Struct GoalEvaluator 

pub struct GoalEvaluator { /* private fields */ }

Calls the LLM provider to decide whether a goal condition is met.

Implementations

impl GoalEvaluator

pub fn new(provider: Arc<dyn ChatProvider>) -> Self

Create an evaluator backed by provider.

pub async fn evaluate( &self, condition: &str, transcript: &[Message], ) -> Result<GoalVerdict>

Evaluate condition against the given transcript.

Callers are responsible for pre-slicing transcript to the desired number of recent messages (e.g. via [AgentRuntime::transcript_tail]). This method uses the full slice as-is — it does NOT perform any further truncation.

Calls the provider with a minimal YES/NO prompt (max_tokens ≈ 256 via a short system instruction). The first word of the response determines the verdict; any remaining text is kept as reason.
