Start by splitting agent questions into three lanes.
The simplest usable system is not a bigger approval inbox. It is a lane model: immediate escalations, same-day batches, and policy-learning repeats.
Batching works only when urgency has a separate path.
If every question waits for the daily review, the agent may miss account risk, sensitive replies, or time-bound decisions. If every question interrupts immediately, the agent becomes another noisy app.

Immediate lane
Security, money, account access, public commitment, sensitive contact, or near-deadline action.
Daily batch
Non-urgent decisions that benefit from human judgment but do not need real-time attention.
Policy lane
Repeated questions that should become rules, not permanent review items.
