up dep add xpkg.upbound.io/upbound/function-claude-status-transformer:v0.0.0-20250703165412-f44b846b3a

2. Within your Composition add a pipeline step that includes the function:

apiVersion: apiextensions.crossplane.io/v1
kind: Composition
metadata:
  name: xnetworks.example.upbound.io
spec:
  compositeTypeRef:
    apiVersion: example.upbound.io/v1alpha1
    kind: XNetwork
  mode: Pipeline
  pipeline:
  ...
  - functionRef:
      name: upbound-function-claude-status-transformer
    input:
      apiVersion: function-claude-status-transformer.fn.crossplane.io/v1beta1
      kind: StatusTransformation
      additionalContext: ""
    step: upbound-function-claude-status-transformer
    credentials:
