only explains it.
