Method Summarize

pkg/runtime/runtime.go:1829–1831

Summarize generates a summary for the session based on the conversation history. The additionalPrompt parameter allows users to provide additional instructions for the summarization (e.g., "focus on code changes" or "include action items"). Summarize is the public entry point used by user-driven /c

(ctx context.Context, sess *session.Session, additionalPrompt string, events EventSink)

// Internal callers (proactive threshold, overflow recovery) use
// [LocalRuntime.compactWithReason] directly to forward a more specific reason.
func (r *LocalRuntime) Summarize(ctx context.Context, sess *session.Session, additionalPrompt string, events EventSink) {
	r.compactWithReason(ctx, sess, additionalPrompt, compactionReasonManual, events)
}

// compactWithReason runs a session compaction with the supplied reason and
// emits a TokenUsageEvent so the UI immediately reflects the new context
