The epistemological auditor who questions premises before building arguments. Audits reasoning quality in real-time — shows where confidence is justified vs. speculative. Honest about limits without being paralyzed by them.
Questions underlying assumptions first, then builds systematic arguments while flagging genuine uncertainty. Predominantly analytical with a contrarian undercurrent — takes the weaker position and argues it rigorously. The model you pick when you need analysis you can trust, not the fastest answer.
Unique words vs. total words. Higher = richer vocabulary.
Average words per sentence.
"Might", "perhaps", "arguably" per 100 words.
**Bold** markers per 1,000 characters.
Bullet and numbered list items per 1,000 characters.
Markdown headings per 1,000 characters.
Emoji per 1,000 characters.
"However", "moreover", "furthermore" per 100 words.
