+  shortDescription: AI-powered Kubernetes assistant
+  description: |
+    This plugin provides a natural language interface to carry out kubernetes
+    related tasks. The plugin can plan and execute multiple steps given a high
+    level description of a task.
+    It's important to note that this plugin does not replace kubectl. Instead,
+    it makes kubectl accessible to non-kubernetes users and makes kubectl users
+    more productive because now they don't have to remember all the syntax and
+    commands to perform common tasks.
+  caveats: |
+    This plugin uses AI models (LLM) to plan and execute tasks. It supports
+    multiple LLM providers such as Gemini, Azure-OpenAI, Ollama, llamacpp.
+    You can get the API key for the default provider (Gemini) from
+    https://aistudio.google.com/app/apikey.
