# Cobalt Core Domain skill for the [cobaltcore-dev](https://github.com/cobaltcore-dev) project family — SAP Converged Cloud infrastructure components for KVM hypervisor management, metrics collection, and compute-node tooling. ## Reference Loading Table | Signal | Reference | Size | |--------|-----------|------| | kvm-exporter, metrics, prometheus, libvirt, hypervisor, collector, scrape, steal time, NUMA, cgroups, cloud hypervisor | `references/kvm-exporter.md` | ~800 lines | | goroutine, concurrency, semaphore, TryLock, sync.Map, race condition, socket exhaustion, scrape overlap, ClearScrapeCache | `references/concurrency-patterns.md` | ~200 lines | | test, mock, moq, unit test, E2E, Kind cluster, race detector, interface_mock_gen, test-metrics.sh | `references/testing-patterns.md` | ~200 lines | **Loading rule.** Read the references whose signals match the task before responding. --- ## Phase 1: IDENTIFY Determine which cobaltcore component the user is asking about. | Component | Repository | Reference | |-----------|-----------|-----------| | KVM Exporter | `cobaltcore-dev/kvm-exporter` | `references/kvm-exporter.md` | If the component is not listed, tell the user no reference exists yet and offer to analyze the repo. **Gate**: Component identified. Reference loaded. Proceed to Phase 2. --- ## Phase 2: RESPOND Use loaded reference knowledge to answer the user's question. The references contain: - Architecture and data flow diagrams - Complete metric catalogs w...
