RouteZero — Autonomous Incident Routing

RouteZero is a four-agent autonomous incident routing system built for engineering teams drowning in manual triage. When a production incident occurs, engineers paste a stack trace and RouteZero handles the rest. Agent 1 (Classifier) uses zero LLM calls — pure deterministic regex and keyword scoring — to classify the failure type, detect the affected service, and assess blast radius. Every decision is fully auditable. Agent 2 (Router) applies rules-first priority logic: critical path plus production automatically escalates to P1, SLA breaches under 60 minutes trigger P1, and deployment timing enables probable cause detection. LLM is only consulted when confidence falls below 65%. Agent 3 (Ticket Writer) uses Fireworks AI with Gemma to assemble role-appropriate content for three stakeholders simultaneously — a full technical ticket for the engineer, a leadership-framed summary for the team lead, and a five-sentence plain English digest for the manager. A hallucination validator rejects any number or filename in AI output not present in the verified input facts. Agent 4 (Architectural Auditor) mines incident history for recurring patterns — same file and line number across multiple incidents, service stress signatures, and cascading failures — then files proactive PLM tickets before the next incident happens. A human approval gate sits between routing and action. Nothing is created or sent until the engineer clicks approve. Built on FastAPI, Streamlit, DuckDB, and Fireworks AI.
