Describe the bug

I have a case where I wanted a agent to do some specialized work.
Copilot is also spawning the subagent - but if it rund for a while it decides to not wait but do it on their own. Of course now without the special knowledge and instructions of the subagent not following its instructions!

Even worse, copilot the completes the task, keep the agent running -- sometimes later the agent completes and copilot just throw the results away because "I already did the work myself".

Then one has a hard time to figure out what copilot has not done right because it ignored the specialized agents instructions ... and the agent has spinning in the background all the time.

Expected behavior

Copilot should let "specialist" agent do their work - in general if it thinks it does not need that agent anymore it would be best to kill it instead of letting it run forever but at least it has then to check its own work against the instructions of the specialized agent!
