Method executeAfterCompactionHooks

pkg/runtime/hooks.go:522–540

executeAfterCompactionHooks fires after a successful compaction has applied a summary to the session. Purely observational — the result is discarded. The Input carries the *pre-compaction* token counts (what was summarized), not the new ones, so handlers can naturally express "compacted from X to Y

(
	ctx context.Context,
	sess *session.Session,
	a *agent.Agent,
	reason string,
	contextLimit int64,
	preInputTokens, preOutputTokens int64,
	summary string,
	events EventSink,
)

// "compacted from X to Y". The post-compaction counts are reflected
// in the next [NewTokenUsageEvent] the runtime emits.
func (r *LocalRuntime) executeAfterCompactionHooks(
	ctx context.Context,
	sess *session.Session,
	a *agent.Agent,
	reason string,
	contextLimit int64,
	preInputTokens, preOutputTokens int64,
	summary string,
	events EventSink,
) {
	r.dispatchHook(ctx, a, hooks.EventAfterCompaction, &hooks.Input{
		SessionID:        sess.ID,

// executeUserPromptSubmitHooks fires user_prompt_submit once per user
