A community-pool bot should look up tonight's lap-lane hours from a small internal function when a swimmer asks when the lanes open. How should the orchestrator handle that?
Select an answer to reveal the explanation.
Short Explanation
When a swimmer asks when the lanes open, the orchestrator picks the hours function, runs it, and continues the chain with the real time. That is light tool use, not an agent OS, a winter-pretraining guess, a volunteer text, or an overnight retrain.
Full Explanation
Light tool use is an orchestrator decision: select a small function, run it in the app, and continue the chain with the result so the model can answer with a real time. That is not an agent operating system and not a reason to retrain. Ignoring the function, or pasting hours by hand, leaves the model guessing from stale pretraining.
