+Tasklets are the building blocks of agents.

+The agent will keep running and take decisions at each step until one of the following conditions is met:
 
 - the task is complete and has been set as such
 - the task is impossible and has been set as such
 - the task times out
 - one of the tools with the `complete_task` flag set to `true` is executed
 
-Several examples of tasklets can be found in the [examples](https://github.com/nerve-ai/nerve/tree/main/examples) directory.
+At each step the agent will receive a conversation history, composed of the initial prompts, the model tool calls and their outputs. The size of this window is determined by the `--window` argument:
+
+- if the window is set to a number `N`, the most recent `N` messages will be shown. **This is the default behaviour with N=15.**
+- if the window is set to `full`, the entire conversation history will be shown to the agent.
+- if the window is set to `summary`, the most recent messages will be shown, while the previous ones will be stripped down.
