Enterprise SRE Autonomous Diagnostic & Tool-Calling Traces (Community Preview)
Overview
Autonomous infrastructure agents routinely fail in production when models hallucinate CLI arguments, generate invalid diagnostic syntax, or jump to speculative remediations without observing system feedback.
This repository hosts the Community Preview (250 verified traces) of an end-to-end site reliability engineering (SRE) fine-tuning corpus covering Kubernetes, Kafka, Redis Sentinel, PostgreSQL, Istio/Envoy, Linux Kernel, and AWS IAM. Each trace pairs real-world alert telemetry with step-by-step diagnostic reasoning, structured tool invocation, synthetic environment output, and verified infrastructure remediation.
