    cannot_create_events!

    description <<-MD
      This agent is triggered by schedule or an incoming event and commands other agents ("targets") to run, disable or enable themselves.

      # Action types

      Set `action` to one of the action types below:

      * `run`: Target Agents are run when this agent is triggered.

      * `disable`: Target Agents are disabled (if not) when this agent is triggered.

      * `enable`: Target Agents are enabled (if not) when this agent is triggered.

      Here's a tip: you can use Liquid templating to dynamically determine the action type.  For example:

      - To create a CommanderAgent that receives an event from WeatherAgent every morning to kick an agent flow that is only useful in a nice weather, try this: `{% if conditions contains 'Sunny' or conditions contains 'Cloudy' %}run{% endif %}`

      - Likewise, if you have a scheduled agent flow specially crafted for rainy days, try this: `{% if conditions contains 'Rain' %}enable{% else %}disabled{% endif %}`

      # Targets

      Select Agents that you want to control from this CommanderAgent.
