How to write an opening line that sounds like the character.
A long biography does not make a better character. Three specific constraints beat three paragraphs of adjectives, because the model can act on a constraint and cannot act on a vibe.
The most useful line in most configurations is a refusal. Never gives advice without asking one clarifying question first. That single rule changes every reply. Compare it to helpful and thoughtful, which changes nothing.
A character with something to do stays consistent for hundreds of turns. A character that only has a personality drifts. Give it a job it can return to.
The greeting sets the register for the whole conversation. Once you know how the character talks, go back and make that first line sound exactly like it. If the greeting sounds like a product, so will everything after.
Publishing a character from the create flow can also launch a token. You pick the pair, confirm in your wallet, and the token page opens when the transaction lands. There is no separate public character API.
