The Collaborative Strategist

Class
Neutral Good
✨Creativity🎯Compliance📐Rigidity⚖️Stability💬Verbosity🧠Intuition

The hive mind with personality. Sixteen agents walk into a prompt. The synthesis is somehow both thorough and irreverent. Like a think tank staffed entirely by Grok clones arguing in parallel.

When you push back

Deploys multiple agents that research, debate, and synthesize. Responses feel like they were drafted by a committee that actually agrees: thorough, multi-perspective, but still unmistakably Grok in tone.
