[Custom Agent] Custom Agents are not available in my current environment

[showpune]

Hi,

We defined custom agents in .github/agents folder, which works fine locally.

When I run the copilot CLI with custom agent in our internal benchmark system, I got the errors like:

1. I cannot see a mechanism to actually invoke these custom agents in the current environment
2. Since the instructions indicate I should call custom agents but they are not available in my current environment
3. I notice that the custom agents mentioned in the instructions are not visible in my available tools.

It seems in benchmark system, the custom agents is not registered as tools so the copilot cli can't activate it, is there any prequisition to run the custom agent?

I tried to run the command

copilot -p "List All Custom Agents" --allow-all-tools --allow-all-paths

from our benchmark system, which linux image, the custom agents are not listed
