Method compactionContextLimit

pkg/runtime/session_compaction.go:173–189

compactionContextLimit returns the context-window limit of the model that generates the summary: the dedicated compaction model when one is configured, otherwise the agent's own model. Returns 0 when it can't be resolved. Failure is non-fatal: a before_compaction hook may supply its own summary and

(ctx context.Context, a *agent.Agent)

// pass the cloned summary-call provider so its provider_opts (which
// match the underlying model) are considered.
func (r *LocalRuntime) compactionContextLimit(ctx context.Context, a *agent.Agent) int64 {
	if a == nil {
		return 0
	}
	model := a.CompactionModel()
	if model == nil {
		model = a.Model(ctx)
	}
	if model == nil {
		return 0
	}
	summaryModel := provider.CloneWithOptions(ctx, model,
		options.WithStructuredOutput(nil),
		options.WithMaxTokens(compactor.MaxSummaryTokens),
	)
	return r.resolveContextLimit(ctx, summaryModel, summaryModel.ID())
}

// effectiveContextLimit returns the context budget the running session
// operates within: the primary model's window, capped by the dedicated
