Start with the job, not the model
A useful business agent begins with a specific responsibility: guide a visitor toward the right service, help staff retrieve approved knowledge, qualify a request, or prepare a handoff. We define the user, the information source, the acceptable answer, the moment a person must take over, and the evidence that the interaction was useful before selecting a model or interface.
Separate conversation from authority
Answering a question and changing an external system are different risk levels. Crelyvo keeps guidance, recommendations, data access, and external actions separate. Any future action—sending a message, creating a booking, modifying a record, or triggering a workflow—requires scoped credentials, server-side validation, auditability, explicit limits, and a recovery path.
Evaluate the uncomfortable cases
A polished happy path is not enough. Evaluation covers ambiguity, missing knowledge, prompt injection, oversized input, unavailable providers, rate limits, prohibited claims, privacy boundaries, and requests outside the approved role. The result is a narrower agent that communicates uncertainty clearly and hands control to a person instead of pretending to complete work.
