Struct Instructions 

pub struct Instructions {
    pub system_prompt: String,
    pub response_schema: Option<Value>,
    pub examples: Vec<(String, String)>,
    pub metadata: Value,
}

Static persona + response contract for a cognition backend.

Fields

system_prompt: String

System prompt. Sent verbatim as the system message.

response_schema: Option<Value>

Optional JSON schema the backend must conform to. Backends that support structured outputs should enforce this; others may use it as a hint in the system prompt.

examples: Vec<(String, String)>

Few-shot examples. Each entry is (user_message, assistant_reply). Empty for zero-shot prompting.

metadata: Value

Free-form metadata (model name, temperature hint, persona tag). Backends decide which keys, if any, to honour.
