Design an agent that investigates support tickets automatically

Design an AI agent that picks up incoming support or on-call tickets and investigates them before a human does: it reads the ticket, gathers evidence from logs, dashboards, code and past incidents, and writes up a likely cause and next steps.

Discuss the tools the agent can call and their permissions, how it plans and when it stops, how results are handed to people, how you measure whether its investigations are right and useful, and how it fails safely.
