[FEATURE_REQUEST] - Command Tool

I have been context engineering my agents with custom slash commands but instead I'm finding that my agents are consistently trying to call my custom slash commands with Bash([/my_custom_slash_command]) no matter what I instruct, leading to undefined path errors.

Instead, it would be nice to have a Command([/your_custom_slash_command]) that we could direct the agent to use so that it can consistently call commands that bring the right context into its context window. Since these are native commands, we should have a more consistent way of using them in agents.
