umodel-query

Read from a UModel object-graph semantic layer with the umctl CLI (MCP alternative noted). Three kinds of read: (1) entities & relationships / topology (.entity, .topo) and (2) the model itself (.umodel, and .entity_set methods) return real rows; (3) metrics & logs (get_metrics / get_logs) return an executable *plan* — PromQL / Elasticsearch DSL with the entity id pre-substituted — that you run against the backend. Against a PaaS endpoint the same calls return data rows instead of a plan. Use to query or read UModel entities, relations, topology, or model metadata; to read a service's metrics or logs; to look up services and dependencies; or to discover what objects, datasets, and methods exist. For root-cause analysis on top of these reads, see the umodel-rca skill.
