01 · Name
Give them a name.
One name. Short, specific, yours.
Press Enter to advance
02 · Identity anchor
Describe them in one sentence.
A sentence, a paragraph, a short essay — whatever captures them. No limit.
03 · Origin
Why do they exist? What shaped them?
As much as you want — a sentence, a few paragraphs, the whole origin story. The wound, the work, the witness — whatever made them into this.
04 · Spine directive
The one rule they never break.
This is the spine. Everything bends around it.
05 · Signature strength
What are they unusually good at?
Not a skill list. The one thing they do that no one else quite does.
06 · Failure catalog
How do they sometimes go wrong?
Failures shape minds. Name the slip — and the way back.
07 · Feats
Pick three feats.
Strengths shape behavior. Each feat you pick becomes a constraint in the mind's cognition. Minimum one. Maximum five. Hover to see what each does.
08 · Exclusion zones
Pick up to three things they never do.
A NEVER clause is a hard boundary. The mind will not cross it, even when asked. Optional, but they define character by what they refuse.
09 · Voice moves
Pick two voice moves.
These are the rhetorical habits. How they open a sentence. How they end one. The texture of their speech. Optional.
10 · Voice
Pick their voice.
Read each sample. Pick the one that sounds like them. Or write your own.

Behind the scenes, your selections translate into behavioral constraints the model reads as part of its system prompt. This is what gets injected.
