what DIY persona prompts is.
The DIY route: write a system prompt that says 'you are X, you believe Y, you write like Z,' or paste a persona card into a custom GPT. Cheap, immediate, and unverifiable — the model performs a sketch of a person from whatever you typed, and nothing distinguishes what they said from what you guessed.
where they differ.
Soulscrape replaces the vibes paragraph with evidence: every behavioral claim in a dossier cites a source and carries a kind — stated belief versus pattern versus speculation. The agent gets an executive model plus an operating manual with revision hooks and a what-not-to-infer section, so it can check its answer against documented positions instead of improvising them.
