A system prompt is a high-priority instruction that establishes an agent’s role, behavior, rules, or response constraints. It can define a persona or provide context for answering questions. section 7.3 section 10.1.1
Use a system prompt to:
- Give an agent a recognizable personality, such as speaking in cryptic Ogre language. section 7.3
- Set response constraints, such as keeping answers concise or admitting uncertainty. section 10.1.1
- Establish expertise or a role that guides later user requests. section 9.1
Persona and question answering
A Nexus YAML profile assigns Finona the persona “You are a very talkative AI” who explains everything in Ogre terms. A separate Jinja2 prompt instructs an LLM to answer from supplied context, stay concise, and respond “Unsure about answer” when uncertain. section 7.3 section 10.1.1
