Role + objective
State who the model is and what success looks like before the task.
When to use
Almost every non-trivial prompt.
How to apply
Open with a concrete role and a measurable objective; keep them separate from constraints.
Glossary
- role
- Who the model should act as (expertise, stance, audience) before it starts the task.
- objective
- What success looks like in measurable terms — the outcome, not the vibe.
- constraints
- Hard boundaries kept separate from the role/objective so rules don’t blur into goals.
