A persona in Freelee is four things bundled together:
- A system prompt — the instruction that defines behaviour, method and boundaries.
- A personality profile — ten traits on a 0–100 scale, rendered into the prompt at request time.
- A curriculum level — the reading age and vocabulary the persona should target.
- A model configuration — provider, model, temperature and how much history to resend.
The reason to bundle them is consistency. A "friendly maths tutor" prompt written fresh each session drifts. The same prompt, with the same traits and the same temperature, behaves the same way on Tuesday as it did on Monday.
Traits are not decoration
The personality block is rendered into the system prompt as explicit instructions —
Patience: very high (95/100) — rather than left implicit. Models follow named,
quantified instructions considerably more reliably than they infer tone from adjectives.
