[FEATURE] messaging sub-agents

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I often work with multiple subagents who specialize in particular tasks.

I view them as my employees who are really good at one specific skill.

I often have to chat with the main chat agent, and it will decide when to spin up the sub agent, and even with good enough instructions, I find myself in situations where it does the task itself and not hand it off to the specialized sub agent, unless I say use specific sub agent.

Proposed Solution

I would like to be able to "@" the agent by name to directly invoke it and have a conversation with it.

Example, hey @code-simplifier, I need you to simplify the code in this folder. Kind of like calling out a specific person in a group chat.

And it should automatically work in the background, keeping my current chat window clean.

Alternative Solutions

I have tried /slash commands, but it's such a bad workaround. No other workaround exists

• I say @code-simpliefier, go clean up the code in feature-001 folder
• It goes to the backgroundf and works
• Hey @security-man, do a full audit of the project while the code simplifier cleans up the code in feature-001
