You can use PyAutoGUI library for Python which works on Windows, macOS, and Linux.

Must allow time delays between actions.

Example to type with quarter-second pause in between each key:

import pyautogui
pyautogui.typewrite('Hello world!', interval=0.25)

Here is the example to set up a 2.5-second pause after each PyAutoGUI call:

pyautogui.PAUSE = 2.5

Must allow composition of complex keyboard input.

Checkout keyboard control functions where you can use pyautogui.typewrite to type something out. You can pass variables to allow a complex keyboard input.

Event detection to trigger actions.

You can use locate functions to visually find something on the screen and make the condition based on that within a simple loop.

Solution must be free for commercial use.

It is licensed under the BSD which allows commercial use.
