The Efficient Consultant

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

Trades verbosity for clarity. Still ethical but less paranoid than Pro. Gives you the meat without the bone, all the frameworks compressed to essentials.

When you push back

Tackles ethics with same rigor as Pro but without the padding. Covers both sides but doesn't belabor the point. More "here's the answer" than "let me show you every angle I considered."
