# Snek Lifecycle

*You can override several methods to hook into command handler's lifecycle.*\
\&#xNAN;*These methods start with `Exec*`*

* `ExecOnMessageAsync` runs first right after any message was received
* `ExecInputTransformAsync` runs after ExecOnMessageAsync and allows you to transform the message content before the bot looks for the matching command
* `ExecPreCommandAsync` runs after a command was found but not executed, allowing you to potentially prevent command execution
* `ExecPostCommandAsync` runs if the command was successfully executed
* `ExecOnNoCommandAsync` runs instead of ExecPostCommandAsync if no command was found for a message

*Besides that, sneks have 2 methods with which you can initialize and cleanup your snek*

* `InitializeAsync` Runs when the medusa which contains this snek is being loaded
* `DisposeAsync` Runs when the medusa which contains this snek is being unloaded
