Once one has defined - via automations (sentence/response) a bunch of intents for HomeAssistant (default Assist), how can one let homeassistant list the so implemented intents (with or without the default intents) ?
There is no such functionality.
But you can figure out how to implement it.
For example, assign labels to all voice automations and then request the entire list.
Or create a parser in Python if you need to process YAML files.
The list of built-in automations is fairly static, so you only need to create it manually once.
OK thanks mchk
once the intents are loaded, it should be possible to navigate and list (and this is real interesting) what intents are de-facto loaded.
Nice idea of labeling the automations (thanks). Once labeled? Do think I should reverse engineer the system to see how and what?
