 - `{{command[1]}}`: The first argument of the command (the command itself has index of 0)
 - `{{command[2:5]}}`: The second to fifth arguments. If any of the side is not specified, them it defaults to the start (if it is left) or the end (if it is right).
 
+The suggestion can have additional conditions to check. To specify the conditions, add a `#[...]` at the first line (just like derive macros in Rust). Available conditions:
+
+- `executable`: Check if the argument can be found by `which`
+- `cmd_contains`: Check if the last user input contains the argument
+- `err_contains`: Check if the error of the command contains the argument
