What issue are you seeing?

Through this chat '019cdfa0-7d65-7590-90da-7808c4859fe2', we can see that after a while, even if they are automatically closed by the main agent, the multi-agents are no longer available. They will always fail when attempts are made to spawn them in the environment, and I am forced to restart the task from scratch, losing important tokens and context windows that I will need (since I now have to restart the analysis to make them understand what needs to be modified).

Furthermore, I have a maximum of 12 as max_threads in the config.toml file. Initially, I had 10, but I started to notice this “bug” and decided to increase it. As max_depth, I have 2.

I also think that there is no API that the agent can use to view all the multi-agents present.

What steps can reproduce the bug?

What is the expected behavior?

I expect that multi-agents can always be spawned, especially if they are closed.
