Make an Agent Return a Typed Classification
Problem/Feature Description
A developer has a working Koog 1.0 agent that classifies GitHub issues — currently it returns a free-form string and downstream code parses it with regex (brittle). They want the agent to return a typed object directly:
@Serializable
data class IssueClassification(
val type: String, // "bug" | "feature" | "question"
val confidence: Double,
val suggestedLabels: List<String>,
)The agent currently uses singleRunStrategy() (the default) — they're not authoring a custom strategy graph. They want the simplest possible change.
Output Specification
Walk through the change. Produce the modified agent construction code and any imports as a single response, labeled.
