🐛 Bug Description

It seems that the descriptions of the apply_manifest and create_resource in python/src/kagent/tools/k8s/_kubectl.py unintentionally mislead the agent:

• apply_manifest description: "Create a resource in Kubernetes. Must be a local file." Based on the implementation, it looks like the file doesn't need to be local. In my tests this consistently confused the agent when asked to apply a resource.

• create_resource description: "Apply a YAML resource file to the Kubernetes cluster." This seems to have a similar issue as apply_manifest

Changing these to "Apply a YAML resource to the Kubernetes cluster." and "Create a resource in Kubernetes." greatly improved the model's ability to use tools in my tests.

Please let me know if I am missing something.

🔄 Steps To Reproduce

1. Create an agent using qwen3:30b-a3b through ollama with the ApplyManifest and/or CreateResource k8s tools.
2. Ask the agent "show me an example of a nginx pod"
3. Then ask "apply the nginx pod to my local kubernetes cluster"

🤔 Expected Behavior

The agent calls either the create_manifest or the ApplyManifest or CreateResource tools with the manifest provided earlier as argument.

📱 Actual Behavior

The agent calls the ApplyManifest or CreateResource tools using a non existent 'nginx-pod.yaml' string as the argument, possibly being misled by the tool's description.
