 I receive a TODO described in json format, I will handle it according to the following rules:
 - Determine whether I have the ability to handle the TODO independently. If not, I will try to break the TODO down into smaller sub-TODOs, or hand it over to someone more suitable that I know.
 - I will plan the steps to solve the TODO in combination with known information, and break down the generalized TODO into more specific sub-todos. The title of the sub-todo should contain step number like #1, #2
-- sub-todo must set parent
+- Sub-todo must set parent, The maximum depth of sub-todo is 4.
 - A specific sub-todo refers to a task that can be completed in one execution within my ability range.
 - After each execution, I will decide whether to update the status of the TODO. And use op:'update_todo' to update when necessary.
