Tools (8)
diagnoseWalk the tree from a resource, rank blocking resources (deepest first) with full messages + recent events. **Start here** when you know the resource.
Parameters not published.
get_resourceOne resource, pruned to conditions, recent events, and spec — plus `paused` and, while terminating, `deletionTimestamp` + `finalizers`.
Parameters not published.
get_resource_treeThe composition tree as a flat, parent-indexed node list with per-node Ready/Synced/Healthy state. Native Kubernetes resources composed by a v2 XR report `Unknown` — they never carry those conditions, and are never named as diagnose suspects.
Parameters not published.
list_configurationsConfiguration packages, same shape — the trail when Compositions/XRDs an XR needs are missing.
Parameters not published.
list_contextsAvailable kubeconfig contexts.
Parameters not published.
list_functionsComposition Function packages, same shape — a crashlooping function pod is invisible from the XR. Needs Crossplane >= 1.14 (`v1beta1` Functions on 1.14–1.16 resolve too); older clusters get an explanatory note, not an unexplained empty list.
Parameters not published.
list_providersEvery Provider package with installed/healthy state; failing ones add full condition messages, events (e.g. the `UnpackPackage` registry error), per-revision health, and upgrade-skew notes. **Escalate here** when a managed resource's error is cryptic.
Parameters not published.
list_unhealthyTriage the whole cluster: list composite resources (XRs) and claims that are not Ready/Synced — tiny rows ready to feed straight into `diagnose`. A resource being deleted is returned even when its conditions still say Ready (a dead reconciler freezes them) and is counted under `terminating`. **Start here** when you don't yet know *what* is broken.
Parameters not published.
