+# gevals-kubernetes-extension
+
+A [gevals](https://github.com/genmcp/gevals) extension that provides Kubernetes resource operations for task setup, verification, and cleanup.
+
+This extension enables declarative Kubernetes interactions within gevals tasks. It also provides verification-specific operations that don't belong in MCP server tools but are essential for evaluating them. For example, waiting for a pod to reach a specific condition isn't useful as an MCP tool, but is exactly what you need to verify that an MCP server correctly modified a pod.
+
+## Operations
+
+| Operation | Description |
+|-----------|-------------|
+| `kubernetes.create` | Create a Kubernetes resource |
+| `kubernetes.delete` | Delete a Kubernetes resource |
+| `kubernetes.wait` | Wait for a condition on a resource (e.g., `Ready`, `Available`) |
+
+## Configuration
+
+Add the extension to your `eval.yaml`:
+
+```yaml
+kind: Eval
+metadata:
+  name: "kubernetes-basic-operations"
+config:
+  agent:
+    type: "file"
+    path: agent.yaml
+  mcpConfigFile: mcp-config.yaml
+  extensions:
+    kubernetes:
+      package: https://github.com/genmcp/gevals-kubernetes-extension@v0.0.1
+      config:
+        kubeconfig: ~/.kube/config  # optional, defaults to ~/.kube/config
+  taskSets:
+    - glob: tasks/*/*.yaml
+```
+
+## Task Usage
+
+Declare the extension requirement and use operations in `setup`, `verify`, and `cleanup` phases:
+
+```yaml
+kind: Task
+apiVersion: gevals/v1alpha2
+metadata:
+  name: "create-nginx-pod"
+  difficulty: easy
+spec:
+  requires:
+    - extension: kubernetes
+
+  setup:
+    - kubernetes.delete:
+        apiVersion: v1
+        kind: Namespace
+        metadata:
+          name: test-namespace
+        ignoreNotFound: true
+    - kubernetes.create:
+        apiVersion: v1
+        kind: Namespace
+        metadata:
+          name: test-namespace
+
+  verify:
+    - kubernetes.wait:
+        apiVersion: v1
+        kind: Pod
+        metadata:
+          name: web-server
+          namespace: test-namespace
+        condition: Ready
+        timeout: 120s
+
+  cleanup:
+    - kubernetes.delete:
+        apiVersion: v1
+        kind: Namespace
+        metadata:
+          name: test-namespace
+        ignoreNotFound: true
+
+  prompt:
+    inline: Create an nginx pod named web-server in the test-namespace namespace
+```
+
+## Operation Reference
+
+### kubernetes.create
+
+Creates a Kubernetes resource using standard manifest fields.
+
+```yaml
+- kubernetes.create:
+    apiVersion: v1
+    kind: Pod
+    metadata:
+      name: my-pod
+      namespace: default
+    spec:
+      containers:
+        - name: nginx
+          image: nginx:latest
+```
+
+### kubernetes.delete
+
+Deletes a Kubernetes resource. Use `ignoreNotFound: true` to skip errors when the resource doesn't exist.
+
+```yaml
+- kubernetes.delete:
+    apiVersion: v1
+    kind: Namespace
+    metadata:
+      name: my-namespace
+    ignoreNotFound: true
+```
+
+### kubernetes.wait
+
+Waits for a condition on a resource. Supports configurable timeout and expected status.
+
+```yaml
+- kubernetes.wait:
+    apiVersion: apps/v1
+    kind: Deployment
+    metadata:
+      name: my-deployment
+      namespace: default
+    condition: Available
+    status: "True"    # optional, defaults to "True"
+    timeout: 5m       # optional, defaults to 60s
+```
